Default Motorized selector switch


I am thinking of building a pre-amp with IR control which will control the volume using an ALPS motorized pot, but I want to be able to change the input using some kind of motorized selector switch. Does anyone know where I can get one from?

A long time ago, computers used "counter" relays for memory. Pulse the coil and it switches to the next state.

Nowadays, the solution is a rotary encoder, a microcontroller, and a multiplexer.
"Fully on MOSFET = closed switch, Fully off MOSFET = open switch, Half on MOSFET = poor imitation of Tiffany Yep." - also applies to IGBTs!
