LMMF Quick Disconnect Switch Box
Built for demolition derby reliability. Built for fast swaps and faster fixes.
The LMMF Quick Disconnect Switch Box gives derby builders a clean, organized way to control their electrical system. Additionally, it makes it incredibly easy to remove or transfer between builds.
Instead of rewiring every time you build a new car, this system lets you wire your components once. After that, everything connects using quick disconnect leads. As a result, you can remove the entire switch box or swap it into another car in seconds.
Perfect for derby drivers who are constantly rebuilding, repairing, and adapting between events.
Key Features
1. Quick Disconnect System
All components plug into dedicated quick disconnect leads. Install it once, and easily unplug the system for repairs, quick swaps, or transferring to your next build.
2. Built-In Emergency Backup
If something happens during a derby, you’re not out of the show. Simply run additional leads directly to the battery and plug your component in — bypassing the switch box entirely. This gives you a fast emergency backup system when things get rough.
3. Clearly Labeled Controls
Every switch is labeled for quick identification during the chaos of a derby:
• Ignition
• Fuel
• Aux 1
• Aux 2
• Starter Push Button
4. Integrated Voltage Gauge
Monitor your electrical system at a glance. You can also keep tabs on battery health while you’re in the heat.
5. Durable Die-Cast Aluminum Box
Mounted inside a rugged die-cast aluminum enclosure designed to handle vibration, impact, and derby abuse.
6. 5-Foot Quick Disconnect Leads
Extra length allows for clean wire routing and easy installation in a wide variety of derby builds.
Built for Derby Builders
This system was designed with the reality of derby cars in mind. That includes fast builds, quick repairs, and easy component swaps between cars.
Run it in your current car. Then unplug it after the show and drop it straight into the next build without rewiring everything.
Pro Tip: Pair this with a battery box for a clean, organized electrical setup.
