Default Re: Brake..Motor kill switch.

those are called micro switches and we use them at work on level controls to STOP compressors when the liquid gets either too low or too high. they are used in all kinds of operations I've seen them on aircraft landing gears used to keep the gear from retracting when there is weight on the gear and the gear up switch is accidnetly moved to the up position just one of the many places they are used. some are normaly open and some are normaly closed.
