10a relay products are automatic switching elements with isolation function, which are widely used in remote control, telemetry, communication, automatic control, mechatronics and power electronic equipment, and are one of the important control elements.

10a Relay products generally have an induction mechanism (input part) that can reflect certain input variables (such as current, voltage, power, impedance, frequency, temperature, pressure, speed, light, etc.); it can achieve "pass" to the controlled circuit , "Off" control actuator (output part); between the input part and output part of the relay, there is also an intermediate mechanism (drive part) for coupling and isolating the input, functional processing and driving the output part.

10a relay products are used as control components. In summary, relays have the following functions:

1) Expand the scope of control. For example, when the control signal of the multi-contact 10a relay products reaches a certain value, the multiple circuits can be switched, disconnected, and connected at the same time according to different forms of contact groups.

2) Zoom in. For example, sensitive relays, intermediate relays, etc., with a very small control quantity, can control a circuit with a large power.

3) Integrated signal. For example, when a plurality of control signals are input to a multi-winding relay in a prescribed form, they will be compared and integrated to achieve a predetermined control effect.

4) Automatic, remote control and monitoring. For example, the 10a relay products on the automatic device can be combined with other electrical appliances to form a program control circuit to realize automatic operation.
