A membrane switch is a printed electronic circuit that uses pressure to open and close a circuit. It is usually printed on PET with a conductive ink that includes silver and a conductive graphite layer to stop deterioration by corrosion.
The visible top layer is the graphic overlay and the printed circuit is underneath on another layer.
These switches are used on equipment to pass commands from users to electronic devices. Your computer keyboard or microwave oven will probably have a membrane switch to control its operation..
The main benefits of membrane switches are the ease of cleaning and sterilisation (particularly in health applications), the ability to seal out dirt and moisture and their low profile.
We currently specialise in the low to medium volume manufacture of flexible and rigid membrane switch panels.
The membranes offer such features as:
Our membrane switch panels are produced almost exclusively from polyester based materials offering excellent environmental performance under the most exacting conditions. Tactile response can be provided by stainless steel domes or thermally formed polyester "polydomes". Environmental sealing and electrical terminations can be provided to suit your enclosure and electronics.
We can help you with all types of membrane switches: flat, with sensitive touch guide, tactile effects, with or without female connectors. We can also supply switches mounted on plastic or metal panels.
We stock a huge range of standard printing colours or Pantone & special matches are available.
