Reed is a dry reed pipe for short, is a kind of passive electronic switching element contacts, with a simple structure, small size easy to control, etc., which is generally a sealed enclosure glass tube are installed there are two elastic spring plate of iron, also called rhodium metal filling with inert gas. Normally, the two reed glass tube made of special materials are separated. When a magnetic substance near the glass tube under the action of the magnetic field lines of the two reed tube is magnetized to attract each other. Features: (1) reed contacts are hermetically sealed within a glass tube with inert gas and do not receive any influence from the external atmospheric environment. (2) quick response (3) the structure comprises the operating parts and electrical circuits arranged coaxially. Reed switches are suited to applications in radio frequency operation. (4) reed switches are compact and light weight. (5) superior corrosion resistance and wear resistance of the contacts assures stable switching operation and long life. (6) with a permanent magnet installed, reed switches economically and easily become proximity switches.
