Abstract
An electrical safety socket in which the neutral and live socket outlets are electrically isolated until substantially parallel pins of a two- or three-in plug are inserted therein. The neutral and live socket outlets are resiliently biased 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 to impinge on a switch assembly, thereby closing neutral and live switches connected between the live and neutral feeders and the respective socket outlets. Also disclosed is a safety lamp socket having a split collar which is splayed apart upon insertion of a lamp. Armatures attached to respective collar components are thereby pivotally displaced about pivots fixed to the socket housing, opposite ends of the armatures impinging on neutral and live switch contacts so as to close the corresponding switches and connect the neutral and live feeders to the respective socket outlets.
