I have recently replaced a double socket that had a short circuit fault on the right hand socket with a new one from B&Q. After long periods of use the right hand switch refuses to stay off. If I turn it off it will just spring back on by itself. After a couple of days I replaced the socket with one of the same model and the new one is doing the same thing on the same side.

I'm no qualified electrician but I am competent and it was a straight swap of wires so pretty sure it hasn't gone wrong.

Any ideas as to what it could be? At first I thought a faulty socket hence the replacement but seems odd that the second unit is doing the same thing. Thanks in advance

Edit: Here is a link to a video clip that shows the problem. https://www.dropbox.com/s/a2coson85m3z7e2/Video%2011-04-2016%2019%2014%2051.mov?dl=0

  • Could be a faulty design or batch. – Someone Somewhere Apr 11 '16 at 23:15
  • Is this a socket with a built-in knob switch? If so, then perhaps the knob's axis is being pushed off-center by the fixture? (A picture would really help.) – Daniel Griscom Apr 11 '16 at 23:38
  • In the UK every receptacle outlet has a small switch right next to it, i.e. a duplex receptacle has 2 switches. If that seems overkill, don't ask where they put fuses! – Harper Apr 12 '16 at 5:06
  • When you physically mount the socket, is the mounting surface smooth and flat? Are you putting a lot of force on the screws when you mount it? I wonder if something about your mounting is bending or damaging the socket in a way which is causing this. Or your particular usage is pulling the limits of current, and it's cheaply made. Obviously a third of the same model will do the same thing, I'd go up to the next better one. In the US I'd say use the $4 outlets instead of the 60 cent outlets. – Harper Apr 12 '16 at 5:11
  • Thanks for the advice so far. Tempted to say faulty design but its a fairly standard piece of kit I would have thought? @Harper - There doesn't seem to be any massive amount of force when screwing into the back box so I don't think its bending the face plate at all. If it is then its very weak. – James Apr 12 '16 at 16:28

If the two sockets were bought from the same branch of B&Q i'd bet on a faulty batch, possiblly combined with a marginal design. My advice would be to return the socket as faulty and replace with one of a different brand.

  • I think that might be the answer. I will take it back when I get chance and get a different model. If that is the case then I shall mark this answer as correct. Thanks in advance – James Apr 13 '16 at 7:29
  • Can't actually find the receipt now which is annoying but that shouldn't stop an accepted answer on here. Thank you – James Apr 26 '16 at 23:09
