Please bear with me as I have ZERO knowledge about any circuitry. If someone can figure out what I mean, I want them to give me a parts list and where to get them only and I will put it together (hopefully). Ok, in my car I have a push button switch to operate my convertible top. I have to physically hold the switch for 12 seconds while the top goes through its motions until it is finished lowering. What I want is some form of timer on the switch that will allow it to operate for about 12 seconds once it is pressed. I understand the risks involved but I just want to know how I can go about accomplishing this. Thanks for any help.
