Trust in our expertise and let our quality convince you.

Proven classic

The single, classic silicone switch mat is still one of the most common switching elements in the electronics and automotive industries. As a central component, it triggers a direct switching function on the circuit board underneath and determines the feel, the optical and tactile impression and, via the integrated contact elements, the electrical behavior. In addition, the switch mat often takes on a sealing function on the circuit board. Its long mechanical service life with up to 10 million switching cycles makes it a long-lasting solution with a low maintenance risk.

Application of silicone keymats

Silicone keyboards are often used in devices and instruments where easy and reliable operation is required. They are used, for example, in remote controls, industrial controls and electronic measuring devices. In addition, silicone switch mats enable noiseless operation, which is advantageous in some areas of application such as medical technology or audio engineering.

Our silicone safety mats are used in almost all industries. Here you can see one small excerpt of our references:

Silicone Keypad Design

Silicone Keypad Design

Silicone safety mats offer an impressive range of design options that can be perfectly tailored to the specific requirements of different applications. They allow keys to be designed in different shapes and sizes, such as round, square, rectangular or custom shapes, and offer different sizes and arrangements for optimal ergonomics and usability.

They also allow a wide range of colors, including translucent and fluorescent options. Multi-colored buttons and backlights can also be integrated. The surface coatings and textures can be smooth or textured to provide enhanced haptic feedback.

Keys with epoxy coating for shiny surfaces

Thanks to the epoxy coating, the keys have a clear and shiny surface, which makes them more visually appealing and improves haptic feedback. The keys are also more resistant to abrasion and chemicals, which ensures a durable and resistant surface.

Plastic caps

Plastic caps for more flexibility

Keys with plastic caps offer a wide range of design options in terms of shape, color and texture. These caps allow you to design them in different colors and with different surface structures. In addition to a visual and haptic upgrade of the silicone safety mat, the easy interchangeability and customization is another advantage.

For illuminated versions, the keys are engraved using a laser. This precise method allows detailed symbols, labels and designs to be placed directly on the key surface. To ensure effective bundling of the light beam, light guides can also be integrated into the keys.

Illuminated silicone safety mats
Silicone keypads with multicolored keyboard lighting

We use an extremely precise 2K injection molding process to produce silicone keypads with multi-colored keyboard lighting. This process integrates a light channel into each individual key. and completely isolates the light channel from the rest of the transparent button. This ensures precise focusing of the light beam and enables multi-colored lighting.

Ideal for backlit keyboards

Highly transparent silicone keymat

Highly transparent silicone keypads are an interesting option, especially for backlit keyboards. To date, transparent silicone safety mats have tended to be milky, which leads to scattering losses from the light source. Highly transparent safety mats, on the other hand, offer one minimal light scattering, which means that the luminous flux almost completely reaches the surface. This makes them particularly interesting for brightly lit working environments or for use in daylight. In addition, the integration of light channels can be dispensed with, creating a closed surface.

In addition, such a silicone safety mat offers extensive protection of the underlying electronics from dust and moisture. The lighting can also be easily implemented into existing component components using status LEDs, so that fewer individual components are required. The material is also particularly suitable for switch mats with key caps made of plastic or metal, as well as paint finishes in the night design.

Phosphorescent silicone

It is also possible to make silicone safety mats from phosphorescent silicone. The silicone is charged by sunlight or artificial light sources and glowing in the darkDepending on the charge, several hours later. Such keyboards are used in the areas of security and building management technology, as well as in consumer products. By applying the appropriate paintwork in the night design, the labeling on the keys, for example, can also glow.

Silicone keyboard as front frame

Practical solution: silicone keyboards with a front frame module. The plastic front panel with integrated mounting sockets is coated with silicone. This creates an optimal connection between the individual components and one completely closed surface. The keyboard is protected against water and dust ingress and therefore enables quick, easy and thorough cleaning.

The individual keys can be painted, printed or lasered in a further processing step. In addition, special surface coatings with PU or epoxy coating are possible. The advantage of multi-component injection molding technology is that only one component has to be designed. This significantly reduces the investments and the effort for production and quality assurance.

As a central component, it triggers a direct switching function on the circuit board underneath. In applications with high reliability gold-plated contact surfaces on the circuit board is preferred. Screen printed carbon is widely used because of its cost effectiveness and strong chemical resistance.

The contact surface the circuit board should be in every direction be at least 0,5 mm larger as the contact surface of the keyboard. For rocker buttons and buttons with metal domes, please submit the circuit board contact circuit to us.

Development

construction and development

Thanks to our many years of expertise in the field of silicone safety mats, we offer you a comprehensive range full service at. Our engineers actively support you in the design and construction phase and in the selection of suitable materials.

Our product Designer design your silicone switch mat according to your wishes or revise the design or construction of an existing input solution. You have the choice whether you would like to use our development and construction services individually or as part of a more comprehensive support up to series delivery.

Our range of services includes sketching, conception, planning and preliminary construction, 3D/2D CAD design, realistic 3D renderings of product views and the creation of production documents such as technical drawings and parts lists. We can also produce prototypes using 3D printing or silicone casting.

For a first Services We need a technical drawing, an initial sketch or a sample as well as a requirement specification, technical specifications and information on equipment extras. Please also tell us the quantity required or the annual requirement.
We would also be happy to conclude a non-disclosure agreement / NDA with you.

Contact us under info@nh-technology.de. We look forward to your inquiry!
