Need a ps/2 switch.

[houkouonchi]

Basically I need a simple device that can take a single PS/2 keyboard input and electrically switch between two output ports. Kind of like a KVM except I want one for just ps/2 and I would rather not use a KVM as I want something that is not going to do any emulation or cause latency or other issues with the keyboard input.

I play rhythm games like stepmania so keyboard latency/consistency is kind of important.
