John Bitzer wrote an email to os with a wish for a switch ready to use in F5J competition gliders. Signal passthrough for Speedcontroller and redundant functionality, were some of the wishes. The final result can be seen below. Light, strong and super reliable.
Dual Battery Magnetic Switch 20A
Designed for large scale RC gliders, where safety is a key component. Small and super reliable, due to it’s redundant function. Incredible strong, tested with short current burst of more then 200A.
David has a simple and smart solution for not forgetting the magnet.
