Car front/rear camera switch
I currently have a media player in my car, and I'm thinking of installing a front camera to avoid scraping on curbs when parking in a lot. My dillema here is that after some reading, I'm not sure exactly how the actual wiring of the switch will be, as I'm also unfamiliar with the internals of an RCA cable. I opened up an extra cable, and saw that there was indeed a shield, with a wire in the middle.
To achieve what I want, can I use a DPDT switch? If my layout is like this on the switch
Would the shield on one cable go on say "1" and the middle wire inside the cable go to "2"?
Aaaaand in case you're wondering why bother with all this work and not buy an RCA switch... I only need the video lines to be switched, not the audio, so I don't need something bulky. The set up I have in mind will also allow me to place the switch in an inconspicuous location, such as the lower dash. Thanks in advance!
