Magnetic reed switches are electronic devices that consist of a pair of ferromagnetic flexible metal reed contacts enclosed in a hermetically sealed body made of glass, magneshere, or other molded materials. These switches are designed to operate when a magnetic field is applied to them, causing the contacts to either close or open. When the magnetic field is present, the contacts of the switch are closed, and when it is removed, they return to their original position, which is usually open. The switch can be actuated by either an electromagnetic coil or a permanent magnet that is placed near the switch. Magnetic reed switches are typically used in electronic circuits that require a simple and reliable means of detecting and responding to the presence or absence of a magnetic field. These switches are commonly used in applications such as security systems, medical equipment, automotive sensors, and industrial controls. The contact forms of magnetic reed switches include single-pole-single-throw (SPST) and single-pole-double-throw (SPDT). The SPST switch has a single output that is either on or off, while the SPDT switch has two outputs that can be switched between two different states. In summary, magnetic reed switches are electronic devices that consist of a pair of flexible metal reed contacts enclosed in a sealed body. They are actuated by an applied magnetic field and are typically used in electronic circuits that require a reliable means of detecting and responding to the presence or absence of a magnetic field. The contact forms of these switches include SPST and SPDT, making them suitable for a wide range of applications in various industries.
