Global Magnetic Reed Switch Market Is Valued at 270 Million US$ in 2018 Is Expected to Reach 680 Million US$ by the End of 2025: QY Research
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...
