Low cost magnetic held switch
Description
#Magnetic Held Switch Custom made (3D printed case, tractor and bat), low cost magnetic held switch. This thing connetcs a **modded three way switch to a solenoid**. The mechanism can be controlled by a microcontroller (pscockpit main board in my case). Magnetic held switches allow to have a switch which comes back to the center position when a command (from a flight simulator, for example) is received. ##**Application examples:** >✓ F-16 Landing Gear Panel : parking brake switch (if in parking position, and engine RPM goes above 80%, parking brakes are automatically disengaged to preserve brakes). >✓ F-16 Miscellaneous Panel: Attitude hold, Altitude hold switches. Autopilot may be disengaged if for example LDG is extended, Stall, AoA above a limit, refuelling door is open ... ##**Components list:** >✓ [3 way Toggle switch](https://es.aliexpress.com/item/4001045210896.html?spm=a2g0s.9042311.0.0.274263c0eVjCRP) >✓ [Small, 15N 12VDC solenoid](https://es.aliexpress.com/item/10000013465022.html?spm=a2g0s.9042311.0.0.48a963c0T78UJ4) >✓ [5V relay protection board](https://es.aliexpress.com/item/4001028551700.html?spm=a2g0s.9042311.0.0.274263c0DbIeJP) >✓ [5A 400V diode (for the 12VDC solenoid)](https://es.aliexpress.com/item/32673321261.html?spm=a2g0s.9042311.0.0.274263c0DbIeJP) Take a look to the video of the dry run of the switch : **https://youtu.be/exI2VsxZdDE** ##**More info on the project** **https://giovannimedici.wordpress.com/2021/06/13/low-cost-magnetic-held-switch/**
