Dual Technology Keypads add options for Designers

Knitter-switch can now offer designers a new form of man-machine interface by combining the key features of membrane and rubber keypads into a single, highly customisable, dual technology keypad.

Membrane keypads offer very economic, small size, multi-layered, moisture sealed, self adhesive mounting switching solutions which may be printed with graphics to match the end product. Rubber keypads have the advantages of better tactile “feel”, greater choice of form (shape and size of button or actuator), the ability to be backlit and are lower cost than membrane keypads.

Knitter-switch is one of the few manufacturers to be able to combine the most popular features of both membrane and rubber keypads into their new dual technology keypads. This new form of switching can be used economically for just a single switch through to a multi-key keypad. The surface of the final keypad may be flat or contoured and will sit on the end equipment like a label, minimising assembly time and cost. Knitter-switch dual technology keypads are space-saving, very thin and have the facility for backlighting. With excellent tactile response for positive switching the individual keys may be domed and if required polyurethane coated for a robust finish which also protects any printed legends against wear. The complete keypad can be sealed to IP65 and is very simple to connect via a flexi-tail PCB terminated with the customer’s choice of male or female connector.

Terry Moss, General Manager for the UK and Nordic Regions comments. ”We have a number of customers who have been looking for the size and cost benefits of membrane keypads but who also require greater tactile response and illumination. Our new dual technology keypads now offer all these features in a simple to fix, robust, cost effective keypad which may be completely customised to fit the application.”
