Sensing Conveyance System Limits, with Limit Switches.

The mass production of food products is a fascinating business, requiring the specification of many different types of technology in many different operating environments. In some cases, massive amounts of raw food product has to be carefully cooked and packaged… Continue reading Sensing Conveyance System Limits, with Limit Switches.

Defining Harsh Environments for Commercial Vehicles.

Sometimes clients come to us because they have a small need for switches on an outdoor application and want to design in a sealed switch that they won’t ever have to worry about.  A switch that is truly waterproof, with… Continue reading Defining Harsh Environments for Commercial Vehicles.

CPI Switches are a Big Turn-On

Perhaps it would be fair to say that only us engineering types might find this statement true at face value. After all, CPI switches once you really understand the design and engineering that has gone into them, conjure a certain… Continue reading CPI Switches are a Big Turn-On

Aircraft Fire Detection – Spot Fire detection Systems

For Aircraft and aviation related components, reliable high temperature detection is a key system for preventing a wide variety of in-flight system failures, or activating fail-safe mechanisms especially in so-called “spot-fire detection” applications. Indeed CPI’s X1 thermal switch is often… Continue reading Aircraft Fire Detection – Spot Fire detection Systems

Hardened Ball & Plunger Switches Get the Job Done

Ball & Plunger switches in our J4 series continue to achieve new design-ins in applications where their small size and extreme durability can’t be matched. Under our stainless steel hood resides 75 years of experience making hardened, reliable switching components… Continue reading Hardened Ball & Plunger Switches Get the Job Done

CPI 12 Volt Switches – An Enduring Legacy

For commercial applications of all kinds, switching 12 Volts is probably the most common bus voltage used with our sealed, waterproof limit switches. While CPI’s line of waterproof switches is rated to operate from 5V to 28V, 12 Volt applications… Continue reading CPI 12 Volt Switches – An Enduring Legacy

Electromechanical Limit Switches in Mobile Equipment

Back in the 1990’s, construction equipment manufacturers were filled with talk about completely eliminating switches with contacts by the year 2000.  Concerns over environmental sealing, failures due to contact contamination or degradation over time due to arcing in high-endurance applications drove this… Continue reading Electromechanical Limit Switches in Mobile Equipment

CPI Waterproof Switch Panels

Sometimes you need a switch that’s really, truly waterproof. Not just water-resistant or “splash-proof. And if you want one with carefully manufactured durability and extended temperature operation, well you’ve narrowed down the field even further. For tough marine or outdoor… Continue reading CPI Waterproof Switch Panels

Pushing the Limit on Limit Switch Applications

As one of the world’s premiere suppliers of electromechanical, high endurance waterproof limit switches for over 70 years, CPI has accumulated quite the resume of interesting switch applications.  Our original customers were military and high endurance outdoor vehicles like dump… Continue reading Pushing the Limit on Limit Switch Applications
