20mm Silver Reed Switches are used to control the flow of electricity in a circuit. They are made having hermetically sealed glass envelope with pair of contacts on ferromagnetic reeds. Reed switches are generally used in applications or devices that have sensors like alarms, laptops, and refrigerators. 20mm Silver Reed Switches consume no voltage or electricity for their operation. Automatic cars too have reed switches because they have many safety sensors that rely on them.
We, Hangzhou Red Fir is main supplier of Reed switches in China.
We are developing and manufacturing a wide range of high-quality, high-reliability reed switches for India customers.
