Yokomo BL-RPX3SW speed controller power switch for BL-RPX3 series electronic systems  [BL-RPX3SW]

BL-RPX3 series power switch

This unit is a dedicated power switch designed for use with Yokomo BL-RPX3 family electronic speed controller setups in 1/10 scale RC models. It functions as the main power on/off interface between the battery and the electronic system, intended for model-level use only.

Installation is straightforward for experienced model technicians: place the switch in an accessible location on the chassis, secure it with appropriate fasteners, and wire it inline following the ESC and battery polarity. Verify connections before the first power-up and keep wiring clear of moving suspension or drivetrain parts.

In practical tuning and maintenance, the switch provides a convenient way to cut power during setup, transport, or while making adjustments trackside. It simplifies power cycling during testing and helps isolate the ESC and servo circuits when diagnosing electronics behaviour.
