Input systems

Individual and versatile

Input systems, also known as HMI (Human Machine Interface), connect the user with technical devices and machines. In most cases, the input system is taken for granted and it is often forgotten that the HMI is used to assess the usability of an entire device.

Hoffmann + Krippner develops and manufactures customized operating solutions from the initial concept through to series production for a wide range of industries.

Input technologies
at a glance

Depending on the application, different technologies are used: from the classic membrane switch to modern capacitive buttons, display buttons and touch systems through to a complete HMI solution. The right technology depends on requirements such as operating comfort, installation space, environmental conditions, service life and the desired functionality. Hybrid input systems that combine multiple technologies in one system are also possible.
