Panel Mount Pendants Keep The Neighborhood Clean

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.

(Sealed Pendant Switch) + (Mounting Bracket) = Your Ideal Waterproof Switch!

Waterproof Pendant Switches

Of course then there are a boatload of electrical, temperature, endurance, and ergonomic options you can specify for your basic pendant switch.  Likewise there are numerous stainless steel mounting brackets our switches will fit into including lever mount, roller, pipe mount, simulated lever, and of course hundreds of customizable options etc.

Some of our clients don’t even opt for a mounting bracket at all, preferring to hand actuate their switch or simply tie wrap it to their cab roll bar, bicycle handle, fishing rod, or whatever other unique application they have.

One other option that isn’t spoken about so often is our waterproof panel mount switch option. In this case we not only provide you a panel mount option for your chosen waterproof pendant switch, we provide you the panel too.

Waterproof Panel Mount Switches in Action

Enter Loadmaster of Norway Missouri, manufacturers par excellence of refuse collection vehicles (ie. garbage trucks). Loadmaster recently selected such a configuration for their latest fleet of high compaction rear-loaders as shown below:

In this application two custom CPI panel mounts were developed that are easily bolted to either the loadmaster-cpi-panel-mount-waterproof-switchesside of the vehicle. Meant to be operated by men with gloved hands, the switches selected allow operators in the rear to signal the driver in the cab when ready to move, or allow the operators to manually advance the compression throttle as a safety feature prior to moving the vehicle.

Selected for this was our K1163-501 and K1164-501 Single and Dual Panels respectively, using variations of our high actuation high force pendant switch. High actuation is better for gloved operation and high actuation force insures that the switches wont easily be activated by accident.

Panel Mounted Waterproof Pendant Switches for Your Equipment

If you have a rough duty piece of equipment begging for a reliable waterproof switch, its highly likely we have an off the shelf product that far exceeds the reliability and capability of what you have now. And we can even stick it in a stainless steel waterproof panel for you.

Why not make the switch to CPI today?

Valve Position Sensing for Mission Critical Flow Applications.

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 controls to insure proper system operation, or prevent critical safety thresholds from being violated. Flow rates in these systems can be 10’s of thousands of gallons per hour at high pressure so valve control has to work every time and failure is not an option.

It turns out that valve position sensing is one of the ideal applications for our line of CPI waterproof switches. To insure that valve positions are indeed fully closed or fully open, variations of our sealed momentary or toggle switches are mounted in a customized bracket that is affixed to the valve housing. Commonly used for example, are the E1 Momentary Contact Limit Switches. These switches are completely sealed in a watertight neoprene or santoprene enclosure depending on your temperature requirements with leads of any specified length extended from the housing.
Valve Position Sensing
This basic sealedwaterproof switch designis then used in any of dozens of mounting and actuator bracket combinations. Most common to the valve class of sensing is the simulated roller mount. As the valve arm slides over the roller in one direction it actuates the switch, sending confirmation to the control system that the valve is open/closed, and releasing when the valve moves the other way.

In the dirty, wet, extreme temperature environment that our switch commonly finds itself it, our sealed pendant mechanism is designed to survive, for thousands or even millions of cycles.

Cold Weather Switch Performance

While our switches can operate at high temperatures up to 120F, one of the more unique abilities of our designs is actually thier ability to operate at low temperatures, without sticking or freeze up. CPI engineers learned long ago the tricks related to insuring low temperature operation and making this engineering part of our manufacturing process. CPI switches can be specified for low temperature operations to -40F.
