This document describes the features and performance of the C&K E Series sealed miniature rocker and lever handle switches. These switches are sealed against solder and cleaning process contaminants, have ESD resistance, and are UL 94V-0 and RoUS compliant.
The C&K E Series offers sealed miniature rocker and lever handle switches for telecommunications, instrumentation, ESD‑resistant applications, and computer peripherals. Models are available in SPDT, DPDT, and 3‑pole configurations with a variety of actuator styles and frame colors.
The leaflet lists detailed electrical ratings, material constructions, and optional hardware such as panel mounts, quick‑connect terminations, and LED‑compatible inserts. Ordering information and part numbers are provided for each actuator and termination option.
