Yeah I am familiar with how a squat switch works. There’s no suspension in an ASW-20 except the tire so no place to put the squat switch.. I’ll take a look at it when I do the Condition Inspection. Maybe something will come to me.

Can anyone show me the FAA regulation that requires a squat switch in a glider?

You are repeating yourself. I answered this same question from you in the tenth post of this thread. Have regulations change since then?

You may not agree with the reasoning there, I think it's *awfully* written FWTW, but I'm pointing out this is the interpretation used in the avionics industry. I also think it was an bad idea for the FAA to require this for light aircraft and I wish they had left that with the RTCA DO-260 standard of not requiring light aircraft to transmit in ground mode at all (continue transmitting ADS-B airborne messages on on the ground).

Having had a trig 2020 compliant ADS-B out system installed in my Standard type certificated glider, I found the peregrine pneumatic switch elegant, compact, cheap, and reliable. not to mention readily available and acceptable to the documentation requirements.
I also understand the deep desire some have to 'invent a better mousetrap'
Good lift,
