Frontmembranes The front membrane is the visual and tactile interface between your membrane keypad and the user. It can be labelled and surfacefinished using a number of different printing and embossing methods. The visual impression made is also of decisive importance for the appeal of your device! Various materials, including polyester and polycarbonate, combined with geometrical flexibility, colour and design, permit ergonomically rational flat membrane keypads for electronically controlled devices. Our high-quality front membranes conform to high tightness and robustness standards....

For tactile key delineation. Height: 0.6 - 0.8 mm* Cap embossing Cap embossing is a cap-shaped projection. This form of embossing is used for installation of LEDs, enabling levelling out of component height and intensification of the illumination effect. Raised embossing Raised embossing can be executed in various forms.

Membranes are embossed primarily to improve ease of use. Series of keys are made “feelable”, while the membrane effect of the embossing improves tactile feedback from the actuating elements. Embossing can, of course, also be used as a design element for emphasis of design membrane sectors. Height: 0.3 - 0.5 mm* Rim embossing Rim embossing is applied as a guide for the fingers. The surface level of the front membrane and key surface remain the same. DOME EMBOSSING Profiline embossing Dome embossing is possible in diameters ranging from 8 to 17 mm. This especially high embossing is the basis...

Printing methods Industrial screen printing forms the basis for the production of all types of membrane keypads. Previously unachieved flexibility in front membrane design. Our high-gloss technology is a special surface design treatment. SCREEN PRINTING Digital Printing HIGH-GLOSS TECHNOLOGY We work under cleanroom conditions using the latest, highly specialised equipment in the form of multiple production lines which print your design motifs onto the membrane flexibly and with no sacrifices in quality. Digital-printing technology is especially suitable for prototypes, short production...

For demanding applications, we create exclusive high-quality membrane keypads that incorporate the outstanding properties of surface-treated copper conductors. Membrane keypads with copper conductors High-quality copper-laminated membranes form the basis for a membrane keypad. These are silver- or, for extreme applications, gold-plated. The technology of copper-laminated switch wafers permits reliable SMD equipping with electronic components, followed by soldering. Silver migration can be greatly reduced or, in the case of gold-plated conductors, eliminated entirely. The Cu conductors...

This technology succeeds in providing outstanding data-entry operation for a large range of industrial requirements. Customised design for every keypad! Profiline membrane keypads Our premium keypads are equipped with Profiline technology. Excellent tactile feedback with “shortstroke feeling” and outstandingly good switching performance are the characteristics of our Profiline techno- logy. It is also linked to many degrees of freedom in key geometry, key size and design. This is all assured by means of an inlay consisting of a special plastic and positioned above the switching elements....

Illuminated membrane keypads Assists error-free operation in low-light conditions. Our illuminated membrane keypads make operation easier in low-light situations and thus assure reduction of user errors. LEDs are predominantly used for illumination of the display, and of operating and design elements. The lowest-cost configuration for signal generation is implemented using LEDs and LED windows. These can be executed with or without embossing. PROFILINE backlit The use of special LEDs and special treatment of the inlay provides homogenous illumination, with long service life naturally...

USB keypad Plug & Play – the membrane keypad for immediate operation using the USB port. We use printed electronics to integrate configurable keypad controllers into the membrane keypad. The ribbon cables needed can thus be narrower and can be connected directly to USB A sockets. Additional customer hardware for operation of conventional membrane keypads is thus no longer needed. ⁄⁄ Cost, space and time-savings ⁄⁄ Optimum for connection to PC or embedded system ⁄⁄ 188 functions thanks to three control levels (FN keys) ⁄⁄ 19 macros, mouse function, multimedia keys Plug & Play operation is on...
