The use of silicone rubber keypads is popular in HMI devices.

They are characterized by a long lifespan, reliable operation, and high UV and IP protection can be achieved.

Any 3D shape, size and color combination can be created.

The back of the buttons can have a conductive (carbon) layer for direct connection to the contact formed on the PCB, but can also be combined well with printed electronics, for example.

Its production is very affordable for medium and large series.
