[0002] A DC contactor is a contactor used in a DC circuit, suitable for a programmable power supply or an uninterruptible power supply system, and is used in many new energy fields such as forklifts, electric vehicles, and mobile electric charging piles. When in use, when the contactor coil is energized, the coil current generates a magnetic field, causing the static iron core to generate an electromagnetic attraction to attract the moving iron core, and drive the push rod to move. The push rod drives the moving contact connected to the push rod to move until it contacts the static contact. When the coil is de-energized, the electromagnetic attraction disappears, and the iron core is released under the action of a release spring, restoring the moving contact.
