In the meantime silicone rubber keypads are one of the most widely used switch technology in the electronic industry. You find it in all applications like industry, automotive, measurement, medicine, military, agriculture, consumer products and many other applications. Due to their high reliability, long lifetime, good tactile response and very robust characteristic.
Silicone rubber keypads are very flexible in their design, tactile haptic, colours, different surface coatings like Epoxy, PU, plastic/metal caps which can increase the abrasion resistance, the UV resistance and chemical resistance. |
The rubber can be manufactured in all colours, including metallic-effects. So each key can have their own colour.
Stroke and operating force can be adjusted at a wide range depending on customer’s requirements. Multiple switching-functions are also possible like rocker switches.
In combination with customer housing a protection class up to IP68 can be realized.
Due to translucent silicone in combination with laser etching you can backlight the keys one by one or as a complete design.
There existing various solutions for the electrical contacts of the silicone keypads like silver ink (low cost), carbon pills, metal domes or only silicone. |
