pull cord dimmer that doesn't leak ?
just fitted a dimming pull cord lightswitch in the bathroom but after much
head scratching as to why the fan wouldn't switch off after X minutes I found the switch leaks, 24v to be precise, and it doesn't despite. the LV lights don't work with that voltage but it's enough to keep the fan running as it's the switched live. anyone know a solution or supplier of a switch that doesn't leak ? thanks |

What sort of transformer for the LV lights? Electronic or normal? If electronic, changing to a wound one one should do it (but make sure it's suitable). Or add a relay. The fan voltage sensor must have a high input impedance so is sensing at near zero current. -- *I wonder how much deeper the ocean would be without sponges* Dave Plowman London SW To e-mail, change noise into sound. |

The fan voltage sensor must have a high input impedance so is sensing at near zero current. transformers are electronic, but the fan isn't on a transformer, it's 240v the switch isn't suitable for wound transformers just bought a replacement from TLC, as suggested by Sparks, but it's the exact same switch just in a different box back to the drawing board... |

A wound transformer would shunt the leakage from the dimmer to neutral. A suitable resistor across the electronic transformer input might well do the same thing. -- *I'm pretty sure that sex is better than logic, but I can't prove it.
