Curious if anyone knows of a good 2-to-1 Video Switching unit that is relatively small and works well.... I am not looking for something with a built in toggle switch or remote or anything... I want to send a + signal to the unit to tell it to switch to source 2 and a - signal to switch to source 1 or vice versa.

My only idea was to get the PAC device that switches 2 AUDIO sources like this.. then get a few Y splitters and funnel my video source thru the unit that way.....

Any other suggestions?

If you are only looking to switch between 2 sources then you could just use some regular relays.  Send the relays a positive signal via remote wire or whatever and it will switch to the other video feed.

I don't know how you are going to handle audio but, an easy way is to use 2 FM mods.  You can also use the relay trick on the audio signals but, that's alot of relays. 2 relays per RCA!
