The 3-wire trailer breakaway switch is a critical safety component for any trailer equipped with electric brakes. Its primary function is to automatically activate the trailer’s brakes if the trailer becomes detached from the tow vehicle while in motion. Understanding the wiring diagram for this switch is essential for proper installation, maintenance, and troubleshooting, ensuring the system functions reliably when needed most. Correct wiring ensures that the breakaway system acts as a last line of defense against a runaway trailer.
