Electromagnetic relay from the core, coil, armature, contact reed and other components. As long as the voltage applied at both ends of the coil, the coil will flow through the current, resulting in electromagnetic effect, the armature will be attracted by the electromagnetic force to overcome the return spring tension suction to the core, thus moving the armature Point and the static contact (normally open contact) pull.

When the coil power, the electromagnetic suction also disappear, the armature will return the reaction of the spring, the moving contact and the static contact (normally closed contact) pull. Pull, release, so as to achieve the conduction in the circuit, cut off the purpose. Relay "normally open, normally closed" contact, to distinguish: the relay coil is not energized when the static contact is disconnected, known as the "normally open contact"; static contact is called the "normally closed contact point".
