ABSTRACT:
A toggling type of switch actuator is described in which a pivotable coupling plate is caused to snap away from electrical contact members which it couples together. Action is caused by the depression of an actuator which compresses a spring and moves the line of action of compressive force over center to cause a snap-action motion. Pushbutton actuation is achieved in a very low profile apparatus providing good tactile feel and a self-biased, self-returning, snap-action. The device has only three moving parts.
