Table Saw

If it's the same click every time you turn it off, it's probably the centrifugal starting switch resetting.

Most motors have a centrifugal switch to control running capacitors. As the motor slows down after power off, the centrifugal switch disengages. Its unnerving, if you don't know what it is. I always thought it sounded like the blade hitting something under the table and expected find carbide chips under the table. After a year of nothing bad happening, I finally got used to it. By the way, I can't say I've noticed the click since I converted the saw from 110v to 220v.

Well, I thank you all for the information. Now I need to change out those pulleys.

Is it just a single click? If so, it's probably the starting switch contacts inside the motor and nothing to worry about.

You need to be a little more specific about "clicks" and the type of machine.

My old Craftsman used to click a little as the blade was running down. It was my que to tighten the belt pulleys.
