CPI Thermal Switches – Keeping Astronauts Safe on the ISS
The International Space Station (ISS) may be one of the most underappreciated technological (and geopolitical) marvels on, or off the planet. While it has been under development since the 1990’s it is actually the joint effort of five different space
CPI’s J4 Ball Switch – A Problem Solver for the Military and Beyond
Sometimes, the best engineering advances arise out of failure. To quote Thomas Edison “I have not failed. I’ve just found 10,000 ways that don’t work!” Indeed as one looks at the development history of CPI’s patented J4 ball switch, its
CPI Thermal Switches Are Heating Up
The vast majority of thermal switch applications we get have to do with keeping things from getting too hot. Just a few examples of this include: Gally fire detection Avionics Bay Over Temperature Brake over temperature warnings Hydraulic fluid temperature
Waterproof Toggle Switches for Marine and Outdoor Applications
For many applications requiring robust toggle switch functionality CPI sealed, waterproof toggle switches can be a good solution. Whether your application is hand actuated or needs be actuated mechanically, we have a complete off the shelf part configuration that incorporates
New MSHA Specification Requires Compressor Thermal Monitoring.
If you’re a manufacturer of high pressure, high horsepower industrial air compressors, like the kind that might be used in large drilling or mining operations, you need to know that the Mine Safety and Health Administration has new safety requirements
Safety Systems on Work Trucks
The broad category of “Work Trucks” or “vocational trucks” includes vehicles from ambulances to class 8 heavy trucks weighing over 33,000 pounds . Unlike cars and your consumer oriented pickup truck, these vehicles really work for a living, and are
First Responders Rely On CPI Switches
Emergency vehicles like ambulances, law enforcement vehicles, police cars and motorcycles, and fire trucks represent some very specially designed vehicles. Packed with special equipment, and special usability requirements, these vehicles are equipped with safety systems and fail safe systems way
When to use a Real Thermal Switch not a Sensor
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
Military Grade Waterproof Switches
At CPI, we’ve been telling people for years about the robustness and reliability built into every USA designed and manufactured waterproof switch that we make. For applications from recreational vehicles, to advanced military and avionics applications, CPI switch hardware gets
When Old Technology Becomes New Again – Part II
Two important considerations when looking at the integration of any hydraulic linear position sensor are the underlying technology and the packaging of the transducer. These principles effect size, life, maintainability, and above all, durability. The underlying technology used influences the
