Lightsabers are science fictional weapons used in the Star Wars stories, set in a galaxy far, far, away! Lightsaber toys are replicas that look and sound like the lightsabers used in these movies. Reed Switches are used in these devices to power up the lightsaber only when the owner places a magnet in a specific location on the handle or wears a ring with magnet and picks up the light saber for turning it on. This is used to give others the impression that the “force” is not with them and only with the person handling the saber! Any of our ultra-miniature reed switches UM-0018-M, UM-0018-H that can be PCB mounted or our reed sensors MS-104, MS-105, R3 or R5 can be used for such applications.
