The quality of the touch switch 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.

2. The light touch switch is composed of a plastic base, hardware terminals, hardware springs, hardware cover plates, plastic handle, springs, and PI film.

3. The touch switch belongs to a type of passive component and cannot be used alone. It can only be combined with the active component to form a control system, and its function can be fully realized. The working principle of a normally open light touch switch: Pressing the switch button during operation can make the switch turn on. When the button is released, the switch is both turned off, and its internal structure is achieved by the force exerted by metal springs. The principle of a normally closed light touch switch: Pressing the switch button during operation can disconnect the switch, and when the hand is released, the switch is already on. Based on the above two principles, it can be seen that there are two methods for this switch, which can be selected based on our own product performance requirements. Based on the analysis of its working principle, it can be seen that this product also has defects. It relies on the force exerted by metal shrapnel to make and break, so once the metal shrapnel loses its elasticity, the product cannot be used. Therefore, this product has a lifespan limit.

4. Explanation of touch switches, also known as button switches, English names: TOUCH SWITCH, TCAT SWITCH. It is generally called by its external dimensions, such as 6 * 6 * 5, which refers to its length, width, and height. It belongs to a type of electronic switch, which is different from wall switches in household use. The difference lies in the different application fields and their own structural functions, so it is called an electronic switch. It is divided into: push type and surface mount touch type. The difference between the two lies in their volume and welding form. The push type is mainly a plug-in light touch switch with a larger volume; The surface mounted touch control type is mainly the ultra-thin type of patch light touch switch. The light touch switch is used to apply pressure to the shrapnel by pressing the handle to ensure that the contact stroke between the shrapnel and the shot point is conductive. Therefore, it can be divided into three forms: one is the normally open type, one is the normally closed type, and the other is the dual action type. There are also three types of switch positions: one is a two pin switch, a three pin switch, a four pin switch, and a five pin switch.

5. According to the working principle of light touch switch products, we can use it for audio volume control, power keys of various electronic products, function selection of various products, remote control buttons, Computer keyboard and other electronic products, which are indispensable in our daily life. It has such a wide range of uses and a wide range of usage environments. A single product performance can no longer meet the market demand, and extended products have also been developed. Currently, the market includes products such as ultra-thin, waterproof, dustproof, with bracket, sink plate, with lamp, long service life, ultra small, light force, gravity, and so on. The variety of products is becoming increasingly diverse, and the demand for our market is also increasingly matching. It can be seen that the emergence of touch switches is indispensable for our development.

6. Touch switch products also need to be well used in order to effectively exert their effectiveness. Before use, it is necessary to confirm the production conditions, and different welding methods should use different pins and temperature resistant materials. Due to different conditions, the ways of pin pins are also different, and pins can be divided into plug-in type and chip type. After production, the performance of the switch must be tested, whether the switch is normally on or off, whether the hand feeling changes, whether the product resistance is normal, whether the product appearance is normal, whether the switch pin is in the welding position, etc., and reasonable production SOP must be formulated for all unused production processes.
