Don't ask me why, I'm a gadget enthusiast and have the above equipment, and don't fly anywhere near flarm equipped gliders.

Thanks, and Happy New Year!

Just some FYI. The installation diagram for the Peregrine airspeed switch depicts that it is in the 'low' or open condition when airborne (34 +/- 3 kts), and does not appear adjustable. The ASW-2 switch described from Aircraft Spruce ($47.50) is adjustable from 10-55kts; it is not intended for certified aircraft, which could be an issue for STC folks.

I just bought and installed this ASW-2 switch. It is Normally open until triggered by the appropriate pressure differential. The TrigT22 can be configured for either a high or low input. The switch is preset for 40 knots, but my testing showed it to be closer to 80 knots. Adjusting is easy. Use a syringe to (carefully) pressurize the Pitot until your ASI reads 40 knots (or whatever you wish). Then adjust the switch with a small screwdriver until the ADS-B out switches from ground to air. Done! Check the transition point with the syringe to insure its right.

I am looking at the peregrine diagram right now, and done a continuity test, Charlie is correct, open circuit when pitot pressure above threshold, closed when no differential pressure present, so trig setting would be low when airborne.
Thanks,
Scott

The point of my previous post was the circuit diagram on the peregrine box seems to show pitot pressure closing the circuit, testing shows the opposite, pitot pressure opens circuit.

I just installed this switch, and it is Normally Open. One side connected to ground, and the other to the "SQUAT" input on the Trig. When "SQUAT" is grounded, trig goes into airborne mode.
