A membrane switch is a front panel device used with a normally open circuit. They are called membrane switches because they consist of visual and inner layers printed on polyester.
The ultimate purpose of a membrane switch is to act as an interface between man and machine by enabling an operator to communicate with an equipment, tool or machine part.
The layered nature of membrane switches provides great freedom for engineers to design and implement a very precise customer experience. Because of this flexibility, these user interfaces are used in a wide variety of industries including medicine, consumer electronics, military / Department of Defense and aerospace.
There are many parameters to consider in membrane switch design, including graphics, coatings, adhesives, and use cases.
The coating is the top layer of a membrane switch and is the interface between the user and the machine. Two of the most important issues to consider in graphic coatings are durability and environmental concerns. Graphic coatings can be made from polycarbonate, polyester or acrylic and the material you choose will depend on the desired level of durability and whether it needs to be protected from scratches, chemical abrasions, extreme temperatures or operation. For good tactile feedback on the keys, choose a coating thickness between .006 and .010. This series will offer the durability to meet your requirements, with the sensitivity to provide a quality tactile effect.
Adhesive tapes are important in membrane switches; membrane combines with graphic overlay and connects the entire assembly to your product. There are many differences in adhesives; Choosing the appropriate adhesive for the application requires consideration of environmental, surface, appearance and other performance requirements.
It can be embossed in multi-level shapes depending on the shape and size. Buttons can also be embossed for added tactile feel.
Circuits can be printed using silver conductive ink or printed circuit boards (PCBs).
Membrane switches can be designed with almost any SMT component, resistors, light sensors, and any low surface mount components if required.
Appropriate shielding is required to meet ESD, EMI, or RFI requirements.
Membrane switches can be designed to be touch or non-tactile to meet desired product requirements.
Membrane switches must be reliable for years when used daily or even hourly. This requires active and purposeful design for lifetime operation.
By working with experienced membrane switch designers and manufacturers, engineers can leverage this supply chain expertise to optimize components to meet this requirement.
By using polyester materials for the top layer graphic coating, you can maximize environmental durability and chemical resistance. However, the dimensional stability of polyester also makes it difficult to shape, so visual embellishments such as raised buttons and embossing can be difficult to apply.
Due to the many harsh environment applications, membrane switches must be able to withstand the environment they are in. Dirt, dust, moisture and chemical cleaners are all damaging.
Polyester is better, so many manufacturers prefer blended materials. Polyester can help engineers address visual and environmental requirements of various sizes.
Depending on the application, membrane switches can be exposed to adverse weather conditions. In these situations, protecting and protecting internal components from moisture becomes essential.
Various options are available (3M HV tapes, custom design solid gaskets, etc.) that allow engineers to design interface assemblies that meet different environmental standards. For example, membrane switches can be developed to meet IP sealing standards.
