Abstract: The invention concerns a busbar adapter (1) with a housing; contact elements (5), on each of which an electrical connection (12) is formed and which are displaceably arranged in the housing, in such a way that the contact elements (5) can each be displaced between an extended position, in which the electrical connection (12) protrudes outwards in the region of a side face on the housing and by means of which electrical connection (12) an electrical contact to a busbar can be made, and a retracted position, in which the electrical connection (12) is arranged in the housing and the electrical contact is broken; and a single camshaft (9) which is arranged in the housing such that it can rotate and which has an arrangement of cams (10) which, for actuating the contact elements (5), are in each case assigned to at least one of the contact elements (5), in such a way that the contact elements (5) can be displaced in each case between the retracted and the extended position by rotation of the single camshaft (9).

Abstract: The invention relates to an electrical supply connector having a housing, a contact element on which an electrical port is formed and which is arranged so as to be displaceable inside the housing, in such manner that the contact element is displaceable between an extended position, in which the electrical port protrudes out of the housing in the area of a side surface and an electrical contact can thus be made with a conductor rail via the electrical port, and a retracted position in which the electrical port is arranged inside the housing and the electrical contact is disconnected, and an actuating element that is arranged in the area of a front cover surface on the housing and is displaceable between a release position and a coupling position, in such manner that when the actuating element moves into the coupling position it forces the contact element out of the retracted position and into the extended position thereof.
