Switches (Solid State)

Products in this family use solid-state technology for detecting the presence of a magnetic field in excess of some specific magnitude and/or sign, and provide a two-state output indicating the presence or absence of such a field. They are distinct from reed switches, which provide a similar function through the use of moving mechanical parts, as well as from linear or compass-type solid-state devices which provide a variable output indicative of the strength and/or orientation of an applied magnetic field.
