Knee-jerk reaction for tablesaw safety

You're making a cut on your tablesaw when, halfway through, the workpiece goes askew. Yet you can't shut off the saw without taking your hands off the workpiece. This situation can pose a major shop safety problem.
Buy a safety switch that pulls out for the "on" position and pushes in for the "off" position. Mount the switch on the front of your tablesaw at knee height. Now, turning off your saw is as easy as pushing your knee against the switch. These switches have an added safety feature: Each comes with a plastic key that you can remove to keep little ones from turning on your saw.
