ABSTRACT:
This disclosure is directed to a switching device for a coin controlled machine in which the device is actuated in response to completion of a predetermined number of cycle of an operator member. The device includes a shaft disposed for rotating a predetermined angular increment each time the operator member cycles. The device includes a first cam and a second cam adjustably positioned on the shaft relative to each other to permit selecting a predetermined distance along the camming surface of the first cam between the initial inoperative position of said first cam and its actuation position. The angle subtended by the selected predetermined distance along the camming surface of the first cam is a multiple of the predetermined increment that the shaft rotates each time the operator member cycles. The arrangement is such that the selected position of the second cam relative to the position of the first cam will determine the number of predetermined increments required to advance the first cam to its actuation position thereby requiring a corresponding number of cycles of the operator member to effect activation of the coin controlled machine.
