Application of Reed Switch and Magnetic Sensor

In addition to being used in reed relays and sensors, reed switches (reed switches) are widely used in circuit control, especially in the field of communication. The mechanical system commonly used in reed switch magnet drive, proximity sensor. Examples are door and window sensors in anti-theft alarm systems and anti-tampering methods.

The laptop uses a reed switch to put the laptop in sleep/hibernation mode when the lid is closed. The speed sensors of bicycle wheels and automobile gears use magnetic reed switches, which simply drive the magnets on each wheel through the sensors. Previously used for magnetic reed switches in computer terminals, where each key has a magnet, a keyboard that is actuated by pressing the key; a cheaper switch is being used. For pipe organs used by electric and electronic pedal keyboards, electronic organ players often use reed switches to touch the glass casing to protect it from dirt, dust, and other particles. They may also be used to control diving equipment such as flashlights or cameras, which must be sealed to keep pressurized water.

The reed switch can also be used in computer cooling fans and disk drives. As cheap Hall-effect sensors are available, they replace the ** switch and give a longer service life.
