How Many Rulers Are Needed To Make A Membrane Switch?

Some people may say that there is nothing unusual about rulers being so common in daily life. As long as a normal person is a ruler, he should know how to use it. But the editor discovered that in the production process of membrane switches, more than one kind of ruler is needed.

First, let’s talk about the steel ruler that everyone knows. There are straight steel rulers and rolled steel rulers. Steel rulers are mainly used to measure the length and width of materials, straight steel rulers are mainly used to measure small points of materials, and rolled steel rulers are mainly used to measure materials whose length and width are greater than one meter. The relative accuracy of the steel ruler's measuring distance should generally not be less than 1/3000, and it is a measuring instrument that is not too precise.

Next, I want to talk about the film ruler. Is there anyone like the editor who thinks this product is unfamiliar when they first hear it? The film ruler is a more accurate measuring tool than the steel ruler. In the use of membrane switches, film rulers are generally used for sample preparation to detect whether the produced product is consistent with the design sample. In this way, better and more accurate membrane switch products can be made.

Finally, there is a measuring tool called a caliper. The accuracy of the caliper is relatively high and can be used to measure the thickness and cross-sectional area of materials, as well as hardware accessories and some small accessories. It is basically used in general custom-made membrane switch factories.
