Reed Switches
Reed Switches
have been around for a long time now and are still a popular choice for many switching
applications. Reed switches are electric switches that are operated by a
magnetic field, in their most basic form they consist of a pair of
ferromagnetic metal reed contacts hermetically sealed in a glass envelope with
terminals at each end. When the reed switch is in close proximity of a magnetic
field these metal reeds close forming a circuit. Likewise, when the magnetic
field is removed the circuit is broken. As a rule of thumb, the smaller the
reed switch then generally the more sensitive they are. Reed Switches are hermetically
sealed and they can operate in many environments, such as where flammable gases are
present and they also require zero power to operate if the applied magnetic
force is via a common magnet.
Reed Switches are utilised in many applications such as being utilised as proximity sensors monitoring the position of safety guards or doors and windows linked to an alarm system. You can find reed switches fitted to rotary devices as a form of speed sensor, opening and closing as a magnetic field passes by, used for level detection in tanks of liquid and even within a laptop causing the computer to go into sleep mode when the lid is closed.
