If you plan to install the switch in a room where several other switches have already been installed, refer to the height at which the other switches are mounted. This is to ensure that your switch does not drop out of the general level.
You need to mark up for wiring. The wiring always goes from the switch to the outlet or to the junction box. At the same time, the wiring should go from the bulb again to the junction box or to the outlet.
