How reed switches work (magnetically operated switches)
WebNov 27, 2021 · How does a reed switch work? 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 …
