Reed Switch 3 Pin Magnetic Switch – Normally Open Normally Closed Conversion 2.5×14mm NO NC

The Reed Switch 3 Pin Magnetic Switch (2.5×14mm) is a compact, dual-function magnetic sensor used for contactless switching in a variety of electronics and automation applications. It offers both Normally Open (NO) and Normally Closed (NC) operation using a convenient 3-pin configuration, making it suitable for versatile wiring logic and control systems.

Its slim glass housing (2.5mm × 14mm) encases metal contacts that open or close in the presence of a magnetic field. This allows for wear-free, long-lasting operation in sensing and control circuits. Ideal for use in security systems, home automation, robotics, and IoT, the switch is easily mountable on breadboards or PCBs via through-hole solderable pins.
