2-Port Physically Isolated Network Switch

Compact 2-port network switch with physical isolation between ports. Dimensions: not specified in source; weight: not specified; housing: metal case with nickel plating for corrosion resistance and electromagnetic interference (EMI) shielding. Supports three operational modes: (1) two hosts sharing one external network — only one host accesses the internet at a time, switched manually via push-button; (2) one host connecting to two external networks alternately; (3) two intranet devices switching between a single external network connection. Plug-and-play operation — no drivers or software required. Nickel-plated contacts prevent oxidation and contact degradation, ensuring stable signal transmission over time.
