It looks like the Single Rocker Switch # 37213685 will fit your needs. It is a 3-prong switch that has an on/off function. So it will be on when switched to the top and off when switched to the bottom. There would be no 3rd/middle stopping point. Just on and off, but with 3 prongs on the back like you current switch.
