Last year when we totally remodeled one of our bathrooms, we had an electrician change the light switch next to the entry door. It used to be 2 vertical switches, one for the light and one for the fan. We replaced that switch with a combination gfi outlet and switch. The new switch has 2 horizontal switches stacked one above the other, and when he installed it, it was positioned so that the 'on' position is flipped away from the door, and 'off' is flipped towards the door. This seemed a natural way to have the switch go on and off. A short while ago, we had a different electrician do some work, in which he split one large looped electrical line into 2. During this process, he removed the bathroom switch, and when he put it back up, he placed it the other way, so that now the 'on' position is towards the door, and 'off' is away.
Is there any standard way to install horizontal light switches by the entry door? I preferred it when it was flipped on by pushing away from the door. Or, is this like toilet paper - rolling off the top or off the back is simply a matter of preference?
BTW, when we first bought the house, yet a different electrician put new slider and flip switches at the entry to each bedroom, and he also positioned them with 'on' away from the door.
