Abstract
Abstract A mounting assembly for an electrical timing device including a cylindrical receptacle having a plurality of sockets adapted to receive a plurality of electrical terminal pins mounted on the rear of the timing device. The receptacle includes a panel mounting flange disposed about the open end thereof and having a latch member thereon. The electrical timing device includes a dial housing on which is pivotably mounted a bezel. The bezel is provided with a recess so that when the timing device is inserted within the receptacle the recess is gripped by the latch and the bezel then acts as an engaging lever for forcing the timing device into the receptacle so that the pins are properly inserted into the socket. The dial housing has a plurality of gripping members which engage the inner wall of the receptacle when the device is properly inserted. A clamping screw held captive in the bottom of the bezel engages a pivotable one of the gripping members and as the screw is threaded into the member it provides an outward locking force between the inside of the receptacle and the gripping members.
