ABSTRACT:
The switch includes a case, first and second manipulation members, two switching mechanisms, cam projections two locking members, guide grooves, and an operating member. The guide grooves for guiding the locking members are arranged so that tip ends of the locking members can be put in contact with the operation member for forcibly returning the manipulation members from a pressed-in position to a released position and that the tip ends are prevented from facing the operation member when the tip ends are located in a normal paths of the guide grooves, thereby preventing deformation of locking members and damages of the cam projections due to an erroneous pressing operation.
