I spent ten bucks for the foot switch from Harbor Freight, the Delta has the controls under the left side of the table, and I wasn't comfortable with that. It was ten bucks well spent, if a blade breaks or comes out of the clamp, I automatically jerk my hands away and my foot off the switch. You have to hold it down to cut, and it shuts off as soon as you lift your foot. I find I hold my other foot up like the other guys, and I think it is a tension thing, I have to consciously relax my foot, then I realize I'm tense elsewhere too, so I stop and get up and walk around for a few minutes to relax, then go back to the saw.
I can look up the model number for the switch if anyone wants to know. They have 2 models.
