KSK-1E85 Series Reed Switch
The KSK-1E85 Series is a high-power, high-voltage latching reed switch designed for robust performance in industrial, automotive, and test & measurement applications. Featuring a bistable (Form E) contact configuration, it enables magnetic latching functionality that maintains contact state without continuous power—ideal for energy-efficient designs.
With a glass body length of 21.0 mm and diameter of 2.75 mm, the KSK-1E85 supports rated power up to 100 W, switching voltage up to 350 VDC, and switching current up to 1.0 A. Its hermetically sealed construction and UL approval ensure long-term reliability in demanding environments.
