Title: Switches n' stuff...

Chaps, instead of using two microswitches on a servo to switch a water pump to blow/suck, then suck/blow, is there an electronic switcher available commercially? It seems a waste of an esc just to be able to turn a pump on/off/on.

I am using an Action Twin Relay Switcher in my U-Boat for reversing a water pump, most effective. About the same price as a Viper SC but for pump work on-off is better than slowly ramping up if you knock the stick, especially if you don't notice it pumping!

That sounds as though it'll do the trick nicely...cheers skip, top man.

When you can get a reversible esc for seven quid, why worry?
