Intimidating pinball absolute dating of rocks and fossils
But there’s another configuration you can see: In this example, you can see there is a switch to the left that is “Normally closed”. It’s going to conduct electricity unless the switch is moved. What happens if we close just one of those switches? In this case, we just need one of those two switches to close.
Press reviews - IM: " Solar Wind's "Five Sheets to the Wind", has attracted a loyal audience both for their recording and their live performances in their hometown of Houston, Texas. , I think, much clearer discussion than trying to write it all out, and a different discussion on schematics.When switch contacts touch, they conduct electricity. For the light to be on, there HAS to be a complete circuit (no gaps) between the light bulb and the battery. The old electromechanical pinball machines, for the most part, use alternating (AC) current.I discuss that a bit more in the video, and draw out an example of the overall schematic.But if you take the diagram above, and cut off the battery, you get this: Notice how this looks quite a bit like a pinball schematic?
