The market demand for touch switches was highest in the 1980s to early 1990s. In recent years, the demand has been maintained at around 50 million units. This product has always been considered to be replaceable with button switches, toggle switches, etc., so it is natural that market demand is showing a downward trend. Among them, small and ultra small touch switches have always been favored. Large button switches with high current have matching applications in some special occasions.

Due to breakthroughs and upgrades in technical materials, the waterproof, safety, and reliability of the touch switch have greatly improved, and the product cost has continuously decreased. The market demand for the product continues to be optimistic. Due to convenient assembly and continuous expansion of application fields, it has replaced many switches. The installation form is mainly circuit board mounting. The largest market in the application field is vehicle mounted instruments, CNC machine tools, washing machines, keyboards, mobile phones, detection instruments, etc.

At present, most enterprises are foreign-invested, with sales scales ranging from 20 million to 100 million yuan. This type of enterprise is mainly concentrated in the Pearl River Delta and Yangtze River Delta regions, with an annual growth rate of over . The huge domestic demand has led to a continuous increase in its import volume, and foreign-funded enterprises are increasing their investment and production capacity, with a trend of becoming longer and larger.

According to analysis, in the past two years, the highest demand in China has been for touch switches, with a total demand exceeding one billion or even more; The film switch has the largest growth rate, with a growth rate of over ; The demand for button type switches (including button type power switches, microswitches, remote controls, mice, and keyboards) ranks first in Asia. In 2005, the total demand for various major switches in China exceeded 8.827 billion units, and it is expected to reach 9.88 billion units this year.

The types of light touch switches include standard type, sealed type, SMD type, waterproof type, swing rod type, long type, vertical type, semi circular array thin type, and illuminated type (red, yellow, green); The appearance is square, rectangular, circular, flat, convex, vertical, and long-life. The main installation forms include plug-in welding, embedded pin type, surface mount, etc. Its advantages are suitable for high-density surface mounting, some can be cleaned after welding, and the sealed type can be waterproof and dustproof, making it very suitable for harsh environments. The circuit design is simple, and the product life ranges from 100000 to 10 million times.

The SMD touch switch is a product with the fastest growing market demand and the widest range of applications in the past decade. During the development of four major products, including color televisions, video recorders, combination audio systems, and VCDs, touch switches have also made significant progress.
