JRPanel is a manufacturer of customized products. Generally speaking, membrane switches are customized things. They are not available in stock, and can be sold directly. Membrane switches need customization. Customers have different needs for membrane switches, which leads to different design, size, material or function of products. Sometimes special materials are needed to be custom-made. Therefore, JRPanel usually does not produce in advance and store a large amount of membrane switches. Otherwise, storing too many things will lead to additional costs. In addition, customer needs may change at any time. After we make an agreement on the design, production begins.
