Hobbywing Electronic Power Switch For Fusion

The Hobbywing Electronic Power Switch for Fusion (Part No: HW30850030) is a high-reliability replacement part specifically designed for the QuicRun Fusion series (including the Fusion SE and Fusion Pro). Unlike traditional mechanical switches that can fail due to vibration, dust, or moisture, this electronic switch uses solid-state circuitry to control power, making it the ideal choice for rock crawlers and trail trucks that frequently encounter harsh environments.

Key Features:

• Solid-State Reliability: Eliminates moving internal contacts, preventing the common issue of the vehicle shutting off mid-climb due to "contact bounce" or mud ingress.
• Integrated Set Button: Features the critical "Set" button required for calibrating the ESC to your transmitter and navigating the basic programming parameters without a program box.
• Waterproof & Dustproof: Fully sealed to match the IP67 rating of the Fusion motor/ESC unit, ensuring the entire system remains submersible.
• Easy Installation: Features the proprietary Hobbywing 3-pin connector that plugs directly into the internal switch lead of the Fusion system.
• Long-Life Design: Rated for thousands of cycles, the soft-touch button provides a tactile click that remains consistent even after exposure to silt and sand.

Important Calibration Note:

When replacing this switch, you must re-calibrate your Throttle Range. To do this: Hold the SET button while turning the switch on, then follow the standard Hobbywing procedure (Neutral -> Full Throttle -> Full Brake) to ensure the ESC correctly recognizes your transmitter's signal. If the button feels "sticky" after a muddy run, simply rinse it with fresh water while pressing it repeatedly to clear out any trapped grit.
