I'm new to this but have a question about this topic. I have two 12 v DC motors in the same circuit that need to be able run forwards and backwards simultaneously. My current set up is a DPDT switch - center off, up and down for different directions - going through two SPST relays with a diode across two of the terminals to prevent current flow in the wrong direction. I also need two microswitches to prevent movement beyond a certain point in each direction on one motor which cancel the entire circuit. Total circuit load is 10 amps max. (fuse value). Question is, as long all the parts are rated at >10 amps (e.g. switch, etc) can I replace this set up with a DPDT switch wired to reverse polarity or maybe a switch running a DPDT relay?
