ABSTRACT:
A linear motion switch assembly suitable for a set switch of a vehicle automatic speed control contains two cam operated switches which are actuated in a specific sequence, i.e. the first switch and then the second switch is actuated upon the movement of the actuator in one direction and then the first switch and then the second switch is actuated during the opposite direction of movement of the actuator. To accomplish this, a cam fixed on the actuator operates one of the switches but a second cam connected to the actuator by a lost motion connection operates the second switch. The actuator is a reciprocating element guided along a guideway molded in the switch housing and the switch elements comprise a leaf spring fixed at one end to a circuit board and the other end free to move toward or from a stationary contact also on the circuit board.
