9Sometimes they're used for {{Block Puzzle}}s. Sometimes they're to make sure you need two people to get through an area. Sometimes they just mean you don't have to press the use button. And sometimes they're just barely discernible and you [[BoobyTrap really don't want to step on them]]. Whatever the case, a surprising number of mechanical doors are hooked up to pressure plates. Common in puzzle platformers. Often, there are two distinct types: one that stays pressed and active when you step off, and one that doesn't and needs to be held down by a box or something else.

15[[folder:Live-Action Film]]
16* In ''Film/DrWhoAndTheDaleks'', entry to the Dalek citadel required pressing down a raised platform position ten meters or so away. It must stay down for the doors to remain open, and it takes them a minute to realize that one of the party needs to apply weight to the mechanism while someone else holds the door open long enough for that person to sprint through. (Needless to say, the Podcast/RiffTrax version makes fun of both the existence of the mechanism and of Who and company being briefly detained by it.)
17* The Masked Gang's secret lair entrance in ''Film/MaskedAvengers''. It's a DilatingDoor triggered by a switch that needs to be held down, else it closes on its own mere seconds later. The gang's minions are well aware of this trap, but when the heroes tries infiltrating the place in the end the first {{redshirt}} who stepped over gets his midsection crushed by the closing door.

21* ''TabletopGame/DungeonsAndDragons'' players ''dread'' the activation of a pressure plate, because nine times out of ten, it will set off a nasty trap that will ruin your whole day.
22* Subverted in one of the ''TabletopGame/GrimtoothsTraps'' books for d20 systems, which features the "Click Plate", a pressure plate that gives an ominous click when you step on it... [[MindScrew And does nothing else]]. No problem... unless you intersperse them in a trapped dungeon with other plates that go click just before the trap goes off...

25[[folder:Video Games]]
26* The Wii version of ''VideoGame/ABoyAndHisBlob'' has them all over the place. These makes some of the platforms and doors move.
27* On your way to the Red Queen's domain in ''VideoGame/AmericanMcGeesAlice'', you need to retrieve an insane child (who ran off the pressure plate) back to stand on it to open the gate to the portal.
28* ''VideoGame/AliceMadnessReturns'' has a number of these, although the first couple are of the variety that seem to give you as much time ''after'' the plate is pressed as you remained on the plate. After you get the Clockwork Bomb, most take the form of "Drop a Clockwork Bomb on the plate, then hurry-up-and-do-the-thing-that-that-enables-before-the-bomb-detonates". When they raise switches that you have to platform over to a good spot to then aim for and shoot until they turn green, they can be the most frustrating non-combat parts of the game.
29* ''Bloodwych'', which includes puzzles where you have to either leave a party member behind on a pressure plate, or (if playing multiplayer) have the other player's party stand on the pressure plate.
30* ''VideoGame/ChipsChallenge'': The brown-colored buttons have to be kept pressed, whether by Chip or a block, so the traps connected to them remain disabled.
31* ''VideoGame/TheCrownOfWu'' contains a few pressure plate-activated exits, which can be triggered by dragging Chinese stone lion statues around and placing them upon the plates.
32* ''VideoGame/DeadlyRoomsOfDeath'' has three varieties of pressure plates. One kind activates objects exactly once, another activates objects every time it gets stepped on, and the final kind activates and deactivates things when it gets stepped on and off. Puzzles can use them in all sorts of ways. The player can activate them directly, or can guide monsters onto them at convenient times. All sorts of objects can hold them down as well.
33* ''VideoGame/DevilMayCry'':
34** In ''VideoGame/DevilMayCry4'' and ''VideoGame/DevilMayCry5'', standing on certain special platforms (called Continuum Pads in ''4'') reveal or activate a nearby Grim Grip that you can grapple on.
35** Mission 11 of ''Devil May Cry 4'' also has two stone pressure plates that must be [[TwoKeyedLock pushed at the same time]] to open a gate.
36* ''VideoGame/DragonAgeOrigins'' has them as trap triggers.
37* ''VideoGame/DwarfFortress'' has plates with triggering conditions adjustable at the construction time and whether your own citizen and pets must avoid it.
