Abstract
Disclosed herein is a push-rotation type key switch device which consists essentially of a lock main body having a rotor which is not capable of sliding in an axial direction, a switch fitted to the rear of the lock main body and a switch operating cam caused to slide backward in the axial direction of the rotor when a key is inserted into the rotor. When the cam is rotated integrally with the rotor in either normal or reverse direction, the switch is turned on and off.
