Abstract
A combined pushbutton and lamp for a telephone dial has two housings connected together to form an enclosure for a lamp and a switch. A pivoted pushbutton is mounted on the housings, with a center part over the lamp, pivot members on one side of the center part fitting on pivots or one of the housings and a lever extending on the other side of the center part and actuating the switch. A bezel member snaps over the center part of the pushbutton and holds it assembled to the housings. The lamp extends up into the center part of the pushbutton which has restricted movement, the lever amplifying this movement to actuate the switch.
