When applying voltage to the coil, the electromagnet is excited and the moving core is attracted to the fixed core,
then moves in the direction of the arrow. The moving contact linked to the moving core com es into contact with
the fixed contact and closes the circuit. Then, cont act pressure and cont act over travel are applied to the contact
by means of the contact spring.
When releasing the excitation of the coil, the moving core is separated from the fixed core, and the moving contact
parts from the fixed contact, and opens the circuit.
