Quoted from Mark_Arts:I'm going to manually go over all the switches again.
Quoted from ForceFlow:Did you test the switch with a multimeter? There could be a short, such as a screw shorting the two leaf blades together.
Use a multimeter to verify that they are not shorted. Just because you see a gap, does not necessarily mean that they are "open". As ForceFlow mentioned, there could be something shorting it that you may not be able to see.
