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 clip ring clutch is used to provide a two-way manual rotation of a ring which carries a ramp that axially indexes the cam.
