3. Setup and Installation
Proper installation of the CURT 52011 Breakaway Switch is crucial for its effective operation. This switch is designed for use with CURT Soft-Trac 1 and Soft-Trac 2 breakaway kits (sold separately).
Installation Steps:
- Mounting the Switch: Securely mount the breakaway switch to the trailer frame using the high-temperature weldable tab. Ensure the switch is positioned where the pull pin can be easily connected to the tow vehicle.
- Wiring Connections:
- Connect one wire from the breakaway switch to the positive (+) terminal of the trailer's breakaway battery.
- Connect the other wire from the breakaway switch to the trailer's electric brake circuit, typically to the blue wire leading to the trailer brakes.
- Connecting the Cable: Attach the breakaway cable to a secure, non-removable part of the tow vehicle, ensuring it is independent of the hitch. The cable should be taut enough to pull the pin if the trailer separates, but loose enough to allow for turns without accidental activation.

Important Safety Note: The breakaway device is not intended to be used as a parking brake. Always ensure your trailer's parking brake is engaged when parked.
4. Operation
The CURT 52011 Breakaway Switch operates automatically in the event of a trailer detachment.
How it Works:
- When the trailer is connected to the tow vehicle, the nylon pull pin is inserted into the switch body, keeping the electrical circuit open.
- If the trailer accidentally separates from the tow vehicle, the breakaway cable pulls the nylon pin from the switch.
- Removing the pin closes the internal electrical circuit, sending power from the trailer's breakaway battery directly to the electric brakes.
- This action applies the trailer brakes, bringing the trailer to a controlled stop.

5. Maintenance
Regular inspection and basic maintenance will ensure the longevity and reliability of your breakaway switch.
- Visual Inspection: Periodically inspect the switch body, cable, and wiring for any signs of wear, damage, or corrosion.
- Cable Condition: Ensure the breakaway cable is free of kinks, fraying, or excessive rust. Replace if damaged.
- Pin Functionality: Verify that the nylon pull pin can be easily inserted and removed from the switch.
- Battery Check: Ensure the trailer's breakaway battery is fully charged and in good working condition, as it powers the brakes through this switch.
- Cleaning: Keep the switch and its connections clean from dirt, debris, and moisture. The nylon case provides protection, but external cleanliness is still beneficial.
6. Troubleshooting
The CURT 52011 Breakaway Switch is a simple, robust component. Most issues are related to installation or the trailer's electrical system rather than the switch itself.
- Brakes Not Activating:
- Check the trailer's breakaway battery charge.
- Inspect all wiring connections for corrosion or looseness.
- Ensure the pull pin is fully removed from the switch.
- Verify the trailer's electric brakes are functioning correctly independently of the breakaway system.
- Accidental Brake Activation:
- Ensure the breakaway cable is not too short or improperly routed, causing the pin to be pulled during turns or bumps.
- Check that the pull pin is fully inserted into the switch.
If issues persist after checking these points, consult a qualified trailer technician.
