There are many types of touch switches, which can be divided into direct plug-in touch switches, patch type touch switches, side horizontal touch switches, waterproof and dustproof touch switches, ultra small and ultra-thin touch switches, silicone button touch switches, silent touch switches, and normally closed touch switches. A light touch switch refers to a momentary small current switch that is only in the ON state during a press operation. Its characteristic is that it can be restored (tactile) upon sensing the press operation

The structure of a touch switch

The light touch switch is mainly composed of 5 component combinations, which can achieve various tactile sensations by changing the shape and material of the components.

There are two operating directions for touch switches

Compared to the installation surface of the circuit board, there are two types of pressing: pressing from the front direction and pressing from the side direction.

According to different applications, these two different types can be used to achieve flexible design. The following are usage cases of side operated switches.

Because the side operated type has multiple installation types, it is important to understand the characteristics of each type, which is helpful for selecting the correct switch.

The quality of touch switch purchase instructions will directly affect the use of the product, so we must understand it clearly before purchasing. Before purchasing, attention should be paid to its solderability, protection, conductivity and other electrical properties, as well as whether the service life and the positive and negative tolerances of the hand feel are within a reasonable range. External factors are also very important. Although we are not an appearance association, the appearance of a product can affect its quality. In order to reduce resistance, we will use silver plating on the pins. High quality products will use the silver plating process on the pins, and the process is also controlled. The silver plating thickness should be above 0.3um to effectively prevent pin oxidation.
