An electrical safety socket (15) in which the neutral and live socket outlets (22-24) are electrically isolated until substantially parallel pins (11-13) of a two- or three-pin plug are inserted therein. The neutral and live socket outlets (22-24) are resiliently biased (42, 43) into a non-parallel disposition such that insertion of a plug into the socket rotates them into a mutually parallel orientation, at the same time causing laterally disposed abutting means (40b, 41b) to impinge on a switch assembly (30-32), thereby closing neutral and live switches connected between the live and neutral feeders (50, 51) and the respective socket outlets (22-24). Also disclosed is a safety lamp socket (100) having a split collar (112a,b) which is splayed apart upon insertion of a lamp (118). Armatures (113a,b) attached to respective collar components are thereby pivotally (115) displaced about pivots (114) fixed to the socket housing, opposite ends of the armatures (113) impinging on neutral and live switch contacts (107a, 109a) so as to close the corresponding switches and connect the neutral and live feeders (106, 108) to the respective socket outlets (101, 102). |
