I need a 25k panel mount rotary potentiometer dual gang, switched when turned all one way so its off then turns if you know what i mean. In the UK if possible please. Thanks
Thanks but i don't have the schematic the idea is all in my head at the moment. I'll have to look into that. I know you can get them all as one as I've got an amp i use with one on although that is mass produced.
They used to be a common standard component, stereo volume control with integral mains switch. However, they seem a bit sparse these days, why not use a separate switch, which is much preferred anyway.
A micro switch with a normally closed contacts (most have both) is another possibility.
Drill and tap a small hole in the flat part of the pot's shaft and insert a screw which rests against the micro switch when the pot' is in the off position.
