Big Electric Switch
When you want to activate a Weapon of Mass Destruction, a Mad Scientist's invention, an electricity-based method of execution (especially an electric chair), or other badass electric device to be suitably dramatic, you have two options. One of them is the Big Red Button, and the other is the old-fashioned electric switch with a huge handle, which sends sparks flying when activated. Called a "knife switch" in supply catalogs and that other wiki. While the Big Electric Switch is obviously common in Steam Punk and period pieces (including neo-retro Film Noir pastiches like Sin City), it can make surprising appearances even in technologically advanced contexts, despite the obvious anachronism.

- The infamous opening bout of the 1991 edition of WCW Halloween Havoc, an eight-man "Chamber of Horrors" match pitting the team of Sting, El Gigante, Rick Steiner, and Scott Steiner against the team of Scott The Diamond Studd (Scott Hall), Big Van Vader,Cactus Jack (Mick Foley), and Abdullah the Butcher. The match took place in a steel cage filled with weapons; the object of the match was to place a member of the opposing team in the electric chair in the center of the ring and pull the Big Electric Switch, thus "electrocuting" him (no electricity was involved, just pyrotechnics and overacting). The match can be found in three parts, but non-masochists may wish to skip to the third part. Sting's team won when Cactus Jack inadvertently threw the switch while his teammate Abdullah was in the chair, thinking that opponent Rick Steiner was seated there instead. The real winners were Oz (Kevin Nash), The One Man Gang, and Barry Windham, all of whom were scheduled to participate in the match but, for various reasons, didn't do so, and were replaced by Vader, Foley, and Abdullah. This was an early inductee into WrestleCrap.

- Many early electrical switches really did look like this. It's a simple, easy-to-build design.
- Likewise, you still see knife switches in some low-power learning kits, because you can actually see the switch working.

- When the KTLA TV station switched from analog to digital, it was done with a deliberately anachronistic Big Electric Switch.
- Though obsolete today, knife switches are still in use in older installations.
- Knife switches and other steampunkish looking large switches are very useful when it comes to really strong currents, from hundreds of amperes in starter circuits of trucks or locomotives to thousands of amperes in large industrial installations, as they're essentially a movable busbar. Modern age switches can drop it because they use relays instead, which can be operated from electronic control panels.
- Knife-shaped and water-tap-shaped switches◊ are sold to provide a very quick cut-off in emergency, directly at the battery terminal for large automotive / truck batteries. They are very simple inside (mostly a thick movable piece of copper) and they can easily withstand 1000 amps.
- Knife switches have largely fallen out of favor because they're dangerous. Note the bare pieces of metal making contact with the receivers. Considering the voltages and amperages running though a typical knife-switch-controlled circuit, it would be very easy to electrocute yourself if you accidentally brushed up against the wrong part.
- That, and if you try to open the switch while it's driving a large inductive load, you will get a plasma arc and won't be able to interrupt the circuit. That's why large switches meant to quickly cut power to motors have been replaced either by devices with integrated solid state shunts/flyback diodes and/or vacuum-sealed or noble-gas purged cells with big insulating doors to interrupt the arc, instead of being just exposed to air.
- Shore power installations for ships usually have these.
- Because of their simplicity and ability to handle massive currents, electrical utilities use what are essentially massively upscaled and remotely actuated versions of knife switches to connect and disconnect power lines. Their operation can be quite spectacular.
