How reed switches work (magnetically operated switches)
https://www.explainthatstuff.com/howreedswitcheswork.html
WEBNov 27, 2021 · Artwork: The key to understanding reed switches is to realize that they are part of a magnetic circuit, as well as an electrical one: the magnetic field from the bar magnet is carried through the reed switch. That's what makes it close—and that's what allows electricity to flow through it.

Reed switch - Wikipedia
https://en.wikipedia.org/wiki/Reed_switch
WEBA reed switch has very low resistance when closed, typically as low as 0.05 ohms, whereas the Hall effect sensors can be in the hundreds of ohms. A reed switch requires only two wires whereas most solid-state devices require three wires. A reed switch can be said to require zero power to operate it.
