As long as only one of the devices is on, the automatic switching is fine. But if two devices active, you can switch with the remote sources. Here is the small catch: If you put the supplied IR receiver to the switch, he responded not only to the supplied remote control, but also to the signals from the TV and receiver. Specifically: He switched repeatedly and uncontrollably in order, even if you wanted to change only once the volume on the TV (Panasonic equipment). I have now taken off the receiver. If you have to change, for example because the receiver is to record on, there's a button on the switch itself.
One more little thing: For some input signals, the switch makes a slight buzzing noise of itself. But that will only hear sensitive ears.
