When a magnet or coil creates a magnetic field that acts on the switch, both reeds of the reed switch become magnetized. An N pole is formed on the contact point of one of the reeds, and an S pole is formed on the contact point of the other reed. If the attractive force of the generated magnetic field causes the contacts to conduct, the circuit is closed. Once the magnetic field weakens to a certain extent, the reeds will separate again due to elastic force, which means the circuit is disconnected.

The advantages of compact structure, light weight, fast response time, long life and low cost. They are widely used in household appliances, industrial products, medical equipment, toys, fitness equipment, security, intelligent control, reed relays and other devices.
Reed switches have contact types of normally open (Form A), normally closed (Form B) and normally closed normally open conversion (Form C). They are triggered by the magnetic field generated by a permanent magnet or a current-carrying coil.
Reed switch consists of an elastic reed of magnetic material that is sealed in a glass tube filled with inert gas. The end faces of the magnetic sheets overlap but there is a certain gap in the middle, and the end face contacts are plated with a layer of precious metals (such as rhodium, ruthenium, etc.). Increases the stability of the switch and extends the service life of the machine.

A reed relay is a relay that uses a coil to generate a magnetic field to actuate a reed tube. It is a coil sensing device. Therefore, the characteristics of reed relays are small size, light weight, fast response speed, short bounce time and other characteristics. Mainly used in measurement equipment, communication equipment, security equipment, medical equipment, etc.
The main function of the relay is amplification. With a very small current, a circuit with a large power can be controlled, and the control range can also be expanded. When the signal reaches a certain value, the contacts can be switched simultaneously according to different forms of the contact group. Open and connect multiple circuits to achieve the purpose of automatic switching.
Proximity switch/proximity sensors are widely used in various household appliances, security systems, access control systems, safety interlocks, position positioning, and equipment automation.
Hall type proximity switch is composed of a reed switch and a permanent magnet. They are individually enclosed in a plastic housing for protection and ease of installation.
Proximity switches/proximity sensors are widely used in various household appliances, security systems, access control systems, safety interlocks, position positioning, and equipment automation.
Proximity switches/proximity sensors are therefore widely used in various household appliances, security systems, access control systems, safety interlocks, position positioning, and equipment automation.
Widely used in the control of water tanks, compressors and pumps, household appliances, medical equipment, industrial braking, petrochemicals, food processing, electric power, public works, vehicles and ships, etc.

When a water leak occurs in a facility or equipment and water contacts both electrodes of the sensor at the same time, it will trigger the relay in the sensor to work and control the external alarm or water pump, solenoid valve and other equipment connected to it.
When the pressure in the system is higher or lower than the rated safety pressure, the disc in the sensor moves instantaneously, and the switch joint is turned on or off through the connecting rod. When the pressure drops or rises to the rated recovery value, The disc instantly resets and the switch automatically resets, or simply put, when the measured pressure exceeds the rated value, the free end of the elastic element is displaced, pushing the switch element directly or after comparison, changing the on-off state of the switch element, to achieve The purpose of controlling the measured pressure.
When the pressure in the system is higher or lower than the rated safety pressure, the disc in the sensor moves instantaneously, and the switch connector is pushed on or off through the connecting guide rod. When the pressure drops to or rises to the rated recovery value, the disc resets instantly and the switch resets automatically. In simple terms, when the measured pressure exceeds the rated value, the free end of the elastic element is displaced, and the switch element is pushed directly or after comparison, changing the on-off state of the switch element to achieve the purpose of controlling the measured pressure.
Temperature sensor products have stable performance, reliability and long life;NTC uses a temperature chip with a curve β value of ±1% and a resistance R value accuracy of ±1%.
