Right, I assume then they mean something like this (http://www.forge-electronics.co.uk/i...l-10a-rc-relay) but without knowing the context (or the wiring diagram), I wouldn't like to commit to anything.

I've used a single variant of this before on early versions of The Honey Badger 1.0 to power the flail motor but the ones I was using had a horrible habit of sticking open - probably too high a amperage for the switch.
