A breakaway switch is a critical safety device used on towed trailers, particularly those with electric brakes. In the event that a trailer becomes detached from the tow vehicle, the breakaway switch automatically activates the trailer’s brakes, preventing a potentially dangerous runaway situation. Understanding the breakaway switch wiring diagram is essential for proper installation, troubleshooting, and ensuring the reliable operation of this vital safety component. Without a properly wired breakaway switch, the entire safety system is compromised.
