I have noticed for a while now that one of our motion switches makes a bit of a pop when it comes on. When I went into the front office today it came on with a loud crack! Not good i suspect. They are probably ancient.
Not cheap things to replace either - £40 plus in most places and very limited choice. Needs to be able to handle 10 tubes say 600W.
Some are sold as 2 wire and others 3 wire needing a neutral. Any ideas which the old ones are likely to be?
