ABSTRACT:
A momentary contact switch is provided having a toggle actuator with the toggle in a normal center-off position. Two different momentary contacts are achieved by pivoting the toggle in either of two directions from its center-off position to one of two ON positions. The toggle returns to the center-off position by spring bias. The spring bias is essentially equal for either ON position and is achieved with a minimum number of parts for such even bias.
