Reed switch is the abbreviation of dry reed switch. It is a kind of contactless passive electronic switch element. It has the advantages of simple structure, small size and easy control. Its housing is generally a sealed glass tube. There are two iron elastic reeds and an inert gas called a metal crucible. At ordinary times, two reeds made of special material in the glass tube are separated. When there is a magnetic substance near the glass tube, the two reeds in the tube are magnetized and attracted to each other under the action of the magnetic force lines of the magnetic field, and the reeds are sucked together so that the circuit connected to the node is connected. After the external magnetic force disappeared, the two reeds were separated due to their own elasticity and the line was disconnected. Therefore, as a line switching device controlled by a magnetic field signal, the reed switch can be used as a sensor for counting, limiting, etc. (in the security system, it is mainly used for making door magnets and window magnets), and also It is widely used in various communication devices. In practice, the permanent magnets are usually used to control whether the two metal pieces are connected or not. Therefore, they are also called “magnetrons”.

Features and applications:
1, The dry reed pipe has a compact structure and a small weight, and can be installed in an extremely limited space, which is very suitable for a miniaturized device.
2. The switching elements of the dry reed switch are hermetically sealed in an inert gas atmosphere and will never come in contact with the external environment. The working life is long.
3. Dry reeds do not use sliding elements, so metal fatigue associated with all metal degradation will not occur, ensuring virtually unlimited mechanical life.
4, The reed switch is very popular in mobile phones, program-controlled switches, copiers, washing machines, refrigerators, cameras, disinfection cupboards, door magnets, window magnets, electromagnetic relays, electronic scales, level gauges, gas meters, water meters, etc. Good application.
