I have a Sears model 113.197751 table saw (1979). Under heavy load it shut down and won't restart. The reset button did not pop out and does not "click" when pushed.

I pulled the motor and checked everything. The problem appears to be the rest button itself (p/n CGJ65EB). I can't locate the part on-line and Sears says motor work is a Service Center job.

Does anyone know if or where I can obtain this part? Thanks.
