Abstract: An electrical plug and socket having electrical contacts that are magnetically retained to the counterpart electrical contacts, where the electrical contacts may be optionally be mounted for translational movement, optionally including a sprung carrier arranged to provide a counter-force to at least one direction of translational movement.

Abstract: A plug (1) for electrical equipment comprising a housing (9) and two electrical pins (4, 5) extending from the housing for receipt by a socket and for electrical connection therewith, and the plug further comprising an electrical contact (3) also arranged for electrical contact with the socket, wherein the pins are longer than the electrical contact, wherein the projections arranged to facilitate disengagement of the plug from a socket, and further wherein the electrical contact arranged to magnetically attract to the socket and thereby provide a magnetic retaining force between the plug and the socket.
