What Is a Reed Switch and How Does It Function in Electronic Circuits?
A reed switch is an electromagnetic switch that operates when a magnetic field is applied. It consists of two ferromagnetic contacts sealed within a glass tube. When a magnet approaches, the contacts close, allowing current to flow. When the magnet moves away, the contacts open, stopping the current.
According to the Institute of Electrical and Electronics Engineers (IEEE), reed switches provide reliable switching mechanisms in various electronic devices due to their compact size and durability. This is especially useful in applications such as security systems and sensing devices.
Reed switches are typically used in applications such as automotive equipment, home appliances, and industrial machinery. They are valued for their simplicity, speed, and contact reliability.
