Abstract

A safety lampholder for receiving a bayonet bulb, the lampholder comprising a body defining slots each of which has two mutually inclined limbs along which the bayonet pins of a bulb slide during insertion and removal of the bulb, a contact carrier mounted within the body and movable relative to the body between first and second positions, power supply terminals supported by the body and defining surfaces facing the carrier, direct access to the terminal surfaces being obstructed by the contact carrier, and contacts supported by and extending on both sides of the carrier. The contacts move with the carrier so as to be spaced from the terminal surfaces when the carrier is in the first position and so as to bear against the terminal surfaces when the carrier is in the second position. The carrier comprises a sleeve extending to the body slots and defining slots for engagement with the pins of an inserted bulb. The body slots and sleeve slots are arranged such that as a bulb is inserted its pins slide along one limb of the body slots and enter the sleeve slots and then slide along the other limb of the body slots whilst bearing against the edges of the sleeve slots so as to rotate the carrier with the bulb to the second position. As a bulb is removed its pins slide along the said other limb of the body slots whilst bearing against the edges of the sleeve slots so as to rotate the carrier with the bulb from the second position and then slide along the said one limb of the body slots and out of the sleeve slots to leave the carrier in the first position.
