How To See The Model Of Tact Switch

One,the size of the tact switch

You can directly use vernier calipers to measure the overall length, width and height of the switch. The type of the tact switch corresponding to different sizes can be roughly locked in the model range. Through the function and appearance, you can know the model.

Two, through the tact switch’s performance application

Basic is divided into three categories: the performance of the tact switch, conventional paragraphs ordinary and waterproof and resistance to high temperature, normal structure belongs to the conventional type, but not waterproof, high impermeability of waterproof, no cracks, basic is integration, high temperature resistance is the main material of high temperature resistant, this is not easy to see, can only use soldering iron is under test.

Three, according to the force

Different models of pressing cleft is different, there are 160~300gf cleft choice;

Four, according to the appearance of the style

According to the terminal form can be divided into: pin type, patch type. According to the packaging method, it can be divided into: bulk manual plug-in, SMT patch packaging, DIP plug-in ribbon packaging.

Through the above three kinds, we can roughly judge the type of the tact switch. So, if we just see the type of tact switch, how to judge the tact switch is which? At this time, it is to use the inverse method. The number of 160~300gf represents the pressing of the light touch switch, the first part of the two models, most manufacturers are on behalf of what is the product, such as useful TS on behalf of the tact switch,SS means slide switch and so on, and then the size of the tact switch is generally divided into: 6*6*5mm, 6*6*4.3mm, 6*3.6*4.3mm, 3.5*6*4.3mm and other such sizes.
