A push-push lamp socket having a socket member (2) into which a conventional lamp bulb (28) can be mounted by a first axial push and released by a second axial push for removal.

A second version of lamp socket (50) has a pair of slots (76,78) in its sides, each having a sloping edge (82) and a resilient snap finger (84) providing tactile and audible signals when the bulb (28) follows cam edges or slopes (96 and 100 or 98 and 102) as it is pushed in, and an outwardly sloping track (88) on the finger (84) for guiding the lug (24) under the force of a connector spring (72) into a latch pocket (92).
