I want to actuate a light simultaneously whenever a triac based fan controller switch is on at any setting.
One idea I had was to use a 120VAC coil relay connected to the fan controller output. I only scrath my head cause I don't know if the modified waveform from the triac controller will keep the coil energized no matter the setting? If I had to guess I'd say yes because the max voltage remains 120v at 50/60hz, even if the rms voltage changes.
I suppose I could just buy a relay and give it try but thought I would ask here b4 I go to the effort.
As a clear example I would use this controller with this relay. https://www.amazon.com/Broan-72W-Electronic-Variable-Control/dp/B000UVWWGO https://www.amazon.com/American-Zettler-Power-120VAC-AZ2280-1C-120A/dp/B07587NZTC
the relay contacts at 30amps is overkill for a led light power supply but couldn't find a cheaper one with lower rated contacts (probably only need an amp at most)
alternatively maybe I can just hook up the controller output right to the led light power supply. Maybe the modified wave form won't affect the DC output voltage (12VDC I think) of that power supply.
