Jammy Breakaway Switch with 48 Inch Coated Steel Pull Cable and 45 Inch Leads
Jammy J-ELEC breakaway switch for trailer emergency brake systems. Built with a 48 inch coated steel pull cable, zinc steel mounting plate, single-screw mount, and 45 inch wiring leads.
Overview
The Jammy J-ELEC is a trailer breakaway switch with a 48 inch coated steel pull cable and zinc steel mounting plate. It is designed for breakaway brake systems where the switch plunger is pulled during trailer separation, triggering the trailer brakes through the breakaway battery circuit. Use this replacement switch where the mount style, lead length, wiring layout, and pull-cable configuration match your trailer setup.
R&P Service Insight
A breakaway switch is a small part with a major safety role. When the trailer separates from the tow vehicle, the pull cable removes the plunger from the switch so the breakaway system can apply trailer brakes.
- Safety Trigger: The switch activates the trailer brake circuit when the plunger is removed.
- Independent Attachment: Attach the pull cable to the tow vehicle independently so it can pull cleanly during a separation event.
- Fit Check: Confirm the single-screw mount, 45 inch leads, and cable routing work with your trailer before installation.
R&P Knowledge Hub
Compatibility: Fits trailer breakaway applications where a J-ELEC style switch, single-screw mounting plate, 48 inch pull cable, and 45 inch leads match the existing setup.
Vehicle / System Fit: Intended for trailer breakaway brake systems using a battery-powered emergency brake circuit.
Installation Notes: One wire connects to breakaway positive power and the other wire connects to the trailer brake system. Verify your wiring layout before installation.
Performance Insight: When the plunger is removed from the switch, the trailer brakes are activated through the breakaway system.

R&P Repair Insight
Breakaway switch problems are often caused by damaged cables, missing plungers, corroded wiring, poor mounting, or incorrect routing. Replacing the switch is straightforward, but the emergency function depends on clean wiring and a cable path that can pull the plunger without snagging.
- Cable Condition: Replace damaged, frayed, kinked, or missing pull cables before towing.
- Mounting Check: Confirm the single-screw mounting plate can be secured in a location that allows a straight cable pull.
- Brake Function Test: After installation or testing, make sure the plunger is fully reinserted and the brakes are not left engaged.