38** Usually instead of pressing them yourself to do things, you get others to press them. One example is a pair of pressure plates [[TacticalDoorUse that open and close doors or bridges]], then chain up an animal on either end, load it with automated traps, and get goblins to run down it. When they hit a plate, it closes the bridge they're running towards, preventing them from pathing to the cat chained on that end, so they reverse direction and head the other way. Over the traps. ArtificialStupidity can be fun as well as !!FUN!!.
39** Pressure plates also react on the weight of water (or even magma, if made of materials ''that'' heat-resistant) or more recently added minecarts, and currently are the only sensor other than levers that can control mechanisms. Thus these are included in all automation assemblies, whether running functions useful in the game (flood safeguards, defenses, drowning-safe timed flush swimming rooms, weight-sensitive automated cattle butchery, etc) or assembled in "dwarfputers" as a SelfImposedChallenge. Plates can control floodgates, hatches and bridges used as valves, which [[http://dwarffortresswiki.org/index.php/Fluid_logic opens great possibilities]] for hydraulic automata and other contraptions -- whether [[http://dwarffortresswiki.org/index.php/Computing#Creature_logic creature logic]] elements using [[TheAllSeeingAI pathfinding routines]] or mechanic elements activating water pumps or [[http://dwarffortresswiki.org/index.php/Minecart_logic minecart-controlling]] components.
40* ''Franchise/TheElderScrolls'':
41** ''VideoGame/TheElderScrollsIVOblivion'' and ''[[VideoGame/TheElderScrollsVSkyrim Skyrim]]'' use them as trap triggers. Like ''VideoGame/{{Fallout 3}}'', ''Skyrim'' has a perk which prevents the PlayerCharacter from setting off pressure plate traps, but said perk doesn't apply to your ''followers'', meaning that, if you're not careful, you can still die a horrible, spiky death as a result of your follower haplessly stepping on the trap trigger you presumably deftly avoided.
42** A cave-dungeon in the fifth game's ''Dawnguard'' DLC introduces a variant: several pressure plates must be triggered together to open a particular gate, while a bridge and a couple of other gates must be triggered by somehow setting off pressure plates mounted vertically on targets some distance away.
43* ''VideoGame/EtrianOdysseyNexus'': One of the gimmicks introduced in the final standard stratum is the presence of platforms that, upon being stepped on and then walked away from, either lower into the ground's level or rise to the level of the middle walls' paths, depending on their previous state. These act effectively as columns whose motion is operated by the weight of the party characters, and working with them is necessary to make way through the first and fifth floors.
44%%* ''VideoGame/EvilGenius'' has them too.
45* The old ''VideoGame/EyeOfTheBeholder'' games have doors (and various other mechanisms) triggered by pressure plates in the floor. Though they're not that hard to notice, they're generally on paths that the party cannot avoid. Or next to a combat encounter, meaning that if you use your mobility in a fight you're very likely to step on it accidentally. Also, monsters can press them too — sometimes, the trap is triggered by the release of a pressure plate where a monster is standing until the party kills it.
46* ''VideoGame/{{Fallout}}''
47** ''VideoGame/Fallout3'' has traps that can be set off by a pressure plate. With a high enough Repair skill, you can disarm the plate before stepping on it- if you notice it. There's also a perk called Light Step which means that your character can ''jump up and down on the plate'' and still never set it off.
48** Earlier ''Fallout'' titles used pressure plates for a variety of traps ranging from the classic spear-thrower to explosive mines. Players could use the Trap skill to detect and defuse traps for a small amount of XP. A CriticalFailure when attempting to defuse a trap usually set it off.
49* In ''[[VideoGame/GanbareGoemon The Legend of the Mystical Ninja]]'', one hallway in Zone IV includes hidden pressure plates that activate slot machine-like spinners. The result determines what falls from the ceiling: prizes or enemies or bombs.
50* ''VideoGame/TheGirlAndTheRobot'': There are a [=LOT=] of puzzles in this game that revolve around having either the girl or the robot stand on a pressure pad.
51* A few puzzles in ''VideoGame/{{Gish}}'' feature this.
