Yep 450 Rancher. If the black and blue wire need to make contact, I'm wondering if that contact point was somehow bent away. There looks to be a metal piece beneath the trigger where that contact may be is supposed to happen. Will check that out.
Saw Won't Shut Off?

It's as simple as you explained. Took a while to get back out to the shop but I attached some pics. Both wires are connected and those connections cleaned. The contact point beneath the switch looks to make firm contact. Still won't shut off. 
Then something still isn't correct- either current is not travelling on the earth side or the contacts are not being made through something appearing to be touching that isn't or something being broken that is not allowing the trigger contact to find earth/ground.
Heres the thing- with the top cover removed- start the saw.
Let it idle and with a small screwdriver or similar, cross the two blade terminals at the ends of the wires at the red switch- if the saw stops- the issue is somewhere within the switch system.
If it continues to run with the two wires "joined" by your screwdriver- then the issue is between coil and switch- most likely a broken wire- that is the wire inside the insulation- insulation may still be intact. A likey suspect is where your blue wire attaches to the coil and then does a sharp 180 bend.
