Hello
I unearthed from the bottom of the drawer a dimmer switch dating no doubt from the beginning of the 80's. A big rotating button and an on-off switch. What surprises me is the fact that you just insert it into the phase line, ie you don't need phase + neutral.
It has a 500k lin pot, 3 largish caps, a thick wire coil wound onto a piece of ferrite rod, and 2 or 3 res and diodes I can't see clearly. It still works and it is very quick and simple to modify light intensity.
Just for curiosity, does anyone have an idea of the priciple of how it works?
Thanks
