Wiring problem

Hello,

I'm a noob at electrical wiring and encountered a problem after I thought I finished wiring the Filastruder. When I flip Switch 1, the PID turns on, put when I flip switch 2, there is a small shrill noise and the PID turns off. When I flip switch 2 again, the PID turns back on. I believe I've done the wiring correctly but obviously I'm sure it's a wiring problem. I've attached a picture of the one thing I may have differently than the instructions. Instead of having a wire from Switch 2 to the fan wire and a wire to In(+), I've crimped those two wires together directly with the spade connector. I believe this is the same as if I had an extra wire going out from the center of Switch 2 but I may be wrong. If more pictures would help, please let me know.
