Is this a thermal overload that you can interchange ? (different ratings)
If so, you probably actually have a manual motor starter.
They resemble a switch but have means to add a thermal motor overload heater.

So the thermal overload isnt actually in the switch, the switch is controlling the thermal overload on whatever it is going to?
