Exercise machine safety switch

摘要

An exercise machine has an electrical safety switch which switch includes a base with a switch actuator attached thereto. A paddle is rotatably attached to the base for movement toward and away from the actuator. The paddle has an upper element and a lower element to form a void therebetween. The lower element as an aperture through which the actuator passes when the paddle is depressed. Placement of an enabling card in the void obstructs the aperture and enables operation of the actuator between "on" and "off" positions by depression of the paddle. Removal of the enabling card prevents accidental actuation of the machine.
