The membranes offer such features as: Tactile and non-tactile switches Secret-till-lit legends and icons Tinted Filter display windows Key and Feature embossing Interchangeable legends Die cut apertures Selective UV cured textures for enhanced chemical resistance Water clear or anti glare LCD display windows RFI/ESD shields using both silver conductive ink and ITO sputtering techniques.

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.

• Switches and circuits are printed with a high silver content conductive ink onto 0.125mm polyester.
• Connections with female connector fixed on the flat cable type terminal, or connection by insertion of the flat cable into a female connector mounted on the card to be connected.
• Design is protected by the front panel, generally about 0.25 or 0.175mm thick.
• Practically unlimited shape possibilities.
• Adhesive film on reverse for quick mounting.
• Coloured or non-coloured transparent areas for the display system or LEDS to preserve the sealing.
• Circuit resistance according to the circuit length and the track width: generally lower than 200 ohms.
• Operating voltage generally lower than 24 V - maximum: 50 V.
• Normal operating current between 1 and 5 mA - maximum: 30 mA.
• Maximal contact bounce : 5 ms.

	Print Colours
We stock a huge range of standard printing colours or    & Special matches are available

• Flat switches: 0.15mm - 0.20mm.
• Tactile switches: 0.50mm - 0.90mm according to the embossing size.
• Contact during the pressure time.
• Operating force of 1 t 3 N proportional to the switch dimension and the switches type (flat or with tactile effect).
• Dustproof and waterproof.
• Operating temperature between -25C and + 65C.

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.
