This switch on (so far I have 2 weeks) but the copy I received was a manufacturing defect: it was apparently mounted upside and therefore catches do not match! I did not understand why my TV was not receiving signal when I was followed to the letter the instructions in the user manual (in English), and why it was the input of the diode 3, which then lit I had just connected the input 2 ... In fact the input 3 IS the input 2, and the true output jack (the one that connects the switch to the TV) is actually the input 1 and vice versa. Morality, it takes only rely on the ignition or not front LEDs to be sure the socket you connected, and not to the names that are registered above these sockets ... Now that I've found the thing and everything seems to work, I will not return, but the people who order this product must know the "risk" they take (hoping, of course, that this defect concerns only the unit I received!).
