Abstract

750,497. Two-part couplings combined with switches. WALSALL CONDUITS, Ltd. Dec. 2, 1953 [Dec. 5, 1952], No. 30864/52. Class 38 (1). In a switch and socket-outlet assembly removal of a plug when the switch is closed is prevented by a plate 14, Fig. 5, apertured for the passage of the earth pin 23 of the plug and arranged to be tilted to bind against the pin by a sliding plate 21 which is moved against a spring 27 by the pin engaging an arm 22 thereof. Actuation of the switch dolly 12, Fig. 3, to the " on " position pivots a plate 35 connected thereto and causes a finger 33 connected to plate 35 to project over the end of plate 21, thereby preventing the return thereof on an attempt to remove the plug before the switch is opened. When plate 21 is in its inoperative position it obstructs the movement of finger 33 and prevents the switch being closed with the plug removed. In a modification wherein the dolly moves at right-angles to the direction shown, the locking finger may comprise a slide which is moved rectilinearly. Specifications 750,498 and 750,499, [Group XXV], are referred to.
