This is the latest project I'm working on. An intervalometer would be similar to this switch, except
you add a timing circuit to it and put it in a nice enclosure. There will be more pictures later, as the project comes
This is a very handy cable for this project. Put a momentary switch on one RCA and a regular switch
on the other. One of the RCA ends is for metering and the other is the shutter release. Trial and error.
