Abstract
A safety switch assembly for de-activating a motor vehicle if a user is not positioned on a vehicle seat. The assembly includes a base for mounting a switch, a cover that moves in response to the presence of a vehicle operator on the seat, and an actuator that moves with the cover to open and close switch contacts inside a switch housing. The base is constructed to pass through a cutout in a vehicle seat pan and includes extensions that also pass through the cutout. The projections are inhibited from movement back through the cutout after the base is rotated from an orientation that allows the projections to be inserted through the cutout to an orientation in which the projections overlie the seat pan.
