2-Port Physical RJ45 Switch Box

A physically isolated, unpowered 2-port RJ45 network switch box measuring 77 x 50 x 20 mm and weighing ~50 g. Made from corrosion-resistant, anti-static ABS plastic with efficient passive heat dissipation. Supports dual-use configurations: either switching between two upstream network sources to a single downstream device, or distributing one upstream connection to two downstream devices. No ICs, no firmware, no latency — signal passes through unchanged. Widely deployed in UK financial institutions, universities, and SMEs requiring secure, deterministic Ethernet routing without network-layer complexity.
