ABSTRACT:
A cam is axially displaced so that a pair of cam followers sequentially drop from the cam's outer periphery to sequentially close a pair of electrical switches which are responsive to the cam followers. Upon completion of a program, the cam is permitted to displace to its original position. A coil spring clutch permits an actuator to be located in a predetermined position for axial displacement of the cam.
