How to reverse polarity on a motor. When the timer goes off again at night i want to have a relay that switches the polarity on the motor so the door will close until it hits a low limit switch. In order to invoke reverse motion in our motors the blue and yellow lead wires need to be swapped. Remove the faceplate covering the wiring on your motor using a screwdriver. In case of battery the one pole or plate having more electrons is known as anode or negative terminal. Reversing dc motors requires a specific type of switch namely a dpdt double pole double throw switch center off wired in what is known as an h bridge configuration pictured at right so called because the current flow looks like the letter h when you look at a schematic diagram.
