Abstract

A rotary electric switch, for example an automotive igni­ tion switch, has a rotor, a case holding the fixed contacts and an interlock mechanism. The interlock mechanism comprises a plunger and an interlock member carried by the rotor and a cam­ form on the case which cooperates with the plunger to limit movement of the rotor relative to the case. The interlock mem­ ber and plunger coact to normally retain the plunger out of con­ tact with the camform. At a given position of the rotor the plunger is released, whereby subsequent movement of the ro­ tor again to the given position is prevented by engagement of the plunger with the camform.
