Abstract
Abstract A switch for installation in an automotive vehicle, the switch preventing theft of the automobile by not allowing the engine to be started unless an exact key is used to trip a latch that holds the fuel valve in an open position, the switch including means to receive either a long key for normal use by a motorist, or a short key that can be surrendered to a parking attendant, the short key allowing the engine to be started so the vehicle can travel on what little fuel is in the carburator but which does not open the fuel valve for a continuous engine operation.
