    I have a PCB Design which has been tested ok, it just needs re-designing to make it more space efficient. The tracks can be double sided but they need to be done so the PCB can be prototyped with a CNC PCB Mill. Components will be all discrete/through hole type. The PCB Takes a 12vdc Signal to a relay, the relay triggers a shunt coil of an MCCB.
