PCT No. PCT/GB91/00146 Sec. 371 Date Sep. 18, 1992 Sec. 102(e) Date Sep. 18, 1992 PCT Filed Jan. 31, 1991 PCT Pub. No. WO91/11836 PCT Pub. Date Aug. 8, 1991.An electrical connector, for example a lampholder comprises an on/off switch mechanism including a push bar. The connector further comprises a locking arrangement including an interlock member which extends to the pushbar and moves into and out of cooperation with an aperture in the pushbar. When a cooperating device, for example a lamp, is inserted into the connector the interlock member moves axially into the lampholder to a position at which the pushbar is free to move between "on" and "off" positions. When no cooperating device is connected, the interlock member prevents movement of the pushbar. The pushbar and the interlock member include respective inclined surfaces arranged such that the pushbar will be moved to the "off" position when a cooperating device is removed from the connector.
