WebReed Switch Sensors are magnetically activated mechanical switches. The size of the switch determines both the sensitivity and the amount of power the sensor is capable of switching. Reed switch sensitivity is defined in Amp Turns (AT). The lower the AT value, the smaller the magnetic field will be that is required to switch the sensor.

WebJun 19, 2024 · Almost all electrical float switches work by using a magnet to open and close a reed switch. How Stem-mounted Float Switches Work Stem-mounted float switches use a magnet in a float that passes over the reed switch with the rising or falling action of the liquid, either opening or closing the switch. Reed switches come in two main varieties called normally open (normally switched off) and normally closed (normally switched on). The key to understanding how they work is to realize that they don't just work as an electrical bridge but as a magnetic one as well: magnetism flows through them as well as electricity. See more As you bring a magnet up to the reed switch, the entire switch effectively becomes a part of a "magnetic circuit" that includes the magnet (the dotted line in the artwork shows part of … See more You can also get reed switches that work the opposite way: the two contacts are normally snapped together and when you bring a magnet up to the switch, spring apart. Reed switches … See more Another crucial thing I need to point out is that reed switches don't simply switch on when a magnet moves up close and off when it moves away (in the case of a normally open/off … See more WebMar 15, 2024 · Reed Switches: This devices have magnetic contacts contained in a glass tube. These contacts can be affected by excessive mechanical shock. Hall Switches: These sensors are contained in a semiconductor device.
