Abstract

An ectrical socket comprises a wall mounted faceplate (17) with pin receiving apertures for a plug and an integral (built-in) cover having a cover panel (22) movable between an open position allowing access to the apertures and a closed position concealing the apertures. The cover panel (22) is secured in the closed position by engagement of latch pins (64) with latching means within the faceplate (17). The latch pins (64) are released by a key inserted into keyholes (66) in the side of the faceplate (17) and opens automatically under the biasing of a spring.

2. A socket (or switch) according to claim 1 wherein said at least one cover panel (22;45;98) is movably mounted with respect to a frame (21;42;94) integral with the faceplate (17;41;92) between the closed position, where it completely covers and encloses the faceplate (17;41;92) (and any plug or switch), and the open position, allowing access thereto.
3. A socket (or switch) according to claim 2 wherein the frame (21;42; 94) extends around the marginal edge of the faceplate (17;41; 92).
4. A socket (or switch) according to claim 2 or claim 3 wherein the latch means comprise a catch part (B) engaging with a retainer part (A).
5. A socket (or switch) according to claim 4 wherein one part of the latch means is on or adjacent an edge of the cover panel (22;45;98) and engages with the ether part on or in the frame (21;42;94).
6. A socket (or switch) according to claim 4 or claim 5 wherein one part (A) of the latch means is resilient and can be deflected to engage/disengage the other part (B).
7. A socket (or switch) according to claim 6 wherein the resilient pant is a flexible arm (A).
8. A socket (or switch) according to claim 6 or claim 7 wherein the resilient part (A) is deflected to engage automatically the other part (B) when the cover panel (22,45,98) is moved from the open position to the closed position.
9. A socket (or switch) according to nay of claims 6 to 8 therein the resilient part (A) is deflected to disengage the other part (B) under the control of the key operated release means (D).
10. A socket (or Switch) according to claim 9 wherein the key operated release means (D) includes at least one formation insertable through an opening (66;47;904) in the frame (21;42;94) (to engage the resilient part (A).
11. A socket (or switch) according to claim 10 wherein the opening (904) is protected by a movable shutter (113).
12. A socket (or switch) according to claim 10 or claim 11 wherein the resilient part (A) is deflected to disengage the other part (B) by rotational movement of the key operated release means (D).
13. A socket (or swatch) according to claim 10 or claim 11 wherein the resilient part (A) is deflected to disengage the other part (B) by axial sliding movement of the key operated release means (D).
14. A socket (or switch) according to any of claims 6 to 8 wherein the resilient part (A) is deflected to disengage the other part (B) by an electric actuator (1213).
15. A socket (or switch) according to claim 14 wherein the electric actuator (1213) includes a solenoid.
