Valve position Sensing with CPI Switches
One of the more creative uses of CPI waterproof limit switches is their use as position sensors on a wide variety of both manually operated, and servomotor control valves. These valves may be used to regulate the flow of everything
Neutral Safety Detection was Made for Our Hardened Ball Switch
In the old days of manual stick shifts, attemps to start a vehicle when the car was not in neutral provided some serious kinetic feedback in the form of a lurch forward or backward. It is not hard to imagine
Electromechanical Switches in Work Vehicles are Here To Stay
As a maker of some of the worlds premier, high durability, electromechanical switches, we can now say for sure that there are some things no other switch technology can do.
CPI Switches Race for Glory
Vintage Indy car racing might not be a place you would expect to find CPI’s Waterproof Switches, but when you think about it, what better place for a switch that has to perform reliably 100% of the time? For those
Looking at 2021 – The Rear View Mirror that Wasn’t
Like many other USA based manufacturers, CPI had many reasons to be optimistic about 2021 back in December of 2020. A COVID vaccine was on the horizon, business was off, but continued at reasonable levels. There was lots of talk
Keeping Electronics Warm in Cold Temperatures
Most of us are aware of the dangers of overheated electronic components, manifesting itself in ways as simple as component failure all the way up to system failure, explosions, and fire. CPI thermal switch reliability has had a hand in
CPI Thermals Do Their Part to Thwart Bank Robbers
In the good-old days, your basic bank heist required little more than some nerves of steel, a simple disguise, and a handwritten note demanding cash. Indeed as recently as 1992 in cities like Los Angeles and New York, there were
Fuel Cell Thermal Management by CPI
As we all look forward to a greener, more sustainable energy future, the promise of hydrogen based fuel cells is certainly one of the most exciting energy technologies on the cusp of mainstream acceptance. Fuel cells were a 10 billion
CPI Helps Keep Windmills Warm
Earlier this year the state of Texas saw one of its most devastating statewide power outages when winter storms rolled through the state and left freezing temperatures behind for weeks. While the vast majority of power was lost due to
CPI Thermal Switches, Tried and True for Aviation Applications
Power requirements in your average helicopter represent a few uncommon challenges. Consider the startup power required to get those turbines spinning. Then the instantaneous braking force necessary to respond to the pilots commands in real-time as he dips and rises
