Hi guys I remember those old round switches where my dad worked in the 1980s the place was built in the 50 s so it all makes sense. What I do remember is that when a flourescents lamp was installed to replace a pair of filament lamps in a workshop when switçhing off the switch would break down live to earth with a BANG and blown fuse!

Now that's not what I'd expect from a switch obviously designed with DC in mind!

It was a bit scary when it happened they changed the switch soon after that. I think part of the trouble was that the place was damp which don't help things.

Anyway, I don't really expect it to set anything on fire, with the ceramic base, but I doubt such a switch would qualify as "double-insulated" so if nothing else, I would have a GFI on the circuit.


More to the point in your part of the world: 60W / 240V = 0.25A

True for Anne-Marie but Meezy is located in New York so 120 V is correct!

Well I've repaired all sorts of things, either as necessity or just as a challenge, but I congratulate Meezy on replicating the part I would have considered impossible!
