Description

User-friendly, flexible membrane switch keyboards that are long-lasting, reliable and cost-effective. The Tortai process produces a thermoformed polyester foil with "elastic" spring zones enabling extended key travel. Advantages over conventional membrane and metal dome based keyboards: Significantly reduced contact bounce Long key travel, 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. Tortai retains essentially the same ergonomic performance as standard mechanical push buttons, but is also: Dust-tight Water-tight Chemically resistant Circuit layers are printed on polyester substrates with special silver, carbon and insulation inks, with additional protection against oxidation provided by over-printing with carbon. Key benefits of Tortai technology: Long-lasting: in excess of 1 million actuations Long travel: up to 2mm Low contact bounce of <2ms Tactile response: hard and soft variation Stable operation in temperatures from **0 deg C to **5 deg C Dust, water, scratch and chemical resistant Aesthetically pleasing, slim-line, ergonomic design Cost-effective
