I was looking for a switch allowing me to connect my TV box, my turntable and my DVD recorder / player on my stereo. I can finally listen to Internet radio on my chain. 4 buttons select the device used. The case is nickel, not too big, very discreet, it fits perfectly the description and picture. Only the back seems a bit fragile because when you connect the RCA plugs the panel moves a little. In fact the rear section is not welded in one piece as I thought. Well nothing too bad if you do not have fun in connecting / disconnecting devices continuously.
