Production and assembly steps of membrane switches

Membrane switch is a new type of high-tech switch, has been widely used in various fields, including life based equipment. An important component of the membrane switch is the membrane panel, which includes many other steps in addition to this one. The steps and processes of membrane switch production and assembly include various aspects such as sticking tail line, punching tail line, making interlayer and veneer adhesive. We will make a detailed analysis of each small detail below.

Basic structure and working principle of membrane switch

Membrane switch is a kind of multi-layer structure (plane) type (non-locking) key switch composed of a certain elastic insulating material layer, which integrates the functions of keys, indicating components, instrument panels, etc. The action of the membrane switch is only realized by the vertical movement of the elastic membrane. Although the elastic membrane has undergone millions of peristalsis, the amplitude of peristalsis is very small, only 0.1-0.3MM. In addition, the material selection is reasonable, so the membrane material can withstand a large life of more than one million times without deformation, which all determine the durability of the membrane switch.
