ABSTRACT:
The drawings illustrate a double pole, double throw switch for use in selectively controlling energization of either a first or second electric circuit. The switch includes two sets of first, second and third terminals, with each of the second terminals being offset in opposite directions from one another, and a pivotally mounted actuator button. A pair of legs are formed on the inner portion of the actuator button for carrying first and second contact strips, the latter being mounted for universal movement with respect to the second terminals so as to normally contact respective opposite first or third terminals. The legs are moveable in response to initial movement of the actuator button in either direction so as to selectively cause one of the first and second contact strips to pivot overcenter on the second terminal into engagement with the other of the first or third terminals to provide a conductive path between respective first or third terminals and thereby complete one of the first or second electric circuits. The legs are further moveable in response to continued movement of the actuator button so as to cause the first and second contact strips to slide across the respective first or third terminals in a cleaning action.
