Light Switch Mounting: Up or Down Position, Trends, Standards, and Installation Guidelines

I have a trivial but I think a matter-of-fact question. How should the light switches be mounted? They are to be turned up or down.
Is it just a matter of a trend or is it regulated by some standard

I do not know if it is regulated by a standard, but I remember when I was in a construction site where I did automation, an electrical installation inspector ordered an electrician to move all the switches so that the light was turned on after pressing the lower edge of the switch ...

I was a bit surprised by such an order ... But after this fact I noticed how such switches are mounted and in 99% of them they are mounted as ordered by the inspector ...

There are no and never have been any standards in these matters.
However, I have encountered a recommendation that, for example, the lift switches in staircases should be installed in such a way that when turned on, the * lever * is at the top. This was explained by the fact that when turned on the reverse, the weight * of the lever * in the upper position as turned off, could accidentally fall with its weight and activate the circuit.
They were old * knife * switches.
I didn't notice any rules with the key breaks.

I also personally assemble the switched-down ones and most of my electrician friends. But there are also supporters of the reverse version, and we almost did something on the construction site. Dloatego, I want to approach this matter substantially and explain it.

Hello,

My foreman from the Guild of Various Crafts (pre-war) gave me many "golden rules" that work to this day, including:
-do not believe anyone, especially yourself - check DISCONNECTION 2 times!
- always switch it on with the lever up!
-check the covers with the OUTSIDE of your hand!
-if you are looking for a short circuit in the circuit, switch all the switches of this circuit ONCE!

I have never inquired why this is so (upwards) but it seems to me that it is related to the natural human reflexes, a wave downwards means negation.
At that age, an exclusion was used. Lever (resembling overcurrent breakers, e.g. S301-attached top)

Maybe there is actually a standard for it?
Or is it "Good Practice"?

greetings

There is no standard, because what to do with staircase and cross switches.

The matter is simple, if the switch in the off state will stick out with the upper part of the flap, dust will collect there, and when the lower one sticks out when it is turned off, the dust collects only when turned on

Hello.
This topic was discussed at the SEP Forum, and probably also at Elektroda. There is no standard, but switching up is assumed, as well as in the sockets the phase on the left side, the pin up.
Greetings.

Mates. Exactly that there are standards that regulate it. Take a look at PN-EN 894, PN-EN 61310. In short, it looks like this:

The activation or increase of the parameter is always:
- if the buttons are vertical, then the top one
- if the buttons are horizontal, then the right one
- if the button is pressed bistable, it is forced to inhale
- if there is a knob, turn it to the right
- if there is a lever, it is up or to the right.

and a few more cases I just don't remember.

switches should be built in such a way that a person
standing before tipping over (or falling) hitting a switch turned it off.

But neither of these cases can be applied to the most popular home lighting switches.

Honestly, he convinced me the most jacur .

I have the opposite of what Col. Kaputo suggests. It turns down. I enter the room, it is dark. I am looking for the switch with my hand on the wall rather from the top, so it's more comfortable for me. I will always ask the client if he prefers. I prefer not to fall over there.

Hello ! An old and trivial problem! It is important that they are all mounted the same! This proves the diligence of the contractor.

it's good to go down and it's better that everyone should always do this because the problem appears when there is no light and we have to go somewhere, if we do not know it, it will turn out that after coming home we had all the lights on, and if we were not there 2 weeks it cost us a little extra

Summing up, no matter how the "up" and "down" supporters are, the only argument I have heard about this is the one Jacur quoted about the dust collecting. You could conduct a poll on this but as for me "down" For ever!
