ABSTRACT:
The follower tip of the switch operating bell-crank lever can ride on the large diameter of the axially movable, rotatably driven cam or on axial movement of the cam can drop onto the smaller diameter of the cam to close one switch and, upon further axial movement, the follower can move further in to a pseudo inner diameter to close a second switch. The lever acts to prevent return axial movement of the cam until the cam notch is aligned with the follower and the follower no longer interferes with axial movement.
