Hi, I have a Sears Craftsman 90 series model #315.220900 1/2" electronic variable speed reversing drill that needs a new switch. Unfortunately the Sears parts website does nor have any reference to this model. I cannot find any replacements for this on ebay or elsewhere. Is there another substitute available? The FA5-4/1BEK switches on ebay have the exact physical dimensions as mine but I can't figure out if the connections will work. My switch is made by Teccor and has T3 stamped on the side of it. I have attached a photo of my drill.
