One of the most popular limit switches CPI ever introduced has to be our J4 series waterproof limit switch. A small marvel of engineering originally developed for the military, this switch comes in both a ball switch and a plunger switch variation that use

The last thing Commercial vehicle and work truck manufacturers want to hear about is how someone got hurt while using one of their vehicles. In addition to the liability concerns, it’s just not good for sales when word gets out that safety systems on your

Lets face it folks, sometimes it just takes a plunger switch. Whether your application is mechanically or physically activated, the tactile feel, and extended actuator of a plunger switch may be the only real solution for your application. For engineers looking at a harsh duty, wet,

Liftgate manufacturers need to contend with a great many variables as they seek to make their hydraulic lift assemblies operational on the widest possible variety of vehicles. Is it a pickup truck, straight truck, van, or trailer application being used? What are body widths? Will it

CPI’s X1 thermal switch is being increasingly used by both American and European avionics manufacturers and integrators as their thermal switch of choice for spot detection of overtemperature conditions in systems throughout the aircraft. Recent integrations include FAA approval as a Fenwal replacement on Gulfstream

For many applications, standard garden variety ball switches won't cut it. In fact, even Google is confused about ball switches, conflating them with tilt switches that happen to use a floating ball in their implementation. But engineers know, that's not a real ball switch. So for the

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 monitoring
- Engine oil over temperature Read More...
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 copper, aluminum, and chrome. The

Sometimes in engineering design, you just get it right. The right combination of materials, simplicity and elegance. Just the right amount of cleverness. Sometimes it even looks pretty. Sure as time goes on you make tweaks here and there, but if your basic design is

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 cooling fluids that bring operation
