Rotary source selector for audio

Commercial Input Selector Unit with ELMA 04 Rotary Switch wanted

There are many key words for such a thing.
Input Extender - Stereo Input Control Box - Input Switching Control - Source Selector - Input Expander - Line Selector - Audio System Selector - Input Channel Switcher - Source Expander - High-Level Switch or Input Audio Control are some examples.
Therefore it is hard, to find an overview for such devices.
Here you will find such a line up (partly the naming in German):

There are even a DIY (homebrew) version with ELMA 04 and RG316 coax cable:
http://forums.stevehoffman.tv/threads/know-of-a-great-sounding-analog-switch-box-rca-or-xlr.262857/

But I want to know such commercial devices, where the ELMA "04" is inside or the same rotary switch model under the brand name DACT.

Thank you very much for advices.
