I am finally getting around to installing the replacement switch I got from you for my Poulan 1625 electric chain saw. I quickly found that the safety button (push to release the trigger) won't go through the hole on the housing. In the parts list the switch comes in two parts implying that the button is shoved in and clicks to its final position through the housing. The switch I got has the button in place already. How do I get the safety button out of the switch without breaking it so I can put it through the small hole in the housing?
