Reed switches are highly reliable and cost-effective electronic components used in a wide range of applications. These switches are made up of two metal reeds that are hermetically sealed in a glass tube containing inert gas. When a magnetic field is applied, the reeds attract each other, completing an electrical circuit. Reed switches are commonly used in sensors, relays, and security systems, among other applications. They are known for their durability and long lifespan, making them an excellent choice for industrial and commercial applications.

Frequently Asked Questions (FAQs)
1. What is reed switch used for?
A reed switch is an electromagnetic switch used to control the flow of electricity in a circuit. They are made from two or more ferrous reeds encased within a small glass tube-like envelope, which become magnetised and move together or separate when a magnetic field is moved towards the switch.
2. What is an example of a reed switch?
Reed switches actuated by magnets are commonly used in mechanical systems as proximity sensors. Examples are door and window sensors in burglar alarm systems and tamperproofing methods. Reed switches have been used in laptops to put the laptop into sleep/hibernation mode when the lid is closed.
3. How reliable are reed switches?
Reed relays are considered to be the most reliable mechanical relay solution for low power switching. They have few moving parts and an inherently long mechanical life. However, not all reed relays are constructed to the same high standards.
4. Why do reed switches fail?
Reed switches or relays eventually fail in one of three ways . They do not open when they should (usually called “sticking”), they fail to close when they should (“missing”), or their static contact resistance gradually drifts up to an unacceptable level .
