摘要： An electrical rocker type wall switch capable of single, duplex and triplex configurations incorporates one or more slightly concave manually depressible rockers. These rockers have a relatively short range of motion from their respective on to off positions. The edges of the rocker lie substantially flush with the switch cover when in either of their on or off positions. Switching is actuated by an actuating arm attached to the rocker moving a contact on the end of a movable brush arm in and out of electrical contact with a fixed contact on the end of a contact arm attached to a fixed terminal. One or more brush arms extend from a fixed brush backplate and are formed so as to be resilient. Switch toggling is achieved by using a toggle spring, held in place on the end of a toggle arm, which is compressed during the first half of travel of the rocker from its resting position and expands as the rocker crosses its midway point toward the second half of travel to its resting position on the other side of the switch. The toggle spring sits centrally over a spring pivot which has two spring stops on either side of it to support the toggle spring at the on and off position of the rocker.
