This item that will allow you to mount a Sescom 3.5mm A/B Audio Swith to a camera's cold shoe (with a 1/4 inch cold shoe adapter and 1/4 inch nut). This will allow you to switch between two microphones/audio sources for you video shoots. There is also a universal cold shoe on the mount that will allow you to connect additional gadgets (such as a wireless microphone receiver.)
The print shown in the photo is of the prototype. The current version of the model has a few small changes that will improve the way the A/B switch fits in, and improve the cold shoe mount.
