ABSTRACT:
A latching mechanism for use in a switch such as a push switch comprises a slider capable of sliding in the casing of the switch, a spring for biasing the slider in one direction, and a driving pin disposed in the direction of movement of the slider and acting to move a movable contact relative to fixed contacts. Both ends of the pin are bent such that the pin assumes a U-shaped form. One of these ends is anchored to a hooked element so as to be horizontally rotatable. The other end is received in a heart-shaped cam groove, and is held into engagement with the bottom of the groove.
