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.

Q: At what airspeed will this Peregrine Airspeed switch close? (kts)

The switch closes at 38 kts.

Q: Does the STC come packaged with the switch?

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.

Q: Is there a wiring diagram somewhere for the Peregrine Airspeed Switch?

We have added the install instructions to the web page in the 'Documents' tab. Please download and review it there.

Q: What voltages does this switch support or is it supposed to be operated as a ground open/close?

This runs on airflow not voltage, the switch closes at 38 knots.

Q: When it is switched on by airspeed does it support a specific voltage range or is it a ground only switch, IE it switched something on when it reaches 38k how much power can it support?

This will work for both 12 and 24 volt system.

Q: What is the diameter of the static and pitot inputs? 1/4?

0.200" they can be used with 1/8-3/16 tubing.
