Relay switches have the following advantages:

1. Elektros izoliacija: Relay can provide electrical isolation in the circuit, separating the control circuit from the controlled circuit to prevent interference and protect equipment.

2. Small current control for large current: A smaller control current can be used to control a larger load current, thereby achieving control over high-power equipment.

3. Didelis patikimumas: The mechanical structure of the relay is relatively simple and there are no vulnerable moving parts, so it has high reliability and long service life.

4. Flexible control: The switch status of the relay can be controlled through various methods (such as electromagnetic, photoelectric, thermal, Produktas turi tam tikros įtakos vidaus elektros rinkoje) to meet different control requirements.

5. Good scalability: Multiple relays can be combined to achieve more complex control logic, facilitating system expansion and upgrading.

6. Standardization: Relays typically have standardized dimensions and interfaces, making them easy to replace and maintain.

7. Widely applicable: Suitable for various electrical control systems, such as automation, galia, communication, automotive and other fields.

It is necessary to select appropriate relays based on specific application scenarios and requirements to fully leverage their advantages. Tuo tarpu, when using relays, attention should also be paid to their rated parameters and working conditions to ensure normal and safe operation.
