With the popularization of smart homes, relays play an important role in scenarios such as smart lighting, smart security, and smart home appliances. For example, smart relays can remotely control home lighting, curtains, and other devices through a mobile app, enhancing users' convenience in life.

In medical equipment, relays are used to control the power supply, signal transmission, and other aspects of the device. For example, in high-end medical equipment such as CT machines and MRI machines, relays ensure stable operation and precise control of the equipment.

With the rapid development of new energy sources such as solar and wind power, relays have also been widely used in new energy generation systems. They are used to control the circuits of photovoltaic inverters and wind turbines, ensuring efficient conversion and transmission of electrical energy.
