User-friendly, flexible membrane switch keyboards that are long-lasting (>6 million actuations), reliable and cost-effective.
The Clicktouch process produces a thermoformed polyester foil with “elastic” spring zones enabling extended key travel. Circuit layers are printed on polyester substrates with special silver, carbon and insulation links, with additional protection against oxidation provided by over-printing with carbon.
Advantages over conventional membrane and metal dome based keyboards:
•Significantly reduced contact bounce (<2 ms)
•Long key travel (up to 2 mm) providing improved tactile feedback (even when operated by someone wearing gloves, a clear click can be sensed)
•No metal parts, resulting in a longer switch life and greater reliability.
Clicktouch retains essentially the same ergonomic performance as standard mechanical push buttons, but is also:
•Dust-tight
•Water-tight
•Chemically resistant
