Magnetic Reed Switch Market research report 2019-2024 presents a comprehensive study of the Magnetic Reed Switch Market in Global Industry. Magnetic Reed Switch consists of a pair of ferromagnetic reeds, which overlap at their free ends (contact area) at a very small distance and are hermetically sealed in a glass tube. When in the presence of a magnetic field, the reeds become magnetized to opposite polarity, thus attracting each other and closing contact. Like many other great inventions, reed switches were born at Bell Laboratories, invented there in the mid-1930s by Walter B. Elwood. Today, reed switches are still in common uses. The main market players are OKI, Littelfuse, RMCIP, Standex-Meder, Nippon Aleph, HIS Sensing, Coto, PIT-RADWAR, PIC, STG, Harbin Electric Group, Zhejiang Xurui Company and etc.
