You won't have to unplug the microphone and plug in your TNC every time you want to work packet or other data modes.
Just plug this pre-wired cable switch box into your rig's microphone connector and into your TNC and you're ready-to-go -- no more hunting for hard-to-find connectors and wiring up complicated cables.
