([[User:Malcolm.chambers|Malcolm.chambers]] 03:31, 2 January 2010 (UTC) I'm pretty sure this is the box which has a label "this now works as you'd expect [##/07/09]"" and merely selects which of the two inputs goes to the output. If so then it's not as simple as it looks as it has two resistors in, for termination I expect.) | ([[User:Malcolm.chambers|Malcolm.chambers]] 03:31, 2 January 2010 (UTC) I'm pretty sure this is the box which has a label "this now works as you'd expect [##/07/09]"" and merely selects which of the two inputs goes to the output.

A metal box with three BNC connectors and a switch in it. The switch picks either of the inputs to connect to the output. The unused input is supposed to be terminated, although this doesn't appear to work reliably. In the obvious sort of way, can also be used backwards. | ([[User:Iain.cooke|Iain.cooke]] 12:27, 2 January 2010 (UTC) This label referred to the switch position, which didn't match the inputs: switch left = right input and vice-versa. This was re-wired to make positional sense.) | ||

It is named the C-E switch as it was originally used to swap between VTC (Umatic) and VTE (VHS) due to a shortage of mux inputs. | |||
