I'm looking for small plugs to connect a motor to a regulator. Can a 3.5mm mono jack handle 600mA? Do you know of any other options? It has to have 2 contacts at least, easy to attach and the connectors have to be easy to obtain.
The power connectors usually found on the end of wallwart power supplies would be better. A socket for the 2.5mm type is shown in This Link , which can pass 6A. They should be available locally though.
