Ferg,
Normally, the "squat" switch is located on one of the main landing gear
oleo strut such that the switch is either operated when the weight is on
the gear and the oleo strut compressed. It's primary use is to
disengage the gear retract mechanism when the aircraft is on the ground.
It may have other uses, enabling/disabling things and systems which
should/shouldn't operate on the ground or in flight. It may also
operate a hobbs meter to record flight time for maintenance purposes.
Not having an oleo strut on the Europa Monowheel makes a true "squat"
switch more difficult configure. Perhaps you could do something with
the shock absorber package if you can still get to it. Other
alternatives are a switch operated by the gear retract lever or some
other piece of the gear retract hardware. Or, perhaps, a speed sensing
switch set to around 45 mph.
I had a microswitch located adjacent to the landing gear down-lock notch
so that when the gear lever was in the down-lock notch it opened the NC
contact removing power from a Hobbs meter. Move the gear lever out of
the down-lock notch and the NC elements of the switch closed applying
power to the Hobbs to record actual flight time. Now that I'm a
tri-gear, I no longer have the system operable and will be removing it.
Would you like the Hobbs and switch?

landing......
