Bill of Materials (BOM)

  1. The upper cover of DC reversing contactor is made of BMC material, which features high mechanical strength, good heat resistance (it can be used under 200℃ for a long time) and good aging resistance.
  2. DC motor reversing contactor adopts high-quality stainless steel material.
  3. The contact assembly uses high-quality and high-conductivity copper and silver contacts, which are reliable in contact, more durable and safer and have an electrical life of over 30,000 times.
  4. The DC contactor comes with Teflon magnetic material, 500,000 movements without abrasion, temperature resistance 155℃ and enameled wire.
  5. The base and coil frame are made of reinforced nylon PA66, which has high strength, high temperature resistance, better flame retardancy and electrical properties.


The DC reversing contactor has two sets of switching contacts (two sets of normally open and normally closed contacts), which are used in electric control systems, such as automotive electric winches, telecommunications equipment, construction machinery, battery cars, electric forklifts, trains, ships, uninterrupted power supplies (UPS) and other electronic control systems.

DC Reversing Contactor Wiring Diagram

DC Reversing Contactor Wiring Diagram
KNOWLEDGE BASE --- DC Contactor Working Principle
  • When DC contactor coil is energized (usually with 12V or 24V voltage), the coil current generates a magnetic field, which causes the static iron core to generate electromagnetic attraction to attract the moving iron core, which drives the contact action: the normally closed contact is disconnected and the normally open contact is closed and both of contacts are linked.
  • When the coil is de-energized, the electromagnetic attraction disappears and the moving iron core is released under the action of the "compression spring" to restore the contacts: the normally open contact is disconnected and the normally closed contact is closed.
