ABSTRACT:
A control system is disclosed which is capable of controlling N+1 operational modes of a plurality of machine functions of an apparatus utilizing N momentary switching devices in a specific logical interrelationship. The control system includes gate circuit means which is responsive to the N switching devices for latching the control system in at least N+1 operational modes whereby the machine functions are activated and deactivated in accordance with one of a plurality of predetermined operational sequences associated with the operational modes. The N switching devices operate independent of each other yet are interrelated by the gate circuit means to limit the maximum AC line current used by the machine functions during any one of the N+1 operational modes.
