How should properly be included Switch: up or down

Installation of the switch is carried out not only as handy (like), but also so that for him to be seen whether it is on or off right now. There are currently no regulations, which would have been clearly spelled out the correct position of the switch, and it must be switched on and off. In this article, we will focus on how to still have the right switch. So, let's begin.

Ka has been said, there is no clear-cut rules, but it is possible to draw an analogy with the existing switchgear. For example, Knife switches: Constructively they are performed so that the contacts are moving to the closed position when the handle is moved upward, and the open position provides transfer of the handle in the down position.

This is due to the fact that in the event of contingency "pull" the lever down much faster and easier than translating it up.

In addition, it is such an arrangement provides additional protection against accidental inclusion, for example, if it randomly will affect foreign object.

And in the position of circuit breakers is governed by the SAE regulations, and specifically paragraph 4.1.9, which reads as follows:

Let's look at the breakers, they are made in the following way: the location of the "flag" up indicates that the machine is turned on. This can also inform the labels and color coding.

A status flag "down" refers to the off position of the circuit breaker.

Thus, power is supplied from above and below the consumer is connected.

If you look at the machine AB, the power button is located at the top and bottom off button:

From this we can deduce the following rule:

Up - turn down - turn off.

Thus, the installation will be technically competent.

This means that light switches must be mounted in the same way.

But the modern market is flooded with a variety of designs switches: keyboards, sensor, rotary switches and futuristic. It is for this reason, before installing the need to scrutinize the documentation, which should indicate a normal switch position and orientation in space.

Let's say that a sign of good tone is a connection switch when the transfer key is turned on up and down keys transfer disconnection occurs.

conclusion

So, you can now answer the question in the title of this article: the switch should be included key transfer up. But it is not a tough recommendation, and, so to say, a rule of etiquette during installation.

You can choose your home is another option, the most important thing to the house observed uniformity, the is, if decided that you transfer switch turns the key down, then it should be all over house.
