The rapid growth in market demand for tact switches

September 24, 2021

The tact switch is a product with the fastest growth in market demand and the widest application in the past ten years.During the development of the four major products of color TV, video recorder, audio system, and VCD, the tact switch has also gained a larger share. develop.

Tact switch classification

The types of tact switches are standard type, sealed type, SMD type, waterproof type, pendulum type, long type, vertical type, semi-circular array thin type, etc., with light type (red, yellow, green), and the appearance is square, Rectangular type, round type, flat type, convex type, vertical type, long-life type, the main installation forms are plug-in welding type, embedded pin type, surface mount, etc.The advantage of light touch switch is that it is suitable for high-density surfaces Mounting, some can be cleaned after soldering, sealed type can be waterproof and dustproof, very suitable for harsh environments, simple circuit design, product life ranging from 100,000 to 10 million times.

Application of light touch switch

At present, light-tact switches with light are widely used in portable consumer digital electronic products, household appliances and office supplies, instrumentation and other fields, such as a set of color TV sets of 6 applications, and a set of combined audio applications about 20 sets. Nowadays, the scope of application is still expanding, and the main areas are medical electronic products, car audio, automatic control systems, testing and measuring equipment, automobile transportation and so on.
The tact switch market continues to be optimistic, and the competition is becoming more and more fierce. It is mainly manifested in the production specialization and automation. The output has become more and more concentrated in a few powerful and large-scale enterprises, plus DC power supplies. The price of sockets has been falling all the way, and the profit margin is getting smaller and smaller. The situation of one or two hundred companies producing more than a decade ago or more than 20 years ago has been changed. Production is basically concentrated in more than a dozen representative foreign-funded companies and mold technologies. In the hands of joint-stock and private enterprises with strength and advanced processing equipment. Tact switches have now become the most demanded switch category in China, and they are also one of the most exported and imported products.
