What is the requirement when using the light touch switch on the side of the mobile phone? Specific details we will give you a detailed introduction below.
Now it is widely used in mobile phones, digital cameras and other electronic industries. Inside is a tiny metal shrapnel switch. The touch switch used by mobile phones is smaller than other switches. The touch switch on the mobile phone will feel crisp when pressed. Side-touch switches manufactured by Zhengmao Electronics are also widely used in the mobile phone industry.
On the side of the mobile phone, press the light touch switch requirement:
1. The size of the touch switch on the mobile phone side is small. It belongs to the patch touch switch and can be reflow soldered. For tape packaging, in order to improve the installation density of components on PCB, it can be installed on high-density small mobile devices.
2. Operating power: 100g, 130g, 160g. Silicone keys for mobile phones require touch, life and strength. But these three are mutually reinforcing negative factors. If one point rises, the other two points weaken.
3. High shrapnel requirements and crisp handle. Frequent extrusion can cause metal fragments to lose elasticity in fatigue and failure. So now most of the buttons are directly replaced by conductive rubber or pot switch hardware shrapnel, such as computer keyboard, remote control, etc.
