Showing Results For: Reed Switches
Reed switches, or magnetic reed switches, are versatile electromechanical electronic components designed to operate or actuate by applying a relatively low magnetic field. These switches comprise two or more ferromagnetic, nickel-iron alloy or other metallic, thin, and flexible reed contacts/blades enclosed in an inert-gas-filled sealed glass tube. These magnetically permeable contacts are hermetically sealed, kept apart by a small air gap, and activated by the presence/absence of a magnetic field. These specialised reed switches feature resistance against moisture, dust, and other environmental contaminants. Additionally, reed switches come in normally open or normally closed configurations and can be customised to custom sensitivity levels.
Reed switches are simple yet versatile electronic components that offer several benefits in various applications. Here are some of the key advantages of using reed switches:
Upon applying a magnetic field near the reed switch, the integrated ferromagnetic material in the reed contacts becomes magnetised and attracts each other. This causes the switch’s closed state, a phenomenon when contacts come into contact and complete an electrical circuit. When the magnetic field is removed or reversed, the contacts spring back to their original position–breaking the circuit and returning to the open state.
Reed switches mainly come in two types based on their construction and operation:
Reed switches find applications in a wide range of industries, such as:
