I'm interested in a toggle switch that can be toggled without user input. That is, the physical state can be toggled electrically. It would need to incorporate some sort of motor or magnetic actuator. My google-fu is weak in this area, and I haven't been able to come up with the correct combination of search terms.
Note that I'm not talking about a relay; I'm talking about a normal toggle switch:
Except that it can be toggled without user input. As in, the lever physically moves. Like a "useless machine" except that the mechanism is internal to the switch.
