First off, once again, I want to say thanks for all the help. I'm having to work on this thing a few minutes at a time, so its taking forever! I did get the soldering done on the Canon OWL PF. I couldn't have done it without yalls help! My question today is: On the bill of materials, it shows either 2 DPDT or 2 SPST. I bought 2 SPST switches. When I looked closer at one of the diagrams, it shows one of each. I just want a switch to control the LED test light and one to turn the system on and off minus the LED. What switch or combination do I use and how?
