Is there a thing-a-ma-bob to force two normal 120V toggle switches to be switched together? In other words, I want to place two toggle switches (normal style, not Decora obviously) in a single box and wire them each separately. But I want to force the switches to be moved together -- either both are ON or both are OFF, but never one ON/one OFF.
I'm thinking of something like the bracket you see on multi-pole breakers, but for normal toggle switches instead (see circled item in image). Does anything like this exist?
