Flipping the switch interrupts the flow of electricity to the light turning it off and on. Idealy connect white to top terminal black to bottom terminal bare ground to green screw on switch reinstall switch restore power and test by turning switch on.

If the line carrying power comes into the light box first the circuit must still be wired so the switch interrupts the black line. Simply strip the wire to the length specified and push the wire into the hole. They have two screw terminals plus a ground screw. It could be there is or once was a three way switch in play.

Connect the last switch in the usual manner looping the wire around the screw in a clockwise direction.

The hot black wire from the power source travels through the switch and from there to the light. I m trying to install a motion sensor light switch that is a replacement to a standard one.

In this picture you can see the strip gauge on the back of the switch. One screw terminal is for the hot wire that feeds the switch from the power source. I know which one is the ground. The hot wire in a 120 volt residential ac circuit usually is coated with black insulation while the return or neutral wire is white.

To connect the switches simply score the wire with your wire stripper and push the insulation to expose about 3 4 in. The other terminal is for a second hot wire called a switch leg that runs only between the switch and the light fixture. There are three wires.
