CPI switches continue to see broad acceptance across the work truck industry, for applications where manufacturers are just tired of dealing with switch failures or unreliability in the field. Work trucks have a few operational characteristics that makes switch toughness and reliability a key consideration.
In short, this class of vehicles was born to use CPI’s hardened waterproof switches for many of their primary operator control switches, or safety limit switch applications. In 2018, here are just some of the work truck applications our switches have been designed into. Work Truck Application for CPI Waterproof Limit Switches Outrigger Locking Detection– On bucket trucks, fire engines, cranes, and other vehicles that use outriggers for stability, CPI Waterproof Limit switches detect when the outrigger is full extended and locked into position. PON/POFFApplications – On many types of work trucks, supplementary hydraulic controls require operator manipulation to turn on and off. CPI Pendant style switches are completely sealed and provide the electromechanical endurance operators need to turn on or manually control critical equipment. Liftgate Control– A common application for our switches is to control the up and down motion of a liftgate, especially since these systems are often mounted outside, on the liftgate itself. Dump Body Detect– Stories of dump trucks flying down the highway with the dump body up are sadly, all too real. Dump truck manufacturers need a reliable safety limit switch like our B9112 to raise alarms in the cab when the dump body is extended. Cranes– Whether they be truck mounted cranes or full construction cranes, cranes of all types and sizes have made use of our E1 waterproof limit switches in anti-two-block safety systems owing to their robustness and small form factor. They also use our J4 ball switch in hydraulic valve position detection applications using our specialized valve mounting brackets. Sanitation Trucks – Use our waterproof limit switches pre-mounted into a stainless steel control panel to control compressor and lift gate operations on the vehicle. Weatherproof Switch Panels– CPI has custom made switch panels and wiring for all kinds of vehicles who want a weatherproof, prewired option. Luckily all our waterproof switch come with panel mounting capability for use in any application. CPI Safety Limit Switches were Made for Work Trucks…On Work Trucks costing upwards of $100,000, its seems silly to take a chance on safety system sensors, with cheap, offshore produced switches. All CPI switches are designed and made in the USA right here in our East Hanover NJ Factory. Despite this, our switches often cost less in quantity than comparable switches by Honeywell, Eaton, and Otto. We love solving problems of safety and sensing with our switches.

Is it a pickup truck, straight truck, van, or trailer application being used? What are body widths? Will it be a swing up platform or a stowaway gate? What ground clearance and load must it support? Will it cantilever to support uneven ground? The list of considerations goes on well beyond these and fleet managers need to consider all them when designing liftgate solutions for their work trucks. One thing however that seems to be more agreed upon are the requirements of the platform activation switches. These are typically mounted in a fixed position on or near the liftgate. As such they are often exposed to the same conditions as the outside of the vehicle itself, namely rain, mud, dirt, wind, vibration and temperature extremes. Given the propensity for operators to ride up and down on the liftgate, they are often designed to go for the ride too. CPI Switches and Panels for Liftgate Control Because CPI’s switch construction is truly waterproof, not just splash-proof or water resistant, we can create assemblies out of our totally submersible basic switches and stainless steel panels that are perfect for a wet outdoor environment. Our assemblies are used in outdoor applications including lift gate up/down control, construction and mining equipment, as well as engine compartments in transit buses. Most commonly used for liftgate control and positioning is our E1333 seriesdual pushbutton switch panel to raise and lower the lift gates. The E1333 provides a short behind the panel depth requirement making it usable in places where other switches can’t fit. The CPI switch also provides low assembly labor to install with its integral PEM nuts and its packard connector. Lastly as opposed to electronic switches that require power from the circuit to operate the discreet CPI switch is resistant to failures due to poor grounds and its high electromechanical endurance. In fact our “snap action” contact design has been tested to over 500,000 “contactor” electrical cycles. Don’t worry about lead lengths either. Our switches and switch panels can be ordered from the factory at any custom lead length you need. The ability of our switch to withstand abuse at the hands of an operator or mother nature, really sets our products apart for most outdoor applications. And with convenient custom or stock panels, there’s one less piece of engineering you need to do. CPI Custom Waterproof Switch Panels Switch panelscome in a variety of configurations: separate circuits, in-series, and in-series with interlock (to prevent both switches from operating at the same time). We can produce multiple switch panels that also include additional electrical components such as LED indicator lamps per customer specification. CPI Waterproof Switch Panel Features / Options
