Reed Switch Magnet Interaction

Standex Electronics

This tutorial will define key terms for magnets and reed switches.  Additionally, it will describe how the positioning of the magnet’s north and south poles relative to the reed switch, produces different magnetic field arrays.  Understanding these magnetic field arrays will give insight into how the magnet and reed switch form their sensing function.
