What are the demonstrations of the internal structure operation of the touch switch

When touching the switch, lightly press the switch button to turn on the switch, and the switch will be disconnected when the hand is released. The internal structure of the switch is realized by the force and bounce of the metal shrapnel.

Touch switches are widely used in household appliances, such as audio and video products, digital products, remote controls, communication supplies, household appliances, security products, toys, computers, because of their small touch, obvious touch, clear hand, complete height standards, etc. Supplies, fitness equipment, medical equipment, banknote pens, laser pointer keys, etc.

Since the function of the touch switch is to touch the contacts and the shrapnel for touch conduction, the larger the contact, the better the contact surface. The contact surface is determined by the structure. Shopping malls have three structures, the order of their advantages and disadvantages are: large bubble (crater type), "O-shaped tactile", "2 contact" time slot type, and flat bubble type "1 contact". The quantity of life and feeling is the cooperative resolution of the stroke of the touch switch and the shrapnel. The shorter the stroke, the lighter the life, the longer the stroke, the longer the stroke. On the contrary, in the case of fixed shrapnel technology, the first step is to determine the shrapnel The lifespan of the switch; in addition, the key factor in the life of the shrapnel is still the stamping technology.

However, the touch switch also has its shortcomings. Frequent pressing will fatigue the metal shrapnel, lose its elasticity and fail. Therefore, most of today's electronic buttons directly use conductive rubber or pot switch hardware shrapnel to replace them, such as computer keyboards and remote controls. As far as the life span of the entire product is concerned, a good touch switch is also very important.

Such as computer keyboard, remote control, etc. If it is a residual touch switch, frequent pressing will fatigue, lose elasticity and fail the shrapnel. Therefore, the choice of touch switch is very important. The main factors that affect the reliability, solderability, reliability, service life, feel, production process and installation scale of touch switches are touch switches.

After all, it is the assembly skills that affect the quality, which depends on the management ability of the production company, the quality meaning of the employees and the quality assurance ability, etc. In order to ensure the difference in shipping capacity, the final commercial quality and quantity must be different. Nowadays, there are manual and machine assembly methods in shopping malls. Because the degree of automation can be further improved, each method has its advantages and disadvantages: machine assembly costs are low, but the enterprise quality is low, so each method has its own advantages. Disadvantages: machine assembly costs are low, but business quality is low. The cost of manual assembly is high, but the quality is also high.
