E-structural formula / switch

E-structural formula
E-structural formula

we often press the wrong button when using the switch. E-structural Formula helps us ward of such mistake, taking advantage of human's touching feeling memory.Different colors, sizes, shapes and bumps
keep on reminding us of which button controls which lamp, which button controls ventilating fan,ect.The blue is fan controller, the yellow is major light(used most frequently) controller and the red for the adornment light.
The yellow links the wires, and connects them with the smalls.
The switch is made of plastic. Indicator lights are also needed.For more variation, glass,wood,rubber can also be used for making the button.
