I have a couple of applications where I need simple and compact local control.
I've settled on a potentiometer and switch arrangement where the pot selects
the desired value and the switch locks the value in and advances to the next
input. I'm about halfway through my testing.

I realized that two separate components are really not necessary. All I need
is a pot with an integrated switch. This would both reduce the space required
for the user interface and simplify the interface because it can then be
operated with one hand without having to move that hand from one component to
the other.

But after searching for a bit I also realized that the commonly
available component doesn't really meet my need.  Common pot/swtch
combos are organized an a volume/power knob type arrangment.  The
switch clicks on/off at one end. What I need is a switch that can be
pushed with the know set in it's current position.

I'm envisioning operation where the interface is activated bu pushing the knob.
The display will flash the value to be set. The knob is turned to the desired
value. Then the knob is pushed again to set the value and advance to the next
one. Once all the values are set the interface is deactivated until the knob
is pushed again.

My two immediate applications are setting the time on my sunrise/sunset
controller and a programmable thermostat I'm putting together. But clearly
it has applications in dimmers and any other kind of control interface where
the switch indicates start/advance/completion and the pot sets the value.

So does such an item exist?

Let me know. TIA.
