Dual Camera Switcher Relay Wiring Diagram - Left/Right Trigger to Video Recorder

This document is a hand-drawn/CAD-style electrical wiring schematic showing how a camera switcher unit is wired to a video recorder through two relays and a manual selector switch. The camera switcher has three output lines labeled Camera Switcher Power, Right Camera Trigger, and Left Camera Trigger, plus a Ground Rail connection. Two relays are drawn, each with normally closed (NC) and normally open (NO) contacts and a coil. The relay contacts route the Right and Left Camera Trigger lines, while the coils are energized via a three-position 'Left -Off-Right' toggle switch. The switch output passes through a 5 A fuse before reaching the Video Recorder connection. The diagram illustrates how flipping the Left-Off-Right switch selects which camera trigger circuit (left or right) is activated, allowing the video recorder to receive or trigger the appropriate camera feed. No part numbers, wire colors, connector pin identifiers, or vehicle-specific year/model information appear on the drawing. A reader can learn the logical wiring topology needed to build or troubleshoot a dual-camera switching setup with relay isolation and fused power to the recorder, such as an auxiliary backup/side camera system installed in a truck.
