Answer: 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.
Answer: 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.
Answer: Reed switches or relays eventually fail in one of three ways . They do not open when they should (usually called \u201csticking\u201d), they fail to close when they should (\u201cmissing\u201d), or their static contact resistance gradually drifts up to an unacceptable level .
