Polyester Dome:

An exclusive Tortai manufacturing process produces the industry highest quality polytactile dome in the graphic layer. This provides switch users with keypad that has strong, uniform tactile feel and a choice of standard or high temperature performance at an affordable price. And the combination of in-house manufacturing and design means shorter lead times.

Features and Benefits

• Dual Purpose - the dome helps the user identify the key location and provides tactile feedback.
• Consistency - thanks to our in house designed and manufactured equipment, we can produce a consistent dome from keypad to keypad and order to order.
• Withstands High Temperature - because we use a proprietary forming process developed in-house, the polyester is molecularly reshaped into the geometry of the dome, thus the memory of the plastic sheet is in the geometry of the dome.
• Crisp Tactile Feel - due to the process and the dome geometries developed, we can ensure a firm nap throughout the specified life of the switch.
• Reliability - tested beyond 2 million actuations.
• Design Flexibility - We can custom design our dome to meet any of our customers requirements . And additional domes on a given part can be added with little or no increase to the piece price.
