What is a Reed Switch?
A reed switch is an electromechanical switching device. The overall structure is simple. Two ferromagnetic blades that are hermetically sealed in a glass envelope. In other words, these components can exist or be used in almost any environment. Furthermore, the glass envelope has a temperature coefficient that exactly matches the Nickel Iron (NiFe) reeds.
简单的磁体相互作用打开并关闭簧片触点。更确切地说,由永磁体或电磁线圈产生的磁场的存在(或不存在)导致触点打开或关闭。开关触点打开时不会消耗电源。这种结构和操作的简单性允许簧片交换机没有易于佩戴部件,并且在众多行业中可靠地作为“开关”数十亿个操作。今天,所有主要的市场段都使用簧片开关技术。例如,测试和测量设备,医疗电子,电信,汽车,安全性和设备都使用基于簧片的开关组件。所以难怪,芦苇交换机增长率比以往任何时候都更强大,世界产出不能及时了解。
How Does a Reed Switch Work?
Reed switches work by reliably switching billions of operations using a simple magnet interaction to open and close contacts. First, the basic operation of a reed switch happens when it is brought into proximity of a permanent magnet, and the individual reeds become magnetized with the attractive polarity of the magnet. Second, when the external magnetic field becomes strong enough, the magnetic force of attraction closes the blades of the reed switch. Third, the magnetic field produced by the reed blades dissipate when the magnetic field is withdrawn.
Most importantly, since any residual magnetism on the reed blades would affect the opening and closing behavior. Therefore, the reed blades are annealed and processed removing any magnetic retention.点击这里to see a reed switch in action.
History of Reed Switch Technology
Bell Labs first invented the reed switch in the late 1930s. Although they have been in use for decades, not much has changed in regards to the operating principles of reed switches. In the 1940s, sensors and relays widely used reed switch technology. Moreover, early electronic and test equipment used reed switch components to perform stepping and switching functions. In the late 1940s, Western Electric central office telephone switch stations began using reed relays. Reed switch technology greatly improved telecommunications both in the 1940’s and still today.
