How to remote control switch between 2 video signals?

One of our customers says he’d like to use remote control to switch between 2 video signals. We recommend him 2 channel dc latching remote control model of 0020023 (S2L-DC12 & C-3). It has two channels, working with latching mode by 3-button remote control.

See the following wiring diagram. Two lines of input device (such as camera) is connected respectively to two NO (normally open) terminals C. Two lines of common terminal B is shortened together as a video output line. Then the video output line is connected to the output device (such as computer monitor).

Press remote button C, switch signal to video 1.

Press remote button B, switch signal to video 2.

Press remote button A, switch off the signal.
