The circuit of membrane switches can be flex and rigid. It depends on the customer end application and also related to the cost budget and other considerations. For example, life, resistance, connection type on the mainboard, etc. Usually if the membrane switches need assembled many LEDs, then we suggest to use FPC circuit, it can get more stable LED soldering quality. For the normal application the PET circuit is enough, which is more economical. In addition if the conductor pitch is 0.5mm, although we also can print it, but we still suggest to use FPC circuit. Because of that 0.5mm pitch is too small and it is easy to occur the short circuit problem.

Bitumer Elaston 2K is a two-component, liquid and flexible fiber-reinforced asphalt-rubber membrane. The high dry matter content mass allows the creation of a durable protective coating that effectively protecting building structures from moisture contained in the soil. Elaston 2K is a product that forms a flexible corrosion barrier with strong adhesion to the surface to which it is applied. Bitumer Elaston 2K can be used: •to isolate water leaks in covered areas wet areas such as bathrooms, kitchens, toilets, etc, •in external insulation of ground walls, basements and underground warehouses, etc, •along with reinforcement such as fiber mesh, non-woven polyester, etc. in cracked surfaces, •in insulation applications where strength is required-resistance to high water pressure, •on all horizontal and vertical surfaces.
