Looking for the 2 small buttons. Held in by rubber base and stick through housing. Craftsman does not have a part or number. May be able to get a size later. They called this a Digi-Click so maybe Digi-Key sourced. Also used of Etrox wrench as well
Loose Tactile type switch for 9-13919 25-250 ft lb 1/2" Drive Digi-Click Torque Wrench
Welcome to the Technical Forum. We are a distributor and do not make parts. So unfortunately this is not something we made. I looked up instructions and information on this part. They do not list the size of the switch. The only thing I can say is you would have to remove it and measure it. Here are all the tact switches: https://www.digikey.com/short/541v82cz
You can start by narrowing down the size and apply filters. See what options you have to choose from. Sorry. This is the best I can offer at this time.
