The working principle of the power production contact is: when the contact coil is energized, the coil current generates a magnetic field, and the generated magnetic field leads the static iron core to produce electromagnetic attraction to the iron core, and drives the AC contact action, the normally closed contact is disconnected, the normally open contact is closed, and the two are connected to each other. When the coil is de-energized, the electric ...
