Our relay is an electrically operated switch. It consists of a control circuit and a load circuit. In the control circuit, a relatively small electrical current is used. When this current is applied, it activates an electromagnet within the relay. The electromagnet then causes a mechanical movement which closes or opens the contacts in the load circuit. Relays are widely used in various electrical systems. In automotive electronics, they can be used to control high power devices such as headlights or the starter motor. In industrial control systems, relays are often used for isolation between different parts of a circuit, protecting sensitive components from high voltage or high current surges. They also play an important role in automation processes, allowing for the control of multiple devices based on different electrical signals.

Others
1.All the performance data listed in the data sheet are the initial values tested under standard testing condition.
2.Unsealed relays should be hand soldered to avoid flux contamination of the relay.
3.To avoid using relays under strong magnetic field because it will change the parameters of relay such as pull-in and drop-out voltage.
4.To maintain the performances of relays, please do not make the relay drop or be shocked strongly Suggest that the relays dropped not be used.
