ABSTRACT:
A compact switch device of the present invention includes a casing having a depressible operating member mounted thereon for slidable movement between an inoperative and an operative position. A switch is mounted on the casing and opens and closes in response to the movement of the operating member. The switch device is spring biased to the inoperative position. A cam is mounted on either the casing or the operating member. A locking pin is mounted on the casing or the operating member not already supporting the cam. A closed loop cam groove includes a retaining portion of a generally V-shape and a convex guide portion spaced from and opposite to the retaining portion. The distal end of the lock pin is engageable in the retaining portion to hold the operating member in the operative position. A holder spring is provided to bias the distal end of the lock pin into the cam groove and to urge the distal end toward the retaining portion when the distal end of the lock pin is situated between the retaining portion and the convex guide portion.
