Are switches confused or is everybody else?

[thir]

each to there own is fine by me, i am not here to try and tell the switches what to do, i am only flicking them to see if any lights come on

This joke has only been made about 1000 times

Which is why I would so like to find another expression - "switch" does not really say anything.

"power-shifter"?
"double-bareled"?
"double-edged"?
"binary"?
