Didn't go far enough, the problem with the trigger is that the internal contacts burn away with use and need to be cleaned / repaired. the trigger is no longer available so you have to fix it yourself. Difficult to repair the contacts, suggest you just clean them and put the switch back together. Check if it works with a meter before reassembling the saw. If not throw the whole thing away and mend it with a new one!
