ABSTRACT:
The lamp socket according to the invention demonstrates a housing (2) with a rotor (26). Contacts (15, 16), which demonstrate contact tags (17) that are resilient in the swivel direction, are mounted in the housing (2). The open ends (18) of the contact tags can support themselves on stopping means (31to34), which are moved by the rotor (26). In the support position, they are positioned on the ends (18) of the contacts (15, 16). When the lamp is rotated from its insertion position into its connected position, the support means (31to34) are distant from the ends (18) of the contacts (15, 16), however, so that the lamp can be rotated relatively freely without current. Only near the end of this rotational movement do cams provided on the support means (31to34) bump against the ends (18) of the contacts (15, 16) and force them radially inwards and clamp the contacts (15, 16) against the pins (45, 46) of the lamp.
