2-Port RJ45 Network Switch Box

Compact 2-port RJ45 network switch box with physical dimensions of 77 x 50 x 20 mm and weighing approximately 50 g. Constructed from ABS engineering plastic for corrosion resistance, static protection, and efficient heat dissipation. Supports two operational modes: switching between two input sources to one output (2-in-1-out), or splitting one input to two outputs (1-in-2-out). Requires no external power supply — fully passive design ensures zero electrical interference and true physical isolation between connected networks. Ideal for dual-network environments such as corporate intranet/extranet separation, educational labs, or financial trading setups where signal integrity and network segmentation are essential.
