Abstract

A plug and socket assembly comprising (i) a socket that includes a mating means disposed thereon, and an electrical contact on the socket, and (ii) a plug that includes a matching means for mating with the mating means disposed on the socket, and a conducting terminal for coupling electrically to the electrical contact on the socket. The matching means is configured to be adjustable between a compatible mode and an incompatible mode. When in the compatible mode, the matching means allows the electrical contact to contact the conducting terminal, and when in the incompatible mode, the matching means substantially prevents the electrical contact from contacting the conducting terminal.

12. The socket as claimed in claim 5, wherein the abutment is slidable on a guide disposed on the surface of the socket.

13. The socket as claimed in claim 12, wherein the guide comprises a retaining means for reversibly securing the abutment at at least one of a plurality of predetermined positions.

14. The socket as claimed in claim 13, wherein the abutment comprises a flange portion;
