Even though the Craftsman 610929-000 switch is no longer available from the manufacture. You may want to try link removed. They have a good variety of power tool switches that some of the tool manufactures no longer supply.
I have a Craftsman Scroller saw and looking for the speed switch P/N 610929-000. It shows as not available. Are there any still around? Would like to purchase one ASAP. Please contact me. The rest of this tool is in perfect condition and would like to keep it. Thank you.
