ABSTRACT:
An electrical plug and socket connection which has an axially symmetrical plug body, a central aperture in the plug body for receiving a multi-conductor electrical cable and a cylindrical extension secured to the plug body in alignment with the axis thereof which defines a stop surface at the end thereof remote from the plug body. At least one contact ring is disposed coaxially with the extension between the plug body and the stop surface. The contact ring has an exposed outer surface. At least one contact element defined by a radially movable stud secured to one end of a flat spring projects partially into a cavity of the socket portion for cooperation with the contact ring. When the extension of the plug is inserted into the socket the stud and the associated flat spring are pushed radially outward with respect to the axis of the extension into electrical contact with a life terminal of the socket to thereby act as a switch which is closed upon the insertion of the extension into the socket and which electrically connects the contact ring with the life terminal.
