Abstract
The present invention relates to a lighted electrical pushbutton switch which may be utilized with only slight modification to switch either one or two normally open circuits. The movable contact member comprises an octagonal-shaped plate that carries at least two pairs of deflectable contacts and a pair of guide wings. The movable contact may be modified for two circuit operation by dividing the contact member into two sections and by providing an insulating support member. The actuating pushbutton for the switch is formed with four downwardly depending legs which contact the movable contact on its upper surface while a return spring contacts the movable contact on its lower surface. The stationary contacts for the switch are supported across the interior corners of the switch thereby providing contact surfaces for the deflectable contacts of the movable contact as the actuating button is depressed, which yields a predetermined 'feel' characteristic.
