<p>A programmer for controlling the actuation and deactuation of a plurality of load function switches. A motorized cam drum track moves a follower pivoted about a fulcrum pin. A solenoid controlled by a microcomputer moves a slidably bar operable to selectively latch and unlatch the fulcrum pin. When latched, the pin causes the follower to pivot and effect the actuation and deactuation of the associated switch in response to the cam track and the follower, when the fulcrum is unlatched, leaving the switch unmoved. The solenoid controls latching and unlatching independently of the cam drum rotation. <IMAGE></p> |
