Do not have a break in the ground wire! Do not run it through the ‘switch’ in a manner that it will break the ground circuit. Only attach the ground to the switch (at bottom) on the appropriate location to the ground circuit. The ground circuit should be run to the motor and ground the housing. The Idea for the 3rd line or ground is for safety. Do not ‘open’ it by connecting it to a switched terminal. If there is no line ground line going to the motor, you can run a 3rd wire there or simply clamp it under a bolt head on the table.

The other thing I suggest is to have a ground fault circuit. If the circuit you are using is not a ground fault, you can either change the plug to a ground fault or you can buy a ground fault adapter that plugs into the outlet (Home Depot ~$15) The ground line is your safety net. The ground fault is the policeman.

There is much to be careful of in a shop: blades, knives, toxic chemicals and electricity. Getting cut is one thing, severing a finger is a permanent loss, but electricity kills you! Use the best of the Knowledge Base available to you.

I want to caution you, I am not an expert. These are my understandings from using the switch you had a question for, and long use of electricity and machinery. If you are conflicted or unsure, hire a Licensed Electrician to review your setup. (Many will do it for little or no charge—sometimes just a cold beer!)
