Multiplex Safety-Switch 12HV TwinBatt (MPX85009)

The Multiplex MPX85009 Safety-Switch 12HV TwinBatt is a compact, high-voltage FET switch harness designed for reliable receiver power in demanding RC models. Using vibration-proof SMD technology and low-resistance FETs, it provides fail-safe switching and efficient dual-battery management. Suitable for 4–6 NiXX or 2S LiXX receiver packs, it delivers up to 12 A continuous current with gold-plated connectors and robust cabling for maximum reliability.

Key Features
