Web17 de set. de 2024 · Reed Switch: Reed switch was invented in 1936 Walter B. Ellwood in the bell telephone labs. Reed switch consist of pair of ferromagnetic flexible metal contacts nickel or iron which is easily magnetize and demagnetize. A reed switch a very low resistance when close typically 50mΩ. It requires zero power to operate. WebCurrent for a 12V at 5 Watt load is notionally given by. I = Power / Voltage. = 5W / 12V ~= 0.42A. so a 0.5A switch is notionally just within its rating. In practice it will probably have a short life. DC switch current ratings are usually related to the ability to not suffer arc damage when opened under load.
Web15 de mar. de 2024 · How Reed Switches Work in Different Environments. A magnetic reed switch can be used in a host of non-conventional, harsh conditions thanks to its inherent operational characteristics. For example, the device can maintain its magnetic sensitivity on exposure to shock and vibrations. WebOne of my school projects required magnetic sensing, and using a solid state hall switch beat out a mechanical reed switch in terms of price, size and reliability. I recklessly ordered high-sensitivity switches and used a really strong neodymium magnet which did work (perhaps a little too well, turns out the pull up resistors were magnetic too!) but obviously …
WebFirst, the magnet interaction effects the reed switch when a permanent magnet (as shown below) is brought into the proximity of the switch. What happens is the individual reeds become magnetized with the attractive magnetic polarity as shown. Second, the external magnetic field’s strength or magnetic force of attraction causes the reed ...
WebFurthermore, reed relays can work in far more advanced ways. For example, an RF reed relay application is designed to switch high frequency signals. Placing a coaxial shield around the reed switch or switches allows the relay to switch signals up to 7 GHz.
