What Is 3 Way Smart Switch

What Is 3 Way Smart Switch. We all know how a regular switch works – switch it on or toggle it off. How smart switches work is a bit more complex, with 3 way switches providing the solution to locations like stairwells and long hallways. These are basically just switches that can control the lights from two different locations. For example, if you are at the top of the stairs, you can switch the light on or off from there. When you walk down the stairs ,you will see another switch that can be used to turn the same light on or off. For this reason, some people also refer to a 3-way switch as an upstairs/downstairs switch.
