Explanation of the working principle of 5v relay

Speaking of the 5v relay product, many people don't know it very well. In today's technological era, the use of relays is actually very extensive, and it will be used in many aspects, but people have not found it. Today, I will help everyone to learn more. Good understanding of 5v relay.

1. What is 5v relay?
Regarding the definition of 5v relay, a relay is actually an automatic control electronic device that when a certain input, such as electricity, magnetism, sound, light or heat, reaches a certain value, the output will change leaps and bounds. .
The relay has a control system (also known as an input circuit) and a controlled system (also known as an output circuit). Regulating and converting circuits, etc.

What is the working principle of 2.5v relay?
When the input of the 5v relay reaches a certain value, the "switch" in the relay will change, so that the controlled output circuit will be connected or disconnected. Different types of relays have slightly different principles. There are differences, but in general the same effect.

What is the use of 3.5v relay?
According to the industry used, relays can usually be divided into communication relays, automotive relays, home appliances relays, and machine tool relays.
