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 the assembly, 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 an actuator housing. The contacts are normally open or normally closed depending on the switch construction. Movement of the cover forces the actuator to cause a torsion spring switch piece to bridge a gap between the contacts in a normally open switch and moves the switch piece from between the contacts in a normally closed switch.
