Whether you are outfitting a new dump body or replacing a damaged switch on an existing rig, this 50-amp rotary switch kit delivers the robust performance required in harsh commercial environments. Unlike cheap toggle switches that easily break or short out, the rotary barrel design offers positive, tactile feedback and superior resistance to dust, dirt, and moisture.

What is Included in the Rotary Switch Kit?

The DeBrovys Rotary/Barrel Switch Kit comes with everything you need to mount and wire the control switch in your cab or externally on the truck body. We have taken the guesswork out of the installation process by bundling all the necessary hardware and safety components into one comprehensive package.

Inside the kit, you will find the heavy-duty 50-amp rotary switch itself, featuring a durable metal shaft and solid contact points. It also includes a sturdy metal mounting bracket with a pre-drilled faceplate clearly labeled for "Wind Tarp" and "Unwind Tarp" operation. To protect your tarp motor from electrical spikes, we include an auto-resetting circuit breaker. Finally, the kit provides an indicator light to show when power is active, along with all necessary wire terminals, ring connectors, and mounting fasteners.

Universal Compatibility with Major Tarp Systems

One of the biggest advantages of the 25-P-500B Rotary Switch Kit is its universal design. It is engineered to work seamlessly with 12-volt DC electric tarp motors across a wide range of brands. If you are running a standard front-to-rear flip tarp system, this switch will get the job done.

This kit serves as a direct replacement for switches used in systems by Donovan, Roll-Rite, Aero Industries, US Tarp, Buyers Products, Mountain Tarp, Pull Tarp, and Tarping Systems Inc. (TSI). No matter what brand of Truck Tarp Systems you currently have installed, this rotary switch will integrate perfectly and restore full functionality to your rig.

Technical Specifications

Built for the demands of the trucking and waste industries, this switch kit meets strict electrical and mechanical standards. Below are the core specifications for the rotary barrel switch kit:

Why Choose a Rotary Switch Over a Toggle Switch?

Many operators wonder why they should upgrade to a rotary barrel switch instead of sticking with a standard toggle switch. The answer comes down to durability and current handling. Electric tarp motors draw a significant amount of amperage, especially when pulling a heavy Waste Industry Tarp over a heaped load. Standard toggle switches often have internal contacts that are too small to handle this sustained current, leading to overheating, melting, or premature failure.

The rotary barrel switch uses heavy-duty internal copper contacts that are specifically designed to handle high-amperage reversing DC loads. The twisting motion of the rotary knob physically forces the contacts together with more pressure than a toggle spring can provide, ensuring a solid electrical connection every time. Furthermore, the enclosed barrel design does a much better job of keeping out the dust, mud, and moisture that are inevitable on construction sites and in landfills.

Installation and Wiring Guidance

Installing the DeBrovys rotary switch kit is a straightforward process for anyone familiar with basic 12-volt automotive wiring. The included metal bracket can be mounted inside the cab under the dash, or securely fastened outside the truck near the hydraulic controls. The faceplate is clearly marked, making operation intuitive for any driver.

When wiring the switch, it is critical to use the appropriate gauge wire—typically 6 AWG or 8 AWG—to handle the 50-amp current without voltage drop. The included auto-reset circuit breaker must be installed inline between the battery power source and the switch to protect the tarp motor from burning out if the tarp becomes jammed.
