abstract. abstract. Safety Moment. DEAD MAN’S SWITCH.

A DEAD MAN’S SWITCH is the switch that is designed to be activated automatically if the human operator becomes incapacitated, such as through death, loss of consciousness, or being bodily removed from control. Originally applied on power tools machinery..

These switched are usually used as a form of fail-safe where they stop the machine with no operator from potentially dangerous action or incapacitate a device as a result of accident, malfunction, or misuse. They are common in such applications in power tools, rotating equipment, moving equipment, freight elevators, outboard motors, chainsaws. On some machines, these switches merely bring the machines back to a safe state, such as reducing the throttle to idle or applying brakes while leaving the machines still running and ready to resume normal operation once control is re-established..
