Analyze the size and development of four-foot tact switch package
The four-foot tact switch is a product switch that is more common in electronic switches and electronic components. It is also a very popular switch. The four-foot tact switch is also divided into a four-foot patch tact switch, a four-legged waterproof tact switch, and a four-legged light tact switch. Each of the different switches has its own standard model. Unlike the same standard model, the four-foot tact switch package size is different, but the general considerations are the same.
The four-foot tact switch has a variety of package sizes. The more common and commonly used standards are 6*6 tact switches, 12*12, 4*4, 2*4, 3*6, 3*4, etc. Various. The most common package includes SMT chip package, DIP plug-in package and bulk manual plug-in. The basic information is as follows:
One, four-foot tact switch welding and cleaning process should pay attention
1. Because the four-foot tact switch is small in size and light in weight, the temperature of the wave soldering is controlled at 130 ° C, and the welding time is about 2 seconds.
2. The welding time is about 10 seconds and the temperature is controlled at 200 °C.
Second, four-foot tact switch product standard:
1. The rated current that the switch does not switch frequently: maximum 400mA3. The rated current that the switch often switches: maximum 150mA4. Insulation resistance, minimum 100m. Four-foot tact switch supply
2. Rated voltage: 24V maximum.
Three, four-foot tact switch mechanical properties:
1, the operating temperature: -20 ° C ~ +70 ° C, operating force: 100gf-350gf3.
2, the number of electrical life: 10,000 times.
Due to its small size, multi-gear position, and good driving force, it has been widely used in many fields such as household appliances. With the continuous improvement of people's living standards, the upgrading of these household appliances is getting faster and faster, and the number of them needs to be larger and larger. This is also the biggest potential direction for us to be optimistic about its development prospects.
