The working principle of the contactor is: when the contactor coil is energized, the coil current generates a magnetic field, and the generated magnetic field causes the static iron core to generate electromagnetic attraction to attract the moving iron core, and drives the AC contactor to move, the normally closed contact is disconnected, and the normally open The contacts are closed and the two are linked. When the coil is de-energized, the electromagnetic attraction disappears and the armature is released under the action of the release spring, the contact is restored, the normally open contact is opened, and the normally closed contact is closed. The working principle of DC contactor and the principle of temperature switch have
