I have an old 3/8" Skil drill model 599C whose variable speed trigger
is kaput, It is a hammer drill with a collar behind the chuck for
selecting normal drill or the vibrating "hammer" action.

The last time I went to the dealer this switch was replaced promptly
as this was a high failure item.. I think this drill model is no
longer manufactured and the dealer closed shop long ago.


Does anyone know which part in the swtich assembly can I replace to
fix it?
