Sorry should have mentioned how i was actuating the switch, with my pinky finger i grab and make a fist, that was working perfect untill 2 days ago. Since then i have marked a spot on the bottom button and rotated it to try and find a sweet spot, some positions dont fire at all, most weak and 1-2 fire perfect. so it seems as if somwhere in the switch there is a high spot makeing better contact, I cannot confirm this ATM because I am in TN and my micrometer is FL :-(.
