How Reed Switches are Produced

Reed Switches are magnetically operated devices and the core element in a Reed Switches, Reed Sensor, and Reed Relays.  Invented by Bell Labs in the early 1940's, Reed Switches work on simple principle of 2 overlaping feromagnetic iron blades that are hermetically sealled into a glass tube separated by a distance of only a few microns...
