Digital potmeter with on/off switch?

Hello Folks,

Is there any device that can not only perform digital potmeter action with up/down rubber buttons but also replace the power switch? Ideally suitable up to 20V, automotive or so. However, that 20V could possibly be done via some regulator.

I am looking into replacing a switch/potmeter combo. It is 1M but lower values are ok. Main thing is that the whole setup does not consume more than a few uA in the switched off state.

I know that all this can be accomplished with a uC but this is meant for a quick demo.

Regards, Joerg
