Switch when the power source runs into the light fixture before it goes to the switch. Glenn electrical technician replied 10 years ago.
How To Wire A 4 Way Switch
Power to light then switch. Note how the electricity is routed into the bottom part of the switch then out the top part of the switch to the light and then out the white wire from the light. The source hot wire is connected to a switch terminal and the other terminal is connected to the black cable wire. Run 142 with ground sheathed. Sofrom the power 142 line to the 1st light i will then put in 143 from 3 light boxes to switchwhat line is connected to each at the 3 light boxes and the switch electrician. Turn the power off at the breaker. Replace the 220 ac receptacle no longer needed with 110 receptacle 3.
The source is at the switch and 2 wire cable runs from there to the light. The hot black wire from the power source travels through the switch and from there to the light. The white wire marked black to indicate that it is a hot wire should be connected to the lower connector on the switch. If power comes into the switch box first the neutral white line from the service panel and the white line that leads to the light are spliced together. Id like to use the three existing cable runs which means the power will run from the panel to a junction then the light switch replacement receptacle see pic. You just want to put power to the switch then onto a light.
Install a light operated by a switch 2. Add another receptacle before or after the switch. Flipping the switch interrupts the flow of electricity to the light turning it off and on. You do not want the switch to control the outlet. Here a single pole switch controls the power to a light fixture.
