When CPI started making thermal switches for the Military in the 40’s, there really wasn’t any other choice. Thermocouple based switches with variable set-points and various temperature ranges of operation were made using the thermocouple materials of the day, mostly… Continue reading When to use a Real Thermal Switch not a Sensor
Almost every large commercial machine with an engine or motor of some sort has a system for monitoring temperature. Critical systems that are thermally controlled can be designed to shut down or throttle operation to prevent system failure or deliver… Continue reading Monitoring Equipment Temperature is a SnapStat with CPI Switches
The design of the modern work truck is moving forward at an amazing pace. With long haul trucks, the focus has been on collision avoidance systems and advanced controls for fuel economy, but dump truck builders have long had a… Continue reading Dump Truck Safety System Design
In June of this year, CPI was approached to help sponsor an entry in the 14th International Submarine Race held June 22-26 at the U. S. Naval Surface Warfare Center’s Carderock test tank facility in Bethesda, MD. The contest is… Continue reading CPI Sponsors International Submarine Races
The world is full of companies that make a conscious choice to focus on quality and engineering excellence, as opposed to mass producing low cost high quantity commodity goods. Control Products is no exception. CPI decided as a fundamental business… Continue reading Thoughts on Quality – When Cheap is Just Another Kind of Expensive.
While there are hundreds of part numbers in our waterproof limit switch line, there’s only a couple basic ideas you need keep straight to understand how it all works. For the engineers among you, here’s an equation that might help.… Continue reading Panel Mount Pendants Keep The Neighborhood Clean
Systems like municipal water supplies, sewage treatment plants, massive cooling and lubrication systems used in chemical, petrochemical, and the oil and gas industry, all share one thing in common: large flow valves that are critically opened and closed by computer… Continue reading Valve Position Sensing for Mission Critical Flow Applications.
In the world of waterproof switches, designers understand pendant switches to be pushbutton switches that are hand actuated by an actual human. There are typically leads extending from the body of the switch which can allow an ergonomic distance between… Continue reading Sealed Pendant Switches – The Jewels of Waterproof Switches.
A quick web search for “Waterproof Rocker Switches” yields a universe of rocker switches, made for a universe of applications. Sadly even glorious Google can’t seem to completely sort out the waterproof variety from the more common standard PCB mounted… Continue reading Our Waterproof Rocker Switches… Rock!
Engineers and system designers looking for reliable switch products often face a quandary. Selection of switches with their inherent mechanical limitations must be pondered carefully or they risk being the proverbial “weakest link” in an otherwise robust control or safety… Continue reading Push Button Switch Types
