I am trying to switching both the ground and hot on a skid steer attachment motor(12 vDC) to change direction of rotation. Joystick has two buttons to turn CCW and one for CW to move chute on snowblower. Each button actuates a relay running power out to attachment on a single wire. I believe(?) I need two DPDT relays mounted ON the attachment to take these two outputs and run motor in either direction to accomplish task.
It seems the easy way to do this is with a pair of DPDT automotive relays. Can’t seem to find that flavor . . .?
It appears SPDT relays are easily available, but DPDT are "UN"obtainables? Why or am I just a confused Mech. Engineer?!
