ABSTRACT:
A linear actuator having an actuator member driven in a linear direction by a lever mechanism pivotally coupled thereto which is in turn driven by a plurality of on/off linear drivers. Driving the linear drivers through varying stroke distances provides a sequence of discrete actuator steps. By providing an interconnected simple lever mechanism a discrete set of 2.sup.n steps may be provided for n drive positions and n on/off linear drivers. The linear actuator thus provides simple integration with a digital control system and precise positive discrete steps of linear actuation.
