Looks like you might have to get creative when mounting the switch. To get that switch to work carefully drill a small hole through the PCB to accommodate the center leg and run a small jumper over to the pad where the old one went through. I just checked my game and thete appears to be room to do this. Im assuming the end legs line up properly with the existing holes?

Like I said in my previous post, make a hole to line up with that center pin.
