Information

In our electricity facilities,we often use an electrical appliance that is a relay,which is used in automatic control circuits and is a switch for current operation.It has the functions of conversion circuit,automatic adjustment,and safety protection.Commonly used relays are relay 5v and 12v relay.There are different types of relays according to different working principles and structural characteristics.

12v relay


1. Electromagnetic relay,as the name suggests,is an electrical device that works on the principle of electromagnetic effect.It uses the magnetic effect to connect the power box to cut off the power supply.

2. A reed relay is a sensing device that induces current in a coil.It is a device that closes or opens the circuit when there is a magnet metal or other magnetically conductive objects approaching.It has a very strong structure and high durability, and is used as a limit switch for the position of mechanical equipment,and can also be used to detect windows and iron stores that are not in their designated positions.

3. The time relay is an electrical appliance controlled by time delay,and there are many types of it.Air damping time relays are commonly used in AC circuits,which can effectively delay the time of power-on and power-off according to their own working principles.

4. The mechanism used to query and control the temperature based on natural induction materials is called a thermal reed,and its working principle is to use the special material (temperature-sensitive magnetic) to be sensitive to the surrounding temperature.
5. Opto-mechanical electrical appliance is a device that controls the transmission of optical signals.

6. Intermediate relays are used in many automatic control and protection circuits, which are very convenient for installation and wiring, long use time, low power consumption,and light tube indication after work,which is convenient for on-site observation and renovation.
