An electric socket outlet is provided with an outer shutter (20) mounted slidably on the socket fascia (11) and movable between a closed position in which it covers and hides from view the openings (16-18) in the fascia through which the plug pins enter, and an open position in which the openings are uncovered. The shutter is received in a recess (14) in the fascia so that its front surface is flush with that of the fascia, and is biased to the closed position by a spring (25). A switch may be included and an interlock device provided to prevent the switch being turned on when there is no plug inserted in the socket and to ensure the switch is turned off when a plug is removed from the socket. |
