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 Steampunk 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 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 Kevin "Oz" 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.

Real Life

 * 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.
 * Every "switch" flipped to light a community Christmas tree appears to be one of these. In truth, the tree lighting is controlled not by a huge switch, but an offscreen/offstage electrical crew.
 * 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. Modern age switches can drop it because they use relays instead, which can be operated from electronic control panels.
