Home lighting switch up or down, is there a standard

Generally, the switch is turned on when pressed down. Requirements for household switches:

Quality; Switches and sockets are related to very important issues such as daily electricity and safety, so quality is the standard, whether the switch is open or down is the first consideration. The so-called quality, first of all, to consider the durability of the product itself, the qualified pair of household switches on the market is generally more than 40,000 times, some big-name brands will be higher.

Most of the switches are on/off.

with the electric switch. The criteria for use are the same. But it depends on whether the switch is single or double control, if it is a single empty, then open and close; The dual control is controlled by multiple switches to control a lamp, so it depends on which output the switch is connected to.

There is no set standard. Most switches on the market are pressed down to turn on and up to off.

In the International Electrotechnical Commission standard IEC60601-1 (2005), there are certain constraints on the operating direction of electrical switches, for example, the knob rotates clockwise to increase, counterclockwise rotation to decrease, the switch toggles up or slides to increase or open, down toggle or slide to decrease or close the output.

Relatively standard products are pressed down to open, up to press is off, this operating logic, is a convention in the industry standard.

According to the habit, it is open up and closed downward, but there is no mandatory requirement, if it is an air switch, it must be open up and closed downward, and this has a regulation.

This is a very early book, 50 years ago there were regulations, the lighting switch installation up for the on, down for the off, the duplex switch is not directional, this is the requirements of the power equipment installation manual, after the power failure, I don't know whether the switch is on or off, to prevent sudden calls, in order to use electricity safely.

I don't know if there are any regulations on the standards for light switches? Let some people who don't understand the principle of electrical appliances talk nonsense! Put the switch upside down, and you are already an electrician, are you worthy?!! What a shame!

As for whether the switch of the electric light is turned on or turned on downward, I don't know if there are any mandatory regulations. Because according to the electrical operation and the relevant acceptance specifications, there is no clear indication of the direction of opening and closing of our switches. So the personal point of view is that the lights should be turned on downwards and turned off the lights upwards.

Specifically, there are three reasons for this.

At this stage, most of the wiring of the switch of the lamp is above the switch.

That is to say, the terminals are all in the upper part of the switch, and when we wiring, we generally wire from the upper terminals. The contact of the switch should correspond to the terminal block. So under normal circumstances, the contacts should be kept open.

Then if the contact is to be disconnected, it means that our upper should not be the disconnection point, so we can only turn on the light when we press the switch down.

It also has a lot to do with our usual usage habits.

Many of our friends usually press down less when they use the light. It is estimated that many friends have the same usage habits as me, that is, to press down on the panel of the lamp to turn on the light. So, in this sense, it's also the light on.

In fact, we can also judge the switching status of the light through other methods.

Because now there is generally a sign on the switch button panel of the lamp, some are horizontal signs, some are vertical signs, here the signs have a fluorescent effect, and can slightly emit bright light in dark situations.

We can turn on the light according to the place where we follow the sign, so this position is the part where the light is turned on. Therefore, we can also look at this part to determine whether it is open up or down, so as to determine how it corresponds to our lamp.

According to the regulations, up is on, down is off. Because, if you are repairing the light and the upward is off, when something slips on the wall and hits the switch, it may be turned on, so it is right to turn it down.

The single-control switch usually pops up at the top to turn on the light. The dual control switch can be switched on and off in both positions.

Press down Yes On, there is a sign on the socket.

Dear, I am glad to answer for you: the general household light switch is pressed down to turn on the light or press the top is on or offAnswerThe general household light switch is pressed down to turn off the light. Switches such as circuit breakers and knife switches have unified regulations, all of which are buttons up to open, and down to turn off.

This is done to prevent damage to the internal spring of the button, which cannot be stuck when it is opened upwards, and the button will automatically fall off due to gravity. If the switch button is turned on downward, it may cause the switch to close automatically, resulting in a risk of electric shock. Precautions for the use of electric lamps: The rated voltage of the bulb should be consistent with the power supply voltage when in use.

In order to make the light emitted by the bulb be well distributed and avoid glare, it is best to install a moderate lampshade according to the requirements of the degree of laughter. When installing high-power incandescent bulbs, it is necessary to consider good ventilation to avoid overheating of the bulb and causing the glass shell and lamp mouth to loosen. When the bulb is used in the open air, there should be rainproof facilities to prevent the bulb from breaking and being damaged in the rain.

The switch of the lamp is on when pressed down, generally the switch of the lamp used by us is the kind of small square switch, when we press down that is, down to the bottom, and up to the top, the switch at this time is on, the light is on, when we press up that is, the top is down, the top is up, the switch is off, that is, the state is disconnected, the light is out at this time, of course, there are many types of switches, but probably this is the principle.

Usually the household light switch, my house is down is to turn on the light, up to turn off the light. I'm used to it, and I think it's pretty handy.

This is not necessarily, this is related to the direction of installation, if the switch is placed on the top, it is to turn on the light upwards, if the switch is placed on the bottom, it is to turn on the light downwards, and the specific problem should be analyzed.

Usually up is to turn on the lights and down to turn the lights off. In general, people are more accustomed to groping upwards when they are groping in the dark, and according to this habit, the switch is set to open upwards.

The first point is generally to turn on the lights upwards and turn off the lights downwards. The second point is that some family lines may not be the same, or they may be the opposite, depending on the situation.

Single-phase one-position switch: suitable for single-phase AC 220 volt voltage, there is only one switch on the switch cabinet. For example, there is a light in the bathroom that is controlled by a switch.

Two-position switch: There are two switches on the panel. For example, the bathroom has a lamp, an exhaust fan.

the same circuit), which is controlled by two switch buttons on the panel.

Three-position switches: There are three switches on the panel.
