High-Current Futaba FUEBA0323 On/Off Power Harness ESW-1J for RC Models  [FUEBA0323]

Built for heavy-current service

The Futaba FUEBA0323 ESW-1J high-power on/off electric switch harness is a purpose-built RC accessory that installs a sturdy manual power switch into the battery circuit. Heavy-gauge wiring is used to handle higher current routing between battery, receiver and electronic speed controller (ESC) across electric models.

With a focus on durability and ease of servicing, the harness lets you isolate battery power cleanly during transport, storage or pit-side checks without unplugging connectors. The neutral design makes it suitable for a wide range of electric models including cars, aircraft and boats where a strong manual cutoff is required.

Installation notes and practical tips:

• Secure the switch to a robust part of the chassis to minimise movement and vibration over time.
• Avoid routing the harness near heat sources and sharp edges; protect exposed sections with sleeving if needed.
• Inspect insulation and connector crimps regularly, and replace any worn terminals to maintain a safe connection.
• Use strain relief at bulkhead crossings to protect soldered or crimped joints from repeated flexing.
