I wanted an indicator that my parking brake was on within my Primary Flight Display. I used the stall horn limit switch and other parts from that to provide the indication that the parking brake is set.
-This uses:
Aircraft Specialty Bracket (and hoses) and
the Beringer Parking Brake valve, and
Limit Switch and HW from the RV-14 Stall sensor
Printed in PETG, which uses less than 11 grams of filament. I also turning on supports and the base has a path for the limit switch wires to pass through to keep the wires organized and out of the wat of the mechanism.
I could not add this while also selecting the Bill of Materials as all the HW is SAE NAS/Mil spec items. If you're bilding a Van's aircraft and have need ot this, you know what is needed.
