ABSTRACT:
A switch assembly comprises a push-button switch and a switch operating mechanism including an actuator and a plunger for transmitting the movement of the actuator to the push button to operate the push-button switch. While one end of the plunger is operatively associated with the actuator, the other end of the plunger is rotatably and removably, but axially non-movably, coupled to the free end of the push button. For this purpose, the other end of the plunger is formed with a radially outwardly extending anchor flange while the free end of the push button is formed with a generally U-shaped anchor recess for receiving the anchor flange therein.
