I’d like to add that hitting the off button should really make it turn off. The contacts got fouled on my delta switch and once in a while I couldn’t turn it off. I bought one of those cheap 20A 2 pole Chinese paddle switches on amazon. Haven’t had an issue yet.
Another tip if you replace the switch: you must bond the ground to both the motor and the table! To retrofit my completely different switch, I used a short piece of steel angle to connect the electric box for the switch to the table fence rail. Then I could ground everything right to the box itself, of course with a connection on the power cable to the wall outlet.
