USB 3.0 One-Button 2-to-4 Switch

A purpose-engineered USB sharing device connecting two host computers to four USB peripherals. Physical specs: 12.5 × 8.5 × 2.8 cm, 180 g. Enclosure made from impact-resistant ABS with soldered-in USB 3.0 receptacles for durability. Rated for 5 Gbps per port, compliant with USB 3.0 Gen 1 standard and backward compatible with USB 2.0. Offers dual power modes: bus-powered (via upstream hosts) or externally powered (5V 2A Micro USB input — adapter not supplied). Strictly USB data and power only — no video, audio or network passthrough. Operation is simplified to a single press of a recessed front-panel button, with LED illumination confirming the selected host (PC1 or PC2). Verified compatibility with Windows (7–11), macOS (10.14+), Chrome OS (v90+), and mainstream Linux distributions (kernel 4.15+). For USB-C laptops, correct functionality requires a USB-C to USB-A adapter with full USB 2.0/3.0 signal routing — generic charging cables will not work. Engineered for efficiency in dynamic workspaces: engineers debugging hardware across test benches, educators managing classroom lab PCs, or hybrid workers splitting time between company-issued and personal laptops — all while retaining full-speed access to essential peripherals without rebooting or reconnecting cables.
