A contact spring relay is an electronic component that uses a contact spring to control current. It is made by combining electromagnet, contact spring, shell, etc., through the action of electromagnet, it is elastically deformed, so as to realize the opening and closing control of the circuit.
Contact spring relays are mainly used in automatic control and automation devices. They have the advantages of fast response, high sensitivity, and high reliability. They are widely used in various fields such as industry, metallurgy, transportation, petroleum, chemical industry, and military affairs.
The working principle of the spring relay is to control the elastic deformation of them through the current of the electromagnet, so as to realize the opening and closing control of the circuit. When the current passes through the electromagnet, the electromagnet generates a magnetic field, and the action of the magnetic field makes the iron core of the electromagnet attract, so that it is displaced, and the contact is closed or disconnected, thereby controlling the opening and closing state of the circuit. When the current passes through the electromagnet, the spring will automatically spring back to its original position, so that the circuit returns to its original state.
There are different types and specifications of contact springs relays, and you can choose the appropriate model according to your needs. Among them, the quality and performance of the contact spring have an important impact on the working stability and life of the relay.
