Specification
Brand : FENOKD
BulletPoint1 : This product is used for middle school physics teaching to understand and study the basic structure and working principle of electromagnetic relay.
BulletPoint2 : This product can be used with other instruments to perform demonstration experiments such as automatic control and remote control.
BulletPoint3 : This product is mainly composed of electromagnetic syand contact system. The electromagnetic syincludes: electromagnetic coil and iron core armature; the contact syincludes: a pair of normally open and normally closed contacts.
BulletPoint4 : When the coil is energized, the iron core generates magnetism, sucks down the armature, disconnects the power supply of the coil, the iron core loses magnetism, and the armature resets, thereby controlling the controlled circuit.

Instructions
1. Equipped with 9V DC power supply, and can also be equipped with other controlled instruments (such as indicator lights, demonstration motors, etc.) for demonstration.
2. Close K4, control the current through the electromagnet M to generate magnetism, draw the armature P down, make the controlled circuit contact K3 contact, the normally open circuit is connected, disconnect K4, the current disappears, the electromagnet M loses its mag , and the spring B pulls up the armature P, the normally open circuit is disconnected, K2 contacts, and the normally closed circuit is connected.
3. Turn the spring screw on the iron to make the spring expand and contract, so that the normally open and closed contacts are in good contact.
