Description:
Reed switch is a kind of passive electronic switching component with contacts with a simple structure, small size and easy to control. Magnetic switch consists of a sealed glass envelope where there are two ferrous elastic reeds and is filled with inert gas called rhodium. Normally, the two reeds are separated in the envelope. When a magnetic substance approaches to the glass envelope, the reeds will come together due to the magnetic field thus completing an electric circuit. When the external magnetic field disappears, two reeds will be separated because of their elasticity, the circuit is also disconnected. Therefore, as a circuit switching device controlled by magnetic field signals, reed switch can also be used as a sensor for counting and limiting, etc. ( applied in the security systems, mainly used for production of door and window magnets), and it is also widely used in a variety of communications devices. In practice, it is common to use the two permanent magnets to control connection of two metal sheets, thus it is also called a "magnetic switch.".
