Knitter-switch offers 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 economic, small size, multi-layered, moisture sealed, self adhesive mounting switching systems 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 combines the most popular features of both membrane and rubber keypads into its dual technology keypads. This form of switching can be used economically for 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, thin and have the facility for backlighting.

With 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 simple to connect via a flexi-tail PCB terminated with the customer’s choice of male or female connector.

Typical applications for knitter-switch dual technology keypads include security access systems, environmental controls, industrial and factory equipment, medical systems and home automation. The company supplies membrane switches and rubber keypads to OEM’s worldwide.
