Now only home appliances are becoming more and more popular. Many electrical appliances will install relays to control electrical equipment. In the most popular words, it is a switch, which can automatically turn on or off the operation of electrical appliances after meeting certain conditions. Therefore, in many electrical appliances It will be installed in the control system, so how to wire the four-pin relay?

We can use ABCD to represent the four corners. First of all, we need to understand which two feet are the control feet. If A and B are control pins, connect pin A to the positive line on the switch, pin B to the negative line, pin C to the positive line, and pin D directly to the control element to complete the connection.
What to pay attention to when using relays
1. Be sure to use it within the parameters specified in the manual.
2. The rated load and life are only a reference range, and the specifics are also determined according to the environment and type of use, so it is best to determine in actual use.
3. It is best not to let the relay suffer a strong impact, such as falling to the ground, which will affect the use effect.
