The ESCO LBS48‑16 Trailer Breakaway Switch with 48" Cable is a critical trailer safety component designed to automatically activate the trailer’s electric brakes if the trailer becomes disconnected from the tow vehicle. When separation occurs, the pull-pin is removed from the switch by the attached lanyard, closing the circuit from the trailer battery to the braking system and bringing the trailer to a controlled stop.

Built for reliability and easy installation, this heavy-duty breakaway switch includes a 48-inch safety lanyard cable and weather-resistant housing for long service life in demanding towing environments.

Ideal for utility trailers, equipment trailers, dump trailers, cargo trailers, and RV trailers, the ESCO LBS48-16 helps ensure compliance with safety regulations requiring breakaway braking systems on trailers equipped with electric brakes.

🔧 Key Features

• Automatic Emergency Brake Activation – Engages trailer brakes if the trailer disconnects from the tow vehicle.

• 48" Steel Lanyard Cable – Secure connection to the tow vehicle for reliable activation.

• Universal Electric Brake Compatibility – Works with most 12V trailer brake systems.

• Weather-Resistant Housing – Built to withstand road debris, moisture, and harsh weather.

• Compact & Easy Installation – Mounts near the trailer hitch with simple two-wire connection.

• Made for Trailer Safety Systems – Designed specifically for emergency breakaway braking systems.
