What issues to pay attention to when purchasing metal shrapnel
12-08 / 2023

The metal shrapnel is made of stainless steel material and is an important component of the control switch. With the conductivity of the metal shrapnel, it serves as a high-quality control switch between workers and goods. At the same time, with the stable resilience of the pot slices (actively returning to their original position after pressing them down) and a longer service life, it creates high-quality tactile effects for the staff. Metal shrapnel is mainly used in thin film buttons for hard boards such as printed circuit boards.


What questions should everyone pay attention to when choosing metal shrapnel?


1. The service life of metal shrapnel: Nowadays, many metal shrapnel in our country have a service life that does not meet the standard regulations. The cross shaped metal shrapnel only has a service life of 200000 to 300000 times, and the price is relatively affordable. However, there are very few metal shrapnel that can have a service life of 500000 to 1 million times, while circular metal shrapnel, such as 4C and C5 smaller metal shrapnel, has a service life of only 700000 to 800000 times in our country, and the price is relatively low.


2. The working force of metal shrapnel: The working force of metal shrapnel is the most strict standard requirement of foreign customers, which means that the working force of the metal shrapnel used in each of your products should be uniform, and there should be no unevenness in the working force. It should be adjusted within the corresponding working force standard tolerance (± 20gf) range. However, the tactile sensation of various models and specifications of metal shrapnel in China is not stable, which has caused significant losses to some manufacturers of commonly used metal shrapnel. And lost customers for this.


3. Metal shrapnel production materials: In the process of manufacturing metal shrapnel, appropriate production materials should be selected and cannot be selected based on price. There are three types of production materials: domestic production materials, Korean materials, and Japanese materials. And each type of production material needs to be divided into multiple different production materials. In the eyes of real manufacturers, they are clear about which production materials are relatively good and what standard requirements can be met for the products they produce. The most obvious drawback of metal shrapnel is the dead key, which means that when the metal shrapnel is pressed in, it does not automatically bounce up, and the surface is difficult to see, which can only be detected after detection.


4. Appearance design of metal shrapnel: When purchasing metal shrapnel, it is important to pay attention to whether the appearance design of the metal shrapnel may have center points, dirt, scratches, oil stains, pressure marks, etc.
