background: putting a rPi in my vintage car, and wanting appropriate looking switches for my vintage. I have the matching key cap / knob caps for my dashboard, but now need to source the right components to mate to those keycaps and connect back to pi, but what switches am I describing?and for 10,000 Points, include link to said component.
So: I need 2 kinds of switches and I'm having a hell of a time here bewildered on digikey and mouser lost in a forrest so hoping reddit comes to the rescue.
Can someone help a) name them and/or b) point me to a link / part number / source? Both should be panel mountable if possible. Both should be slotted shaft if possible (if not, I can cut a slot into them by hand) and both should be 4.5mm shaft diameter if possible.
1 of them should be ROTARY with 3 positions: hi / off / low (for a seat heater pad in a car... sold on amazon by the thousands, but with ugly rocker switches. not appropriate for a vintage car.. but rotary switches with the right knobs from that vintage is why I want to do this). what is the 3 position 12v/2amp hi/off/low switch I need here? what's it called and/or do I have a prayer of finding it with a smooth or slotted 4.5mm shaft (at least 15mm long) panel mount?
The other of the 2 types needs to have 2 states. and therefore could be a push button OR a 2 position rotary switch, but here's what it needs to do: in state 1 it needs to cut power to circuit A and send 12v of power to circuit B (powering up an antenna), and in state 2, it needs to cut power to circuit B and send 12V of power to circuit A (powering up a bluetooth receiver unit). So what is this kind of switch called and how would I wire it? and for a free beer any time you are in portland! send links to both/either with a slotted (preferable) 4.5mm shaft or smooth shaft that is at least 10 - 15mm long (can cut down if longer) and panel mounted.
too much to ask or super common? If you have the above, I'll buy them from you! okay thank you.
