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.
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.
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.
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.
Selling Brand: Jammy
Application Reference: Trailer, electric brake, and breakaway system references in this listing describe application fitment only where the switch style, mount, lead length, wiring, and cable configuration match.
What This Means: This listing is for a Jammy J-ELEC breakaway switch with pull cable, not a complete breakaway battery kit unless specifically stated.
Before Ordering: Verify switch style, plunger style, lead length, mounting style, cable routing, and trailer brake wiring before installation.
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.
