Breakaway Switch Nylon w / Weldable Tab

The Breakaway Switch Nylon with Weldable Tab is an essential safety component for trailer electrical systems, designed to protect your tow vehicle's wiring and battery from damage during trailer detachment. This REESE-engineered device automatically interrupts the trailer circuit when a breakaway occurs—whether from accidental uncoupling or emergency disconnect—preventing backfeeding voltage and short circuits that could disable your towing vehicle's lights or damage sensitive electronics. As a mechanic who has spent years troubleshooting electrical gremlins on tow rigs, I can tell you this is one of those understated components that saves you from expensive headaches.

Constructed with durable nylon housing and rated for standard 12-volt trailer brake systems, the Breakaway Switch Nylon features a weldable tab that integrates seamlessly into your trailer frame or tongue structure—no drilling required if you're comfortable with a MIG welder. The internal mechanism uses a simple, reliable mechanical design that requires no batteries or external power; the switch activates purely through physical tension on the breakaway cable. At just 0.41 pounds and measuring 5.9 x 1.65 x 5.9 inches, installation is straightforward on single-axle or multi-axle trailers, and the compact form factor doesn't interfere with cargo or frame geometry during routine towing operations.

Whether you're hauling utility, enclosed, or boat trailers, the Breakaway Switch Nylon meets DOT safety standards for commercial and personal use and integrates with any 12-volt trailer brake system using a standard breakaway cable. Experienced tower operators and fabrication shops favor REESE products for their field-proven reliability under real-world conditions—freeze-thaw cycles, vibration, and salt exposure don't degrade performance. Install this switch as part of your brake system refresh, or retrofit it to older trailers that lack integrated breakaway protection; either way, you're adding a critical fail-safe that keeps both your rig and other road users safe.
