C&K’s ET series are sealed subminiature toggle switches, often used in the medical and telecommunications industry in hand-held or instrumentation applications. Featuring a small footprint (to help save space on the PCB) and ESD protection, long-lasting ET switches also come with strong protection from solder and cleaning process contaminants.

Features and Benefits

  • Sealed against solder and cleaning process contaminants
  • Compact size and small footprint save PCB space
  • ESD protection available

Typical Applications

  • Hand-held telecommunications
  • Instrumentation
  • Medical equipment
