With a unique, patented ball carrier design, CPI's J4 Series ball switches are like no other. High-temperature and high-pressure J4 Series plunger switches were developed for military and heavy-duty industrial applications. The harsh environment, coupled with the critical nature of this application has made CPI the leading supplier of air shut-off switches.

While all feature the patented ball carrier seal, plunger mechanisms are available with various seal configurations (o-ring, wiper or exclusion seals). Various standard actuators are available, and travel parameters are per application requirements.
