Rear Defog Switch

My rear defog only works in the Hi position.  I tested for voltage at the motor and I get 12v in the Hi position and 0 in the Lo.  Pulled the switch out and noticed there are only 2 pins on the back so I thought perhaps one had broken off at some point.  When I searched eBay for a replacement it appears they all have just 2 pins.  Is that correct?

Before I buy a new switch, does anyone know how I can test the switch to be sure?  When I test across the power pin to the Hi pin I get resistance.  When I test across the power pin to where the Lo pin should be I get resistance that is different than across the Hi pin.  Make sense and leads me to believe the switch is working but I get 0v at the motor in Lo.  Maybe the internal power circuit on the switch is broken?

Any help would be appreciated.
