10 Pcs Normally Open Magnetic Induction Switch Vibration-resistance Electronic NO Switch 2*14mm DIY Magnetic Reed Switchs Electronic Component  for Arduino
Feature:
1. High Reliability:  N/O reed switch are non-contact magnetic switches, meaning they have no mechanical moving parts, resulting in a longer lifespan and high reliability. They are unaffected by friction, wear, or corrosion, ensuring stable performance over extended periods of use.
2. Sensitivity: Normally open reed switches are highly sensitive to changes in external magnetic fields. They can quickly detect magnetic field variations and switch when the magnetic field reaches a predetermined threshold. This allows for high-precision magnetic detection and control in many applications.
3. Environmental Resilience: Normally open magnetic induction switch  have excellent resistance to environmental interference. They can operate normally under various temperature, humidity, and pressure conditions, while also withstanding vibrations, shocks, and electromagnetic interference.
4. Space-saving: Normally open magnetic switch typically have a compact and small design, occupying minimal space. This makes them easy to integrate into applications with limited space, such as circuit boards, sensors, and electronic devices.
5. Low Power Consumption: Reed electronic NO switch consume very low power when not actively switching due to their operation being triggered by magnetic field changes. This reduces overall system power consumption, making them particularly suitable for battery-powered devices that require long-term operation.

Reed switch is the abbreviation of dry reed switch. It is a passive electronic switching component with contacts. It has the advantages of simple structure, small size and easy control. Its outer shell is generally a sealed glass tube, and the tube contains There are two iron elastic reed electric plates filled with an inert gas called metal rhodium. Usually, the two reeds made of special materials in the glass tube are separated. When a magnetic substance is close to the glass tube, under the action of the magnetic field lines, the two reeds in the tube are magnetized and attracted to each other. The reeds will attract together, connecting the circuits connected to the nodes. After the external magnetic force disappears, the two reeds separate due to their own elasticity, and the circuit is disconnected. Therefore, as a line switching device controlled by magnetic field signals, the reed switch can be used as a sensor for counting, limiting, etc. (mainly used in the production of door magnets and window magnets in security systems), and at the same time It is widely used in various communication equipment. In practical applications, magnets are usually used to control whether the two metal pieces are connected or not, so they are also called “magnetrons”.

Precautions for using reed switches:
1. Extreme care must be taken when cutting or bending the lead pins of the reed switch to avoid applying undue stress and damaging the glass-to-metal seal. Proper clamping tools must be used
2. Temperature and excessive exposure time may cause damage to the glass-metal seal (cracking, leakage, etc.), so fast and reliable welding technology (process) must be used. The recommended welding conditions are: 280 to 300°C for hand soldering and 250 to 300°C for wave soldering.
