Overview

Universal Switch Airspeed Kit (USW-1) allows the control of electrical loads based on airspeed. The airspeed set point is factory calibrated to 100 knots, however, it may be field adjusted to switch at any speed between 55 and 140 knots. The Universal Switch-SPDT controller provides both a normally open and a normally closed contact for controlling any electrical load up to 10 amps. This allows electrical loads to either be on or off, above or below the airspeed set point. The system works with aircraft power systems from 10-30 volts.

Installed in my Lancair 360 to prevent accidental gear retracting on ground or below 90 kts. Installs easy and works well.
