ABSTRACT:
In a push button switch with a star wheel having segments with trip cams and being supported in the push button so as to be rotatable about an axis which is normal to the operating direction of the push button, the star wheel is rotated, when the push button is actuated, by an unlatching structure formed on a rotation latch disposed adjacent the star wheel and engaging a projection on the star wheel. The trip cam wheel has cams which operate contact springs disposed adjacent the star wheel along the path of actuating movement of the star wheel whereby contacts are closed or opened depending on the angular position of the cams. Upon release of the push button, the push button is returned by return elements to its original position while the star wheel slides along the contact springs without operating the contacts.
