Abstract

A lampholder or other bayonet socket has a shutter 3 that is rotated with a cooperating lamp or plug on removal, to cover the socket contacts 2. The shutter carries conductors 4 for interconnecting socket terminals 2 with terminals on a plug. A shutter lug may extend through the socket casing to provide a switch lever. <IMAGE>
