Anyone know where to source a 2 way rotary switch.

[tommorichards]

Im making a jazz bass harness for a guy here, but im having difficulty find a 2 way rotary switch to turn his LED's on and off, while being disguised with a knob. Im not adverse to using a 3 way, but does anyone know about a 2 way?

Most rotary switches have a little 'stopper' (a washer with a little prong sticking out of it) underneath the nut which limits the rotation of the switch.
If you just want a minimal on/off swith then just buy a switch with the smallest number of 'ways' and use the stopper to limit the rotation to two positions.


EDIT: Something like this has a stopper... [url="http://www.rapidonline.com/Electronic-Components/Rotary-switches-30304"]http://www.rapidonline.com/Electronic-Components/Rotary-switches-30304[/url]

that could be helpful. I was wondering if something like that was possible. thanks.

What about a 4 way going on-off-on-off.

OR thinking. (Dunno if possible) with a resistor wired in on one setting. the 3 way with off then two differing brightness settings.

Yep - on-off-on-off is perfectly possible.

'Of the shelf' rotary switches generally go up as far as 4 ways and 12 poles - so there's plenty of scope for most types of esoteric switching there.
