1. The independent 3-position switch uses 2 channels, a self-locking mechanical switch, and each switch independently controls an output. 2. Coarse-grained pins and strong conductivity. Each output is equipped with 2 large filter capacitors to ensure stable power. The input is connected to the host computer's power interface, and the standard SATA power interface is used. 2 inputs ensure sufficient power. 3. Backlit digital number LED design. When the switch is pressed and turned on, the corresponding LED lights up the number, and the status can be observed from the side. 4. The convex edge card position design increases stability and can be installed in the PCI or PCI-e slot, which plays a role in positioning and prevents swaying. 5. It is suitable for controlling multiple hard drives, switching multiple systems, optical drives, fans, RGB lighting effects, etc. The electrical equipment in the host computer is controlled and managed on the back of the chassis, which is discreet, safe, convenient, and aesthetically pleasing.
