Light Switch Grounding and Position
How to Locate the Ground Screw and Positioning The Switch – The ground wire must be attached to the ground screw on the light switch. The ground screw location may be different with different brand switches.
The Ground Screw and Positioning the Switch
Electrical Question: Where should the ground wire be positioned on a switch?
- I have a 2-way switch in a bathroom with an exhaust fan, all the wires are black.
- Should the ground wire go on top left or lower right, or I guess I should ask, what should the orientation of the switch be?
This electrical wiring question came from: Edward, a Homeowner from Houston, Texas.
Thanks for your electrical wiring question Edward.

How to Locate the Ground Screw and Positioning the Switch
- The ground wire must be attached to the ground screw on the light switch.
- The ground screw location may be different with different brand switches.
- Most switches have the “TOP” orientation stamped or printed on the switch frame.
- If the label or position is not given then it really will not matter and the orientation is up to your personal preference.
- For the sake of being user friendly and avoid confusion the up position is typically the ON position for single toggle switches.
- Don’t even worry about three way switches because the switch position changes when ever it is used.
- With flat panel switches or smooth face touch switches you still need to know which end is On due to touch travel.

The Safest Way to Test Electrical Devices and Identify Electric Wiring!The Non-Contact Electrical Tester
This is a testing tool that I have had in my personal electrical tool pouch for years, and is the first test tool I grab to help identify electrical wiring. It is a Non-contact tester, [amazon.com], I use for the detection of Standard Voltage in Cables, Cords, Circuit Breakers, Lighting Fixtures, Switches, Outlets and Wires. Simply insert the end of the tester into an outlet, lamp socket, or hold the end of the tester against the wire you wish to test. Very handy and easy to use.
