Abstract

A Hall effect safety switch assembly for de-activating a motor vehicle if a user is not positioned on a vehicle seat. The assembly includes a switch frame for mounting the assembly, a magnet and a hall effect sensor mounted to the switch frame in a spaced apart relationship, and a vane that moves in response to the presence of a vehicle operator on the seat that causes the Hall effect sensor to provide an inhibit signal that prevents an engine from running.
