About DEWO

Dongguan DEWO Electronic Technology Co., Ltd was established in 2011. With several years’ experience of research and developing of switch making we became a professional switch manufacturer.

The biggest technical feature of DEWO micro switch manufacturers in micro switch design is to prevent loss and prolong its service life. Micro Switch loss can be divided into wear and fatigue, micro switch wear means contact surface wear or material loss; micro Switch fatigue refers to the generation of fatigue cracks or the reduction of fatigue life of metal and other materials. Increasing the strength of the surface of the micro-motion contact element is the main way to slow down the loss. Through various surface treatments, such as physics (hardening technology that changes the surface microstructure such as laser and ion implantation), Chemistry (surface hardening technology such as carburizing and nitriding), machinery (shot blasting, rolling, etc. to increase the residual stress on the surface) process methods make the surface of the material obtain special components, structure and performance, so as to improve the wear resistance and fatigue resistance of the micro switch. In addition, there are also ways to strengthen the electrical ability of metal reeds and contacts of micro switches, such as replacing metal materials such as silver and alloy.

The change of micro switch structure design can also reduce the loss. Such as changing the geometric structure, clamping mode and contact size inside the micro switch, and also changing the pressure distribution and contact mode at the contact surface, the anti-damage performance of the micro switch can be improved to varying degrees. Another effective measure to slow down the micro-motion loss is that it can reduce the friction coefficient of the micro-motion switch by increasing the lubricating medium.
