What about the size of light touch switch? I think a lot of new beginners have less contact with the purchase, and the novice business with more trade should be more abstract about the size and specification of the switch, don't mention how to look. Today, as an old bird's editor, I'll introduce you for free. I remember that it's free, free and free. I'll say important things three times. Here, many people will ask how to determine the specification of the light touch switch. It is based on the length, width and height of the switch body to determine the size. Generally, we call it several times several, and the height is also matched. Next, let's take a look at the diagram, and it will be clear at a glance.

 

 

 

Let's introduce the specification drawing of touch switch?

 

1、 Position 1 in the above figure refers to the length of the switch. The unit of length is mm. We usually say that the length does not include the welding foot. We call it the foot distance if it includes the size of the welding foot. If it does not include the welding foot, we call it the length.

 

2、 Position 2 in the drawing refers to the width of the switch. The unit of width is mm. Generally, the welding leg of the switch is the length position, so there is no difference in the width position.

 

3、 Position 3 in the drawing refers to the height of the switch. The unit of height is mm. We all know that the light touch switch is divided into (vertical and horizontal). The vertical switch height is the height from the base of the switch body to the top of the key handle; the horizontal height is also the height from the base to the top of the handle, and the center position from PCB to the key handle is the center distance.

 

4、 Position 4 in the drawing refers to the key handle of the switch. The key handle is an important part of the switch, which is also indispensable. We have detailed description in the introduction of the principle of light touch switch. You can have a look at it when you have time.

 

5、 The No.5 position in the drawing refers to the foot distance of the switch. We have already explained the position of No.1 in the drawing, so I will not say more. Otherwise, Baidu said that I am wordy and won't let me go to the home page.

 

6、 Position 6 in the drawing refers to the wiring diagram of the switch. How do the two feet touch the switch? How is the four foot tap switch connected? We have detailed description of these in the wiring diagram.

 

7、 Position 7 in the drawing refers to the PCB wire size drawing of the switch. This is what we design electronic engineers pay more attention to. Without this, we can't draw anything. As long as we draw according to the size of the pad, it is recommended to draw according to our drawing. Do not increase it blindly, otherwise, there may be abnormal solder paste waste, ha ha ha.

 

8、 Position 8 in the drawing shows that the switches of dongkun conform to the global environmental protection standards such as reach standard of EU, halogen-free standard, California sixth five year plan, no use of abrupt metal products, RoHS and other global environmental protection standards. We also do something for the earth's environment. If dongkun electronic bearing only uses new materials, it will never use recycled materials, which is the principle of our dongkun people.

 

After reading, the specification of the light touch switch in our drawing is explained in the drawing. Let's take a look at how the Middle East Kun switch model is shown on the drawing? For example: gt-tc024x-h0060-lx

 

1、 The No.9 position in the drawing refers to the two English letters GT. GT is the abbreviation of the beginning of dongkun material number, and also the direct name is dongkun. So when you see the item number at the beginning of GT, you all know who it is. Ha ha.

 

2、 Position 10 in the drawing refers to the key strength of dongkun switch, which can be divided into: a = 160, B = 250, etc.

 

3、 Position 11 in the drawing refers to the height of the switch, the letter H is the beginning of the height, h0060 refers to the height of 0.60, and so on. I think you can understand it at a glance.

 

4、 Position 12 in the drawing refers to the service life of the switch, l is the abbreviation of life, L1 refers to the service life of 10W times, and so on. This is very simple and I will not elaborate on it.

 

5、 Position 13 in the drawing refers to the physical diagram of the switch. This is taken by dongkun electronics specialty. If there is no equipment or technology, please do not imitate it. Ha ha.

 

6、 Position 14 in the drawing refers to the detailed parameters of the tap switch.

 

The detailed parameters are as follows:

 

1. Operating temperature range: - 30 ℃ to + 85 ℃

 

2. Rated current rating: 50ma.12v DC

 

3. Insulation resistance: 100M Ω min.100v DC

 

4. Dielectric strength: 250V AC for 1 min

 

5. Contact resistance: 100M Ω max

 

7、 The No.15 position in the drawing refers to the stroke of the switch. The stroke of the light touch switch is generally 0.1 mm, 0.15 mm, 0.2 mm, 0.25 mm, 0.3 mm and so on, which can be designed according to different structures of products.

 

8、 The 16th position in the drawing is the light touch switch manufacturer. Of course, the logo of the manufacturer above must be our dongkun electronic. I think you can understand this logo very well. If you see it, you must be envious, jealous and hateful!

 

9、 Position 17 in the drawing is the detailed model of the switch, that is, according to our detailed description above, you can select the specific parameter code you need, and finally form the final model, that is, the product you need. You can give you the sample and product quotation very clearly as long as you directly tell us the business of dongkun, so as to avoid the intermediate inquiry and communication Ask the East and ask the West about the troublesome matters.
