A lockable switch mechanism for a machine guard includes a switch plunger and locking and switch mechanisms. The plunger moves, upon insertion of an actuator, between two positions to actuate the switch mechanism and is locked by the locking mechanism, which has one locking member biased against a surface of the plunger and another locking member that is displaceable between locked and released positions. The plunger has an annular shoulder that displaces the first locking member when the plunger is moved. The second locking member prevents displacement of the first locking member by the plunger to thereby prevent movement of the plunger. Thus removal of the actuator is prevented unless the second locking member has been moved to the unlocked position when the machine is in a safe condition.
