This creation is about a load switch system, especially a linked load switch system.

There are lights in the stairwells on the upper and lower floors of the existing house or building, a three-way switch on the upper floor, and another three-way switch on the lower floor. The two three-way switches are electrically connected in series to the illuminator. Whether the user is on the upper or lower floor, the three-way switch can be manually operated to light or extinguish the light.
