The light touch switch belongs to the functional switch. The light touch switch can be turned on by pressing the switch button lightly when it is used. When it is loosened, the switch can be disconnected. Its internal structure is realized by the force and elasticity of metal shrapnel. With the rapid development of power electronics technology, power electronic equipment and people's work and life can be realized. The living relationship is getting closer and closer, and the electronic equipments are inseparable from reliable power supply. Switching power supply is a kind of power supply which uses modern power electronics technology to control the time ratio of switching transistor on and off and maintain stable output voltage. Switching power supply is generally composed of pulse width modulation (PWM) control IC and MOSFET.
1. For the pin base material, the pin base material of the light touch switch is brass or phosphorus copper. In order to reduce the contact resistance, the pin is basically silver plated. The SO2 gas in the silver meets the air will oxidize, which directly affects the solderability and contact resistance of the switch. Therefore, the high quality light touch switch should first be silver plated on the pin base material and silver plating process. The control is in place.
2. The key factor affecting the reliability of conduction is the structure of contact point. Because the function of touch switch is contact point and shrapnel conduction, the bigger the contact surface is, the better the contact surface is. The contact surface is determined by the structure. There are three kinds of structures in the market. The order of advantages and disadvantages is as follows: Bubble "O-type contact" and grooved "2-point contact". Touch and Flat Bubble Type "One Point Contact"
3. Life and hand feel are determined by the stroke of the flip-flop switch and the cooperation of the shrapnel. The shorter the stroke, the lighter the sound, the longer the travel, on the contrary, in the case of fixed shrapnel technology, the life of the flip-flop switch is mainly determined by the stroke or sound. In addition, the key factor determining the life of the shrapnel is stamping technology, so in the case of fixed shrapnel technology, the life of the flip-flop switch In the case of technological upgrading, whether the requirements for imported materials are further reduced, such as 160gf shrapnel life in the market is mainly four kinds: 50,000 times, 100,000 times, more than 200,000 times.
