It can go wherever.

But key thing is there is this switchboard with a bunch of switches one
for kitchen, one for hall etc. Then you walk to each of them and toggle
them.

So there are basically two commands - one to walk to next switch and one
to toggle it.  Switch themselves report whether they are ON/OFF and
IN-FOCUS/OUT-OF-FOCUS.  Choice of switches themselves become immaterial.

If one wants a new control then all one has to think about is what
character or glyph it will take and add it to the switchboard.
