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.) On this version, there is also a small bar on the side that will allow you attach clip on gadets (such as clip on a wireless microphone). If the clip on bar is not needed pleas check out regular version.
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.
