1. Electromagnet: The electromagnet of high and low voltage relay is usually composed of two parts: coil and core. When the high and low voltage relay inputs the electrical signal, the electromagnet coil will generate electromagnetic force, drive the iron core, and realize the on/off control of the relay.

2. Contact group: The contact group is a key part of the high and low voltage relay control circuit, which is divided into normally open contact and normally closed contact, which is used to control the disconnection and energizing of electrical equipment. The advanced degree of contact group technology directly affects the quality and reliability of high and low voltage relays.

3. Appliance base: The relay base is the support of high and low voltage relays, usually made of conductive materials. There are contact brackets on the base to secure the contact set. The relay base can also be used for protective housing and output wiring, which facilitates the interface between the relay and other equipment.

4. Spring: The spring in the high and low voltage relay is mainly used for the automatic disconnection and combination of the contact group on the bracket. The projectile should have good elasticity, durability and mechanical life to ensure the long-term stable operation of high and low voltage relays.
