ABSTRACT:
An improved light socket for use with light bulbs of conventional design and threaded base, has a frame and a cup adapted to accept the light bulb base mounted for longitudinal motion within the frame between a first extended position and a second retracted position. Electrical contacts are provided for establishing electrical continuity with the bulb, the contacts being engaged with the bulb when the cup is in the second, retracted position and disengaged from the bulb when the cup is in the first, extended position. An engagement finger engages the bulb thread when the cup is in the retracted position to retain the bulb in the cup, and releases the bulb when the cup returns to the extended position.
