ABSTRACT:
An electrical plug comprises a plug body which houses two or more electrical terminals for connection to electrical cables, at least one of the terminals being conductively connectable and disconnectable from its respective contact pin. To achieve this, the plug body is provided with a tumbler switch, operable to effect electrical contact between a spring contact permanently conductively connected to the contact pins and the terminal by means of a pivoted lever normally biassed out of contact with the terminal by means of the spring contact. The rocker of the switch may be operated manually, but manual operation will be over-ridden on insertion and withdrawal of the plug from its complementary socket. The automatic switch control means comprises an axially slidable pin projecting from the plug body in the "switch on" position and retractable into the plug body on engagement of the axially slidable pin with the front face of the complementary socket, to urge the switch into the "off" position. The free end of the pin may be provided with a cam surface for cooperation with the socket on rotational withdrawal of the plug from the socket, to switch the plug off on withdrawal as well.
