Abstract
309,714. General Electric Co., Ltd., and Manchester, W. March 23, 1928. Plug couplings combined with electric switches. A latch plate 17, moved by the operating lever 1 of a switch, engages a groove 58 in an earthing-pin 45<a> of a plug when the switch is moved on, thus preventing removal of the plug. Insertion of the plug causes the pin 45<a> to engage a plate 48 and depress a plunger 49 out of engagement with a hole 57 in the plate 17, thus allowing the switch to be closed only when the plug is inserted.
