I am designing a failsafe system for an Unmanned Aerial Vehicle, and it needs to be able to switch 6 PWM outputs from one source to another. My initial thought was to use a series of logic level relays but they cannot fulfill all the requirements that I have listed below, what are some alternative methods I can use?
- Survive intense vibration (~.3G at 300-600Hz)
- Fail safe, in the event of a total loss of power the signals will flow without impediment
- Listed MTBF or MCBF (hoping for around 1,000,000 Hours or 100,000 Cycles per channel)
