Selecting Micro Switches for UAV Flight-Critical Systems
The UAV Switching Challenge Unmanned aerial systems present a unique combination of constraints for switching components: Extreme vibration from multi-rotor propulsion (10~2000 Hz spectrum) Weight sensitivity — every gram matters on smaller platforms All-weather operation — moisture, dust, and temperature extremes Regulatory requirements — flight termination systems must meet specific reliability standards No maintenance opportunity — switches must perform for the entire mission duration without inspection Standard commercial micro switches were designed for appliances and automotive interiors. They are not qualified for the vibration spectrum, altitude envelope, and reliability demands of UAV flight-critical circuits. ...
