3 Way Switch 1 Light. We'll look at three different layouts depending on if you want the light fitting to be at the beginning, middle or end of the circuit. On the power coming in from the panel, you would connect that black wire to the one black screw.
Archaic light switches might as well be from the stone age. If you examine a three-way switch, you will notice several differences when compared to standard single-pole switches. In the first position, the contacts are connected straight through, so that the switch has no effect.
Understanding how the circuit works The electricity that flows through the first switch now finds a pathway through the second switch and the light is "on" as represented by the yellow bulb.
This scene is repeated in hundreds. maybe thousands of homes every evening.
Three-way light switches control a light from two locations, such as from both ends of a staircase or hallway. A three-way switch is built and wired a little differently than a conventional single-pole light switch. We'll look at three different layouts depending on if you want the light fitting to be at the beginning, middle or end of the circuit.
