Step 39: Video Switch: Jacks

Extract the RCA jacks. The kind that have left and right audio plus a video (red, white, and yellow) are the most convenient to work with. I got these from an "Elmo Classroom Presenter". I used other parts from it later in the project.

Find or purchase a 'single pole double throw' (SPDT), or 'double pole double throw' (DPDT) switch. This one is DPDT, identifiable by the six posts on the bottom. SPDT would have three. Both are OK.
