It's worth a shot. Could get lucky and just be a lose connection or broken/shorted wire. My car started to do some overheating tricks last summer. I repaced alot more than the switch, but I'm pretty sure that was the culprit. Someone had mangled an early fan switch onto my late 944 and that was most definatly the problem. Mine would either run alot when the car was shut off....like for hours and then it wouldn't kick on enough when the car was running and it would almost overheat every time. I put a new water pump, low temp thermostat and low temp fan switch and didn't have a lick of trouble (with that) afterwards. If you go low temp fan switch I have read that you need to use a low temp thermostat otherwise the fans will be overworked since the thermostat and fan switch would be set for different temps/cooling cycles. G'luck!
