<p>The outlet comprises sockets which are maintained in an isolated state as long a connecting plug of application equipment is not completely inserted into the outlet. For this purpose switches (6,7), actuated by the conical surface of a sliding part (18) which is itself actuated by the base (39) of the plug (30) after the contacts (31 and 32) have been completely inserted in the sockets (28 and 29), provide the energisation of the sockets (28 and 29). Thus any arcing between contacts and sockets is prevented. The switches (6 and 7) may also be arc-proof devices. <IMAGE></p> |
