Doc , we need you back!

I guess they come in different types- the el cheapo I have here sure looks like a rheostat inside, I very well could be wrong but there is nothing in it resembling any kind of circuit. There is a round device on the back of the switch that looks to me like a common rheostat but I could be wrong and maybe the circuit is inside I will break open that little plastic case and see what is in it, got my curiosity up now.
