Tact switch, also belongs to button type switch, as the name implies, when using a tact switch,When using the light touch switch, as long as you touch the button gently with your hand, the switch power can be connected, and when you release the switch, it will be disconnected, which is very convenient.Different tact switches are designed for different purposes and have different internal structures and specifications,common types include tact switch, patch tact switch, high insulation resistance tact switch, waterproof tact switch, dustproof tact switch, tact switch with lamp, normally open tact switch and normally closed tact switch.Do we have any methods for selecting from so many kinds? Here's a look at how to pick a switch:

1. Pin base material

The base material of the pin is generally brass or phosphor copper, the base material of the pin is iron, and the base material of the pin should be treated with silver-plating, after silver-plating, it will be treated with protective agent.

2.Conducting reliability

The contact surface of the contact point is determined by the structure. There are roughly three types of structures in the market. The advantages and disadvantages are as follows: big bubble (volcanic mouth), "O contact", "2 point contact" and "1 point contact".

3.Hand feeling and using life

Stroke or shrapnel contact sound determines the life of the tact switch,the shorter the stroke,the lighter the sound and the longer the service life.The stamping technology and materials determine the life of the shrapnel. The technology of Japan and Taiwan is mature and widely used in China,for example, the professional manufacturer of guangdong tact switch,XKB brand, uses stainless steel shrapnel imported from Japan and Taiwan, which can guarantee the service life of the switch no less than 100,000 times.

4.Packaging technology

The quality determined by packaging technology,

the packaging technology depends on the manufacturer's assembly method, as well as the company's management ability, quality assurance ability, and overall quality awareness of the staff.

5.Delivery inspection

The last step is to check the factory's inspection method. Is there any strict requirement for inspection? Is it spot inspection or full inspection?Whether the inspection procedure is perfect, whether there is a comprehensive inspection of the product from appearance to internal structure, these are the key factors for the quality of switch. Therefore, it is suggested to choose the major brand of a formal professional manufacturer instead of the low-price product.
