ABSTRACT:
A lamp socket assembly adapted for use with a printed circuit. The lamp socket assembly of the invention includes a tubular socket portion which receives and retains the lamp and which also is attached to a base member in a conventional manner. The tubular socket portion also includes a plurality of longitudinal flanges which cooperate with corresponding notches in an aperture in the printed circuit board to allow the socket to be locked onto the printed circuit board by inserting it and twisting it. The novel feature of a lamp socket in accordance with the invention lies in the inclusion of a resilient ring around the tubular socket portion which provides a biasing force to urge the socket away from the printed circuit board so that the frictional engagement of the flanges and the printed circuit holds it in place.
