Normally Open Magnetic Reed Switches, 2 * 14mm Reed Switch
The Normally Open (NO) 2x14mm magnetic reed switch is a compact, highly reliable electromechanical component engineered for non-contact proximity sensing and magnetic field detection. Encapsulated in a hermetically sealed glass envelope filled with a protective inert gas, it consists of two flexible ferromagnetic reeds that remain open in their default state and mechanically snap closed when exposed to an external magnetic field. Measuring 2mm in diameter and 14mm in length, this miniature switch offers exceptional resistance to dust, moisture, and chemical corrosion, ensuring a long operational lifespan with millions of reliable switching cycles. It serves as an essential, cost-effective solution for a wide range of applications, including DIY electronics projects, smart home security setups for door and window sensors, liquid level indicators, rotational speed counters, and limit switches when paired with permanent magnets or microcontrollers.
