A relay is a device that generates a magnetic field through an electromagnetic coil and drives metal springs or contacts to switch circuits. When the coil is powered on, it will attract the moving contact and the stationary contact, thereby achieving the control of circuit closure or disconnection. 

It has the following characteristics:

• High insulation: The control end is electrically isolated from the load end to ensure system safety.

• Strong carrying capacity: switchable between high voltage and high current, suitable for various loads.

• Reliable and durable: stable mechanical structure, long lifespan, and stable performance.

• High universality: suitable for AC/DC power supply, with a wide range of applications.

   

Application fields:

Relays are widely used in industrial automation, household appliances, power control systems, communication equipment, and automotive electronics, and are a classic and mature circuit switching solution.

You can choose the appropriate relay model based on the actual application field or according to the voltage, current, and other parameters required by the electrical equipment.
