Reed switch, also known as reed switch, magnetic switch, etc., can be divided into imported reed switch and domestic reed switch due to different production regions, normally open reed switch and normally closed reed switch due to different forms, and high-voltage reed switch and low-voltage reed switch due to different withstand voltages. However, no matter how it is distinguished, its characteristics and characteristics cannot be changed. It is a passive electronic switching element with contacts, which has the advantages of simple structure, small size and easy control. Its shell is generally a sealed glass tube, in which two iron elastic reed plates are installed, and an inert gas called rhodium is filled. Today, we will explain where reed switch is used and what role it plays.
1. Features: The dry reed tube is compact in structure and light in weight, and can be installed in extremely limited space, which is extremely suitable for miniaturized equipment.
2. Application: reed switch has been well used in mobile phones, program-controlled switches, copiers, washing machines, refrigerators, cameras, disinfection cupboards, door magnets, window magnets, electromagnetic relays, electronic weighing instruments, liquid level meters, gas meters, water meters, etc. Its main functions are alarm, warning and connection. For example, mobile phones, I believe many friends have used flip phones, and some flip phones will have LED lights flashing when the lid is closed, and the display screen will light up, among which is reed switch.
As for domestic reed switch, I wont mention it here because there is no agent, but most of them are used for toys and so on.