52* ''VideoGame/{{GoldenEye}}'' uses a puzzle like this in the Aztec level, [[GuideDangIt based on]] ''Film/TheManWithTheGoldenGun''.
53* ''VideoGame/{{Jumper}}'' and ''Jumper Two'' feature several such puzzles.
54* ''VideoGame/KingsQuestMaskOfEternity'' had these. You're meant to hold them down with rocks, but you can avoid this if you manage to kill a monster so that it falls on the plate.
55* ''VideoGame/KittyMayCry'' have several closed doors that can only be opened by stepping on pedals, where your feline protagonist can activate them by carrying wooden blocks and placing them on the switch. Sometimes you'll need to lug a block around, in areas containing ''two'' doors and only one block.
56* ''VideoGame/LaMulana'' features placing bags of sand on pressure plate pedestals as a primary game mechanic. There are also the tiles which you have to [[BlockPuzzle push blocks]] onto, several of which cause other blocks to appear out of thin air. There are also the old standby "step on it and something happens" type, although they're relatively rare.
57* Pressure plates are found throughout ''VideoGame/LegendOfGrimrock'', used to raise/lower gates and activate {{trap door}}s.
58* ''Franchise/TheLegendOfZelda'':
59** The majority of games use pressure plates as switches to open doors. Depending on the case, these switches are likely to show a different color to indicate that they won't stay pressed if Link steps onto them (for example, in ''Ocarina of Time'', they are colored gray, while the regular switches are colored ocher).
60** Some games take this trope further by including some floor switches that cannot be tripped with Link's weight alone. For example, a couple of floor switches in the "Inside Jabu-Jabu" dungeon in ''[[VideoGame/TheLegendOfZeldaOcarinaOfTime Ocarina of Time]]'' require Link to be carrying Princess Ruto while stepping on the switch. In ''[[VideoGame/TheLegendOfZeldaMajorasMask Majora's Mask]]'', some switches can only be tripped by the heavy Goron Link.
61** ''VideoGame/TheLegendOfZeldaBreathOfTheWild'' has some switches that requires an object to hold it down and larger switches needs heavier and larger objects to stay active.
62* Core part of the puzzle system in ''VideoGame/LifeGoesOn'' is finding a way to get something to weigh down a pressure plate to proceed to the level goal. Said something is normally [[BlackComedy a corpse]].
63* ''{{Videogame/Mari0}}'', being a crossover with ''{{Videogame/Portal}}'', naturally has these.
64* These show up in the EdutainmentGame ''Math Blaster 2: Secret of the Lost City''.
65* ''{{VideoGame/Minecraft}}'' allows the player to craft four kinds of them: stone plates, which can only be triggered by the player or mobs, wooden ones, which can also be triggered by dropped items, and two kinds of metal ones, which are ''only'' triggered by dropping items on them. Gold pressure plates output a signal strength of 1 per item, and iron ones output a signal strength of 1 per 10 items, rounded up.
66* ''VideoGame/{{Patapon}} 3'' has pressure plates in some of the dungeon levels to open gates and stuff.
67* There is a simple BlockPuzzle in the last level of ''VideoGame/PerfectDark'' which is needed to reach the final boss.
68* ''Franchise/{{Pokemon}}'':
69** [[VideoGame/PokemonRedAndBlue First-generation]] ''Pokémon'' games and their remakes featured these in Victory Road, in the form of a BlockPuzzle.
70** ''VideoGame/PokemonXD'' has pressure plates that you keep activated by pushing boxes of Poke Food onto them. Now if some of them didn't reset every time you left the room....
71* ''{{VideoGame/Portal}}'''s many, ''many'' Super Buttons. They usually require you to put a Weighted Storage Cube on them.
72* The 2-D ''Franchise/PrinceOfPersia'' games made extensive use of pressure plates to open or close distant doors; they could be held down permanently by killing a {{Mook}} over them or dropping a TemporaryPlatform on them. The ''Sands of Time'' saga has more variations of them; some are placed on walls and must be activated by wall-running, while some require a heavy object to keep them down.
