High power reed switch series are used in high power switching applications up to 120 Watts. These switches are used in proximity, position, motion and end-limit sensing. Reed relays containing these switches include our KT, SHV, LI, and BE series. High power reed switch products are ideally suited in automotive, test and measurement (ATE), high power, and high voltage applications.
