Hi
I've just replaced an old white plastic touch dimmer switch with a chrome one (yes yes it's earthed!)
BUT - When I press the switch I'm hearing a click coming from the CU (as it happens to be in the same room). It's not flicking the fuse off or anything but it's an audible click and I've never heard it make that sound before.
Also whereas the old touch dimmer switch used to buzz, this one doesn't really make any noise but the buzzing noise is now coming from the light fitting. It's loudest when the lights are on full and much quieter when the lights are dimmed - which is the opposite of what the old switch did.
The new switch is a Volex touch control dimmer switch - this one. The light fitting itself is one of those silver ceiling blobs (technical term ) containing a toroidal transformer, with a load of wires with small G4 capsule bulbs hanging off it (7 x 20W). I never noticed buzzing coming from the transformer before; it was always the dimmer switch on the wall that buzzed.
The leaflet that came with the Volex dimmer says:
Suitable for control of dimmable electronic transformers, toroidal (wire wound) transformers and tungsten halogen lamps WITHOUT de-rating.
So if this switch is allegedly suitable then why the loud buzzing and what's that click at the CU all about? Is this switch safe to use or should I remove it?
Thanks.
