Explore reed switches for electronic circuits, security systems, automation projects and position detection applications. A reed switch is a magnetically operated electrical switch that changes state when a magnetic field is brought close to the contacts.
Choose the appropriate magnetic reed switch according to contact type, switching voltage, switching current, physical dimensions and mounting method. Reed switches are commonly used in door and window sensors, level detection, position sensing and low-power control circuits.
How to Choose a Reed Switch
When selecting a reed switch, check the contact configuration, maximum switching voltage and current, sensitivity, dimensions and operating distance with the intended magnet. These parameters determine whether the switch is suitable for the circuit and mechanical installation.
Reed switches are widely used in magnetic sensors, security systems, automation equipment, position detectors and electronic projects. Because the contacts are activated magnetically, they can provide simple non-contact detection without requiring a mechanical actuator.
