There are a wide range of electric switches available in the market today. Fixing all the electric switches required for a room inside that very same room is the best option.
Switch boards should be arranged only after planning the height and position of their location properly. They should be placed at a height of 4½ feet from the ground. Make sure all the switch boards of a house are placed at the same height. The light above the stairs should be accessible from both the inside and outside. Use two-way switches for this.
