What does touch switch L01 mean?

Touch switch means that both parties can sense it after touching something directly.

The words about the 2501 on the touch switch are only represented, it is the first line, well, the meaning of the first line, he will normally mark it as the meaning of 2501.

Mo Kaiguo II Lu Ling is a very good switch, this switch is indeed very good in the lightness of the switch, and the feel is also very good, so this Thai trend is very convenient to use.

Brand model: bull switch.

System: G07K111C

Switch 1 means on, 0 means off. 1 indicates the closed state, when the switch electronic contact is in the path state, and the current can pass smoothly, then the equipment will be turned on. 0 indicates an open circuit state, when the electronic contact of the switch is not on, and the current cannot pass through it, so the device will not be turned on.

A switch is an electronic component that can open a circuit, interrupt current, or allow it to flow to other circuits. The most common switches are human-operated electromechanical devices with one or more electronic contacts. The "closed" of the contact indicates that the electronic contact is turned on, allowing current to flow through; The "open" of the switch indicates that the electronic contacts do not turn on to form an open circuit, which does not allow current to flow through.

Classified according to use: fluctuation switches, band switches, recording and playback switches, power switches, pre-selection switches, limit switches, control switches, transfer switches, isolation switches, travel switches, wall switches, intelligent fire switches, etc. Classification by structure:

Micro switches, boat-type switches, toggle switches, toggle switches, button switches, key switches, as well as fashionable membrane switches, point switches.

Circle means open. Circles and bars, that is, "1", "0", at first during World War II, in order to ensure the stable operation of electrical equipment, engineers needed to compile a set of general electrical equipment standards to unify the electrification equipment in various fields such as navy, army, air force, civil defense, logistics, etc. In particular, the marking of switches should ensure that soldiers and maintenance workers from different countries can identify and use them correctly after only a few minutes of training.

Some engineers came up with a simple solution: that is, the international binary**.

Since 1 in binary means on and 0 on and off on the switches, there are "1" and "0" on the switch.

The switch is one of the important components used to provide control, most of the equipment has a switch, so that people can use the equipment more easily, but also to ensure the correct use of the equipment and the safety of operation, can effectively control the state of the equipment operation, so that the equipment can complete the specified work. Generally, the switch is marked with 0 and 1, so which one is on and which one is off?

1. Which switch 0 or 1 is on.

Switch 1 means on, 0 means off. "1" indicates the closed state, at this time the switch electronic contact is in the path state, the current can pass smoothly, then the device will be turned on, "0" indicates the open circuit state, at this time the switch electronic contact is not on, the current can not pass through here, so that the equipment will not be turned on. When using, be sure to see clearly that the switch is marked for use.

Second, how to choose the switch.

1. Look at the quality.

The quality of the switch is closely related to the safety of household electricity in the future, so it is necessary to choose products with excellent materials, it is recommended to use the combustion test method to identify, excellent products have good flame retardant effect and are not easy to burn, while poor quality products are not only easy to burn, but also produce pungent odor.

2. Look at the feel in the woods.

You can toggle the switch to try the feel, high-quality products feel light, have good strength and elasticity, inferior switch springs are soft, the feel is not smooth, and it is easy to get stuck in the middle. Moreover, high-quality switches are equipped with protective doors, which cannot be inserted with one foot, and a certain amount of force is required for plugging and unplugging.

3. Look at the appearance.

The surface of the excellent switch is smooth and smooth, and the selection of the shed orange land is imported PC material, without concave and convex points. Inferior products have a relatively coarse texture.

4. Look at the portion.

When purchasing the switch, you can also feel the weight of the switch by hand, and the high-quality switch is made of copper chain inside, so it is heavier. However, some manufacturers cut corners and chose alloy or thin copper sheet manufacturing, which is relatively light in the hand.

<>0 means disconnected, and 1 means on.

On appliances, 0 means disconnect. 1 means on. In logic circuits, 0 stands for low potential, and "0" in binary. 1 stands for high potential, the "1" in binary

1. The switching quantity is on-off signal, passive signal, and the resistance test method is resistance 0 or infinity;

It can also be an active signal, the professional name is a step signal, that is, 0 or 1, which can be understood as a pulse quantity, and multiple switching quantities can be composed of digital quantities.

2. Digital: There are signal types composed of 0 and 1, which are usually regular signals after encoding. The relationship with the analog quantity is the quantized analog quantity.

3. Analog quantity: continuous voltage, current and other signal quantities, analog signal is a signal whose amplitude changes continuously with time, and it is a digital quantity after sampling and quantization.

4. Pulse quantity: the signalamount that jumps from one value to another value in an instant. After quantization, the change of its continuous law is a digital quantity, and if it changes from 0 to a fixed value and remains unchanged, it is a switching quantity.

I have to use switches and sockets in our lives, and the main role is to connect and disconnect circuits, in addition to the function of decoration. As we all know, there are 1s and 0s on the switch, so what do these symbols represent? How to choose a switch?

Let's take a look.

1. Which switch 1 or 0 is on.

1 represents the open state, at this time the switch electronic contact is in the on-on state, at this time the current passes, the device will also be turned on, 0 represents the open-circuit state, the electronic contact in this state is not on, the current cannot pass through here, so that the device will not be turned on. In the process of use, we should clearly see that the switch is marked for use.

Second, what are the switch purchase skills.

1. Look at the appearance.

The switch is composed of an outer frame, an inner frame and functional parts, and the high-quality switch feels smooth, flawless and has the advantages of flame retardant, anti-twist and anti-impact.

2. Look at the portion.

When buying a switch, you can use your hand to check the weight of the switch, the copper sheet inside the high-quality switch is thicker, so the feel is heavier than the base li, the copper sheet inside is the most critical place for the quality of the switch, and the alloy and the thin copper sheet will not have the same quality and quality.

3. Look at the feel.

Excellent switch for better connection of internal contacts, the spring material is relatively hard, the key has a sense of strength, and the bad switch is softer, the sound sounds no crisp, the socket jack must have a safety protection door, plugging and unplugging requires a certain force, can not be unipolar insertion.

4. Look at the packaging.

**The switch packaging is clearly indicated with the manufacturer's address**, product certificate, and through the national mandatory 3C certification, the outer packaging specification, professional, unified, and the inferior product packaging is made of rough material and low material. There is no protection for the product.

Conclusion of the article: The relevant content about which switch 1 and 0 is open is introduced here, I hope it can help you. If you want to know more about it, please continue to pay attention to Qeeka Home information platform.