73* In ''VideoGame/ResidentEvil5'', the Ndipaya tribe are apparently very fond of these as even their heavily-guarded ancient ruins feature these.
74* ''VideoGame/RiseOfTheTriad'' uses "touchplates" a lot; on the easy difficulty, the game tells you when you have triggered them and what they just did.
75* In ''VideoGame/RiskOfRain2'', a puzzle in the Abandoned Aqueduct requires holding down two pressure plates to unlock a sealed chamber. This task is complicated by the fact that, in single player, only a few characters and items have the means to independently trigger both plates (Engineer is the most convenient option, since he can place turrets on the plates). Inside the chamber are a pair of late-game enemies that unlock special items when killed.
76* ''VideoGame/TheSimpsonsGame'' parodied this among many other video game tropes.
77* ''VideoGame/TheSims3: World Adventures'': There are two types of these in the tombs you traverse on your adventures: the kind you just need to step on once to (unlock a door/disable a trap), and the kind that requires constant weight (like say, from a moveable statue in the room).
78* ''[[VideoGame/LegacyOfKain Soul Reaver]]'' beat the Christ out of this trope as part of its beating-the-Christ-out-of the Block Puzzle.
79* ''Videogame/StealthBastard'' has pressure plates as common puzzle elements which can be pushed down by platforms, player, blocks and robots.
80* ''VideoGame/SuperMarioParty'': The minigame FetchQuest (yes, it's called like that) requires all four players to team up and carry all nine diamonds placed in their underground area into the pedestals placed at the center. The problem is that some of the diamonds are locked behind barriers that can only be opened as long as their associated switches are held pressed. Thus, one player has to stand on a switch to keep it pressed so another player can get the diamonds placed beyond the now-open barrier.
81* In one of ''VideoGame/TalesOfSymphonia'''s many BlockPuzzle areas, one of them (in an AbsurdlySpaciousSewer) had a PressurePlate you had to slide a block onto. There were other instances similar to this, but only the sewer one was a blatant PressurePlate.
82* ''VideoGame/{{Terraria}}'' also has these, either purchased from the mechanic for 20 silver a pop or found naturally in caves hooked up to a BoobyTrap. The trigger conditions also vary depending on the color: Green and Red will trigger when anything steps on it, Gray, Brown, Blue and Lihzahrd will only trigger for players and Yellow will trigger for anything ''but'' the player stepping on it. Teal Pressure Pads are unique in that they only trigger when a pet or projectile touches it. Weighted Pressure Plates send a signal when stepping onto it and again when stepping off.
83* ''[[{{VideoGame/Thief}} Thief: The Dark Project]]'' has pressure plates, used both for triggering traps and activating mechanisms such as doors. Weighting them down with junk can be useful for both kinds.
84* Pressure plates are featured in the first two games of ''VideoGame/ThisIsTheOnlyLevel'', which is pressed to unlock the gate to the next stage [[spoiler:(sometimes)]].
85* A staple of ''Franchise/TombRaider'' games. Many of them require a block to keep the plate pressed down so a door or other mechanism stays active.
86* The map [=WAR-TankCrossing=] in ''VideoGame/UnrealTournamentIII'' has pressure plates for tanks. They are necessary to take down the Cores.
87* ''VideoGame/VampireTheMasqueradeBloodlines'' features these as trap buttons to ensnare the unwary during the endgame.
88* ''VideoGame/WarcraftIII'' often features these in dungeons as door openers or elevator buttons. In the expansion's undead campaign, there's a puzzle where an elevator needs a plate activated to work, but there's only room for one unit. The solution is to leave an item on the switch.

91[[folder:Webcomics]]
92* ''Webcomic/DungeonsAndDoodlesTalesFromTheTables'': Episode 10 has a room full of pressure plates, thankfully previously marked by scholars. Unfortunately, Redwen tries checking the room by darkvision alone before going through, missing all the red markings (since darkvision doesn't show colors). BOOM!
93[[/folder]]

95[[folder:Web Videos]]
96* Pressure plates are frequently used by ''WebVideo/SMPLive'' players within traps, especially in Cooper's many pitfall traps scattered across the map.
