Don't know inching even after removing the mouse?

Editor in charge: Popularity: 0 Published on: April 10, 2023【 large in Small 】

There are many kinds of touch switches. In the mouse, we call them "square inching", and the thinner ones are called "patch switches". They save more space than our common long inching, which are common in delicate small mice or side keys.

The size of this light touch switch is very small, which can greatly save the space in the mouse. However, we can see that the pin is very different from our common inching. The pressure grams are also hard enough. Our most commonly used Omron D2FC-F-7N pressure grams are 0.74N (75gf), so it is rarely used on common mouse buttons. And we can also see its shortcomings, that is, its life is slightly short, so it can save space and reduce its use frequency by placing it on the button that is not used frequently.
The size of this light touch switch is slightly larger, and the pressure gram is also slightly smaller. Note that it is slightly smaller, but it also has 130gf. However, the biggest attraction of this switch and the above two switches is that it has a much longer life, that is, it is more durable. The pin type is "S" line.

This kind of light touch switch has a small volume, and the contact part is covered with plastic, which can prevent rosin from infiltrating during welding. It is a fixed frame type, which can be directly inserted into the PCB board. It has a good touch feeling, and the buttons can have a variety of options. There are also grounding pin types, which are conducive to electrostatic discharge. In addition to being used in a mouse, it can also be used in electronic equipment such as telephones, stereos, televisions, etc.

It is also a square light touch switch, but the difference is obvious. It has a longer service life, higher reliability and wider application range. Let's take a look.
From the parameter point of view, the pressure grams of this kind of light touch switch are closer to our daily inching. The length and width of this series of light touch switches are basically fixed, the height is different, and the pin shape is also different.
The size of the switch is higher, and the pin type is the "1" shape we usually see, that is, straight up and down, which is more suitable for the commonly used mouse PCB board. The installation position is closer to the left and right buttons, which saves more space than the long strip inching. For example, the "double click button" in the upper left corner of the left mouse button is more narrow, and this kind of touch switch is most suitable.
158 series touch switch

The shapes of these two switches are quite different. You can't see them on the left and right keys. They are commonly found on the side keys and other positions. Unlike the Nagava Serpent of Razor, the switch uses a thin and light patch switch. Most of these switches are side keys with a small number, which have a relatively long service life and a guaranteed hand feel.

TTC's 158 series switches are small in size and light in weight, have a very good touch, and have an absolute advantage in price. In addition to the mouse, it is also commonly used in telephones, calculators, mixers, circuit breakers, battery chargers, stereos, cordless phones, alarms and other electronic equipment, with a wide range of applications.
