I would like to take the 240V feed from a trailing edge dimmer that is driving LED lamps and use it also to activate a contactor or relay. This would in turn run a 230V fan.
(Reason: want to have a single dimmer switch controlling bathroom lights, but also have the switch turn the extractor fan on. But don't want to send a dimmed signal to the fan!)
I'm worried that the chopped signal from a trailing edge dimmer may not be what the coil of a relay or contactor needs.
Can anyone shed some light on this, please?
Either, will a relay work just fine on this circuit? Or are some relays more tolerant of what activates them?
