Abstract
A cup shaped hub has an actuator rim at its open end and is rotatably carried on a shaft through an aperture in its closed end. The hub is axially fixed to the shaft such that when the shaft is axially displaced the actuator rim opens and closes a line switch. A ratchet is carried by the shaft and is axially spring biased by a coil spring disposed between the cup shaped hub and the ratchet. A pin carried by the shaft engages the ratchet such that the ratchet may be rotated and axially displaced with the shaft. A coupling means couples the shaft to a cam means rotatably carried by the shaft and the cup shaped hub and includes teeth engaging the ratchet means such that a manual rotation of the shaft provides manual rotation of the cam means.
