Circuit diagram Notes: Circuits with low-voltage protection will not automatically turn back on when voltage is restored following a power outage. When SCR1 conducts, make the 15V flows through lead K to a positive battery terminal. While in reverse bias the potential difference increases the strength of the barrier which prevents the charge carrier to move across the junction. The same situation is in effect when the reverse coil is energized. 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. In the above 3 phase motor forward reverse wiring diagram. With respect to magnetic contactors, the armature or plunger is the movable part of the magnetic circuit.
