3-Channel Video Switcher Module for FPV RC Drone Camera Selection

3-Channel Video Switcher Module for FPV RC Drone Camera Selection is an ultra-lightweight electronic video routing switch engineered for multi-camera FPV (First Person View) model aircraft, quadcopters, and remote surveillance systems. Controlled directly via a standard 3-position toggle switch on any RC PWM receiver channel, it permits seamless real-time switching between 3 independent analog composite video camera inputs feeding into a single FPV video transmitter (VTX).

Key Features:

• 3-to-1 Analog Video Routing: Connects up to 3 individual composite cameras (front, down, rear) to a single FPV transmitter.
• PWM Remote RC Control: Plugs directly into an auxiliary receiver channel and switches inputs using a 3-position transmitter toggle switch.
• Zero Latency Switching: Ultra-fast high-bandwidth analog solid-state switching guarantees zero frame delay or video dropout.
• Lightweight Compact Footprint: Minimal mass and miniature form factor designed specifically for micro racing drones and fixed-wing UAVs.
• Camera Power Pass-Through: Passes continuous power and ground rails to each connected camera without requiring separate distribution boards.
• High Signal Integrity: Low internal resistance ensures no video signal degradation, ghosting, or color distortion.
