Reed switches in Lightsabers

Light Sabers are weapons used by the Jedi and the Sith, in the fictional Star Wars Universe, set in a galaxy far, far, away! Toy versions of Light sabers are replicas that look and sound like the ones used in the movies and TV shows.

Reed Switches are used in these devices to power up the light saber only when the owner places a magnet in a specific location on the handle or wears a ring with magnet that actuates the reed switch under the handle, before turning it on. This is used to give others the impression that the “force” is only with the person handling the saber as it will not work when others try to turn it on. With the reed switch and magnet in place, the circuit closes and the power button turns the saber on. If the magnet is not in place, the circuit is incomplete and anyone else trying to the turn the saber on, cannot.
