WebNov 8, 2024 · The reed switch consists of two ferromagnetic material sealed in glass or plastic. The two materials do not initially touch each other, but when a magnetic field from either a permanent magnet or an induced one (from a current-carrying coil) is placed near the reed switch, the switch closes and makes electrical continuity. 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.
