Futaba FUEBA0323 High-Power On/Off Switch Harness for RC Receivers and ESCs  [FUEBA0323]

Robust on/off harness for dependable power control

The Futaba FUEBA0323 ESW-1J high-power on/off electric switch harness is an accessory designed to add a rugged manual power switch into the model battery circuit. It uses heavy-duty wiring intended to route higher currents safely between the battery, receiver and electronic speed controller (ESC) on electric models.

Made for straightforward serviceability, the harness gives a neat way to isolate battery power during transport, storage or pit-side setup without disconnecting plugs. Its neutral layout suits electric cars, planes and boats where a reliable manual cutoff is preferred.

Installation notes and practical tips:

• Choose an accessible mounting point on the chassis so you can cut power quickly during setup and handling.
• Route the harness from the battery to the ESC or receiver avoiding sharp bends and hot areas; secure the cable with ties or clamps to prevent chafing.
• Confirm polarity and connector seating before first power-up; perform a bench test with the model unmounted to verify correct operation.
• Apply strain relief where the harness passes bulkheads to reduce stress on soldered or crimped joints.
