Hi everyone,
Over the years in RC robotics I've used many different RC on/off switches to remotely switch solenoid valves. The best known is the Robbe 1-8445. However, after a while all these have broken down, all due to the relays getting stuck or cracked under the strain of hard landings. I am now looking for a new rc on/off swith, preferably without mechanical relays but something fet based for instance.
This is one of the boards I normally use:
For regular use like in boats or trucks this works fine. But inside our robots even with proper shockmounting they normally don't last more than a year. We normally push 10S lipo @ 5A through that little relay, and they do not like that.
