What if the switch was lighted? If a dimmer was present, could I use it safely? https://drive.google.com/file/d/1Z06syak1-pMNNdQyTMr0UDEztbMyEV9i/view?usp=sharing
TRIAC dimmers have been around for quite a while, my mother has a 30+ years old one for her dining room. You wouldn't have a 500+W rheostat or variac in a standard electrical switch/outlet box.Depends on the dimmer. Older ones would be rheostats or variacs (which were bulky).
Is the dimmer just a potentiometer? If so, I can use it to adjust fan speed. I am running 12V DC through the switch.A bit confused. Are you wanting to run 12V through the wall switch? Seems to be what your drawings indicate.
Or do you mean to have the 12V supply switched on and off by the wall switch? That would be okay.
You can't have a power supply hooked up to a dimmer, no. Most power bricks are 100-240V, so when the dimmer drops below 100VAC it would shut off.
