Basic materials are the components that go into the flush-mounted box, excluding the rocker and frame. From the V1 series, there are two-way, double, intermediate, rocker, and blind switches, as well as socket outlets, including those with USB and USB-C.
First, choose the basic element that matches your circuit. For a light operated from two locations, you need two two-way switches; for three locations, an intermediate switch is added in between. Afterward, choose the rocker and frame in the color of your choice.
