Abstract
A switch assembly includes switch contacts, a snap action type switch actuation mechanism, a cam block having a cam surface which is engaged by cam follower, and a manually movable push button. Upper and lower force transmitting pins extend in opposite directions from the cam block to a push button and the snap action mechanism. The cam block and force transmitting pins are integrally formed as one piece. The upper force transmitting pin is connected with the push button by a snap connection. The switch actuation mechanism includes upper and lower actuator members each of which has a main section and a pair of bearing sections. The main sections and bearing sections of each of the actuator members are integrally formed as one piece.
Claims13
An assembly comprising a housing, switch contacts at least partially disposed in said housing and operable between actuated and unactuated conditions, a switch actuation mechanism at least partially disposed in said housing, said switch actuation mechanism being operable between first and second conditions to effect operation of said switch contacts between the actuated and unactuated conditions, a cam follower at least partially disposed in said housing, a cam block having a cam surface with a first portion which is engaged by said cam follower when said switch contacts are in the unactuated condition and a second portion which is engaged by said cam follower when said switch contacts are in the actuated condition, a manually movable push button, a first force transmitting pin extending between said push button and said cam block to transmit force from said push button to said cam block, and a second force transmitting pin extending between said cam block and said switch actuation mechanism to transmit force from said cam block to said switch actuation mechanism, said cam block and said first and second force transmitting pins being integrally formed as one piece.
An assembly comprising a housing, switch contacts at least partially disposed in said housing and operable between actuated and unactuated conditions, a switch actuation mechanism at least partially disposed in said housing, said switch actuation mechanism being operable between first and second conditions to effect operation of said switch contacts between the actuated and unactuated conditions, a manually movable push button, said manually engagable push button includes a plurality of light sources which are connected with said push button for movement with said push button relative to said housing, a force transmitting apparatus extending between said push button and said switch actuation mechanism to transmit force to said switch actuation mechanism, and a printed circuit connected with said switch contacts and said light sources, said printed circuit includes a flexible portion which is deflected by movement of said push button, said flexible portion of said printed circuit includes an opening through which said force transmitting apparatus extends.
