WebApr 14, 2024 · Reed switches have a bounce/settling time that needs to be considered. Reed switches use no power in an open state. Reed switches are binary devices; they cannot tell between magnetic north and south poles. Hall effect sensors are digital devices; they do not experience a physical contact bounce. Hall effect sensors constantly drain a small ... WebHow Does a Reed Switch Work? Reed switches work by reliably switching billions of operations using a simple magnet interaction to open and close contacts. First, the basic operation of a reed switch happens when it is brought into proximity of a permanent magnet, and the individual reeds become magnetized with the attractive polarity of the magnet.

WebReed switches are normally operated with a magnet, but in a reed relay current flows through the coil to create a magnetic field and close the reed switch. Reed relays generally have higher coil resistances than standard relays (1000 for example) and a wide range of supply voltages (9-20V for example). WebAnswer (1 of 3): It has a contact in it which is moved by an external magnet. There are three types: Normally open, normally closed, and changeover.
