Abstract

Improved lampholder, characterized by the fact of consisting of three main parts that are assembled successively with each other so that the central is hidden by the other two, one of which has the cylindrical configuration of internal thread suitable to receive the lamp, while the other has the shape of a dome, with its pole crossed by a hole through which passes an interior piece that protrudes outward into a slotted stem so that it can be easily rotated, for the operation of a switch arrangement incorporating said lampholder, said switch is constituted by the rotating assembly and the series of sawtooth contacts located in the concealed intermediate part, the dome configuration having a recess intended to constitute, through two holes in its base, the passage for the electric conductor, also presenting two other side holes for access to the tightening and loosening of the screws s of the terminals for securing said conductors and which are incorporated in said concealed intermediate part, all in such a way that the outgoing actuating rod of the switch can be rotated in the appropriate sense so that its internal arrangement, incorporating a elastically mounted pin, jump from the closed circuit to the open circuit position, but it being impossible to rotate said arrangement in the opposite direction because there is a ratchet coupling between the outgoing part and the inner part.
