QuickCar Racing Products Battery Master Disconnect Switch — Red 2-1/2" Handle, Panel-Mount 12V

The QuickCar Racing Products 55-010 is a red, rotary battery master disconnect switch with a 2-1/2" square handle and black aluminum panel that gives you a reliable on/off master cut-off for 12V vehicle electrical systems.

This compact, panel-mounted master disconnect is built for motorsports and performance vehicles where a simple, visible battery shutoff is required for maintenance, storage, or race safety. It combines a chunky 2-1/2" square handle for easy operation with a rugged black aluminum mounting panel and a rotary switch mechanism designed to interrupt high-current 12V circuits quickly and cleanly.

How does the QuickCar 55-010 cut power to a vehicle?

The switch uses a rotary disconnect mechanism that physically separates the battery circuit when turned to the OFF position, preventing current flow. Turning it back to ON restores the connection without rewiring or removing battery cables.

• Rotary on/off action for immediate battery isolation
• Aluminum mounting panel for secure panel-mount installation
• Visible red 2-1/2" handle for quick identification and operation
• Designed for 12V vehicle electrical systems

What are the installation and fit details I should know?

The unit is panel-mount ready and fits common cutouts used in racing dashboards and service panels. It's supplied with a black aluminum on/off panel so you can mount the switch neatly and avoid extra fabrication for many vehicle-specific setups.

• Panel-mounted design: installs flush into a dashboard or service panel
• Includes black aluminum panel for clean, finished look
• Fit type: vehicle specific—check panel cutout and terminal clearance
• Rotary handle size (2-1/2" high x 2-1/2" wide) for positive grip

What electrical ratings and performance should I expect?

This master disconnect is built to handle high current loads common in performance and race cars while operating on a 12V system. As a dedicated battery master switch, it minimizes stray parasitic draw and provides a clear physical disconnect for safety and storage.

• Designed for 12V systems used in automotive and racing applications
• Robust rotary contacts for repeated make/break cycles under load
• Heavy-duty terminals to accept automotive battery cable sizes
• Aluminum panel resists corrosion and provides a mounting surface

How does this switch help in racing or storage situations?

In racing, a clearly visible master disconnect can meet event safety requirements and allow marshals or crew to cut power quickly. For storage or transport it prevents battery drain and reduces fire risk by isolating the battery from the vehicle wiring.

• Instant power cut for emergency or safety compliance
• Prevents parasitic drain during long storage periods
• Bright red handle for easy identification in a cockpit or trunk
• Durable materials suited to workshop and track environments
