There are 10 - the one I took out was a 50W one. So i would presume all the others are 50W. The one I put in was 25W. They didn't come on - only the one again - after I changed it. They were on - I put in the new one - they were off - put in the old one - still off - put the new one back again - still off apart from one. Now they've come on by themselves again - all 10.
It could be overloading the switch at 500W, thats over 2Amps
It worked ok for about 10 days after moving. Tonight leaving the switch on they all come back on after a while - at least it's happened twice. When I turn the switch on and off now they are all working.
perhaps a poor connection in the switch?
Why would it fix itself on it's own do you think? it seems odd that it's always the same one that comes on by itself - and then they fix themselves. For a while.
A loose connection could do that, does the switch get warm?
Not that I've noticed. Its' got 4 other switches on it.
