Hi all, possibly stupid questions follow which may have been posted before, apologies if this is the case. I have saturn wireless switches which we retro fitted into our house some 6 odd years ago now. When we did it we found that they were not very good for fan control (probably more the idiot (me) programming them) so also added at the time a relay unit and some wired switches for fans and non dimable lights. Both of these are bridged together so that all lights and fans can be controlled in some fashion. Anyway, what I'm finding is that when a bulb blows (i.e. pops rather than a simple die piecefully and dont turn on) in one of the downlights on a circuit, the switch itself gets blown, and as a result we have to replace the switch as well as the bulb. Furthermore when this happens the remaining downlights on the circuit remain on, and in a dimmed fashion, so to turn them off until I get a new switch I have to physically remove the switch. Having just removed my fourth switch its starting to irk me. So my question is, why does the blown bulb blow the saturn wireless switch? Is there something that I need to do to isolate the switch or do I need to have specific downlights or something special functionwise in the downlights to stop them blowing the switches? Appreciate any thoughts as to what might be done to save the reamining switches from the fate of the others. Lawrence
