The switch is no longer available on the physical switch according to manual part number 73682 or CarlingSwitch part number 0333. However, this part matched (after much searching) exactly the rating of the original CarlingSwitch. Incredibly easy exchange. Use a small screwdriver to pry the switch out, align the two wires, and reinsert it. The original switch was red, this one is black. If the switch under the formed word ON is pressed, it's probably best to assume it will turn on when you plug it in.
