KSK-1E66 Series Reed Switch

The KSK-1E66 Series is a compact, high-reliability latching reed switch designed for automotive-grade, industrial, and general-purpose applications. Featuring a bistable (Form E) contact configuration, it offers magnetic latching functionality that enables power-efficient switching in battery-powered and low-energy systems.

With a glass body length of 14.0 mm and diameter of 2.2 mm, the KSK-1E66 supports rated power up to 10 W, switching voltage up to 200 VDC, and switching current up to 0.5 A. Its miniature form factor and UL approval make it ideal for integration into space-constrained designs requiring robust and long-lasting magnetic actuation.
