What are the types of light touch switches? What is the amount of use, we will give you a detailed introduction below.
Touch switch is an electronic switch, which can be switched on by pressing the switch button lightly. When the switch is loosened, the switch is disconnected, and its internal structure is realized by the force and elasticity of the metal elastomer.
The light touch switch has the characteristics of small size, ultra-thin, very small press force (minimum N can reach 0.98) and light weight. Types include standard type, sealed type, SMD type, waterproof type, pendulum type, long type, vertical type, semi-circular array thin type, etc. The contacts are silver-plated and gold-plated. Installation forms mainly include insertion welding, insertion pin, surface mounting and so on. Dimensions are 4.5 x 4.5 mm, 6 x 3.5 mm, 6 x 6 mm, 6.6 x 6.6 mm, 8 x 8 mm, 10 x 10 mm, 12 x 12 mm, etc. Advantages are suitable for high-density surface mounting, some can be cleaned after welding, sealing type can be dust-proof, the most suitable for harsh environment selection, simple circuit design. The life of products ranges from 100,000 to 10,000,000 times. The products have been in series.
Light touch switch has become one of the most demanded switch categories in China. Portable consumer digital provides 3 kwuv transformer manufacturer electronic products and instrumentation is the most widely used field of light touch switch. Because of its small size and light weight, it has been widely used in household appliances, such as video and audio products, digital products, remote controllers, communication products, household appliances, security products, automatic spray guns, toys, computer products, fitness equipment, medical equipment, money checking pen, laser pen keys and so on. But touch switch has its shortcomings. Frequent pressing will make the metal shrapnel lose elasticity and become ineffective due to fatigue. So now most of the electrical buttons are directly replaced by conductive rubber or pot switch hardware bullets, such as computer keyboard, remote control and so on.
For example, a color TV needs 6, and a set of combined audio needs about 20. Nowadays, the application scope of touch switch is still expanding. The main fields are video electronic products, household appliances, medical electronic products, car audio, portable electronic products, automatic control systems, testing and measuring instruments, etc. The market supporting demand continues to be optimistic, and the competition between businesses is becoming more and more fierce, mainly in the production of specialization, automation is becoming stronger and stronger, production has increasingly concentrated in a few powerful, large-scale enterprises. With prices falling all the way, profit margins are getting smaller and smaller, and some smaller enterprises have the idea of withdrawing from competition.
