Airspeed switch kit for Trig TT31 and King KT74 transponders.
Airspeed differential pressure switch, qty 1 (PA-111114-821)
Clear Poly-Flo tubing, qty 48 inches (PA-111114-825)
Nylon union tee, qty 2 (PA-111114-831)
Nylon insertion stabilizer, qty 6 (PA-111114-833)
Bought for my Rans s9. Not installed as yet.
If there are issues with any switches, Peregrine would like to know so that they can get a no cost replacement out ASAP and also obtain the suspect switch for further fault analysis. Thank you,
Received my switch kit. Installed as the STC states but it failed the pitot static test. The switch leaked which made it U/S. I suspect there are quality control issues with this switch. Mine is going in the trash.
The switch closes at 38 kts.
The STC is not included with this part, but as a component of the unit for which this is used. E.g., the KT74 transponder STC covers this switch.
We have added the install instructions to the web page in the 'Documents' tab. Please download and review it there.
