DirkDJ,
If you read the manuals it's all in there, there are no Squat switches there is only Pitot Pressure. Get it up on Jacks and you'll see that the switches make contact even if there is no weight on the wheels required.
The many I have flown don't have WOW switches, only the pressure system. If your one is different then ask a Mechanic to explain what it's for. Because they left the factory without them.
I still maintain that the switches are for the lights, next chance I get I will get one up on the jacks and check them out.
