What is an HMI?

HMI, or Human Machine Interface, is the user interface of a machine that provides a graphics-based visualization of the controls and system monitoring on a piece of equipment.

There are a lot of terms used in our industry for HMI products including membrane switches, keypads, rubber keypads, keyboards, and control panels for example.

Traditionally membrane switches, rubber keypads, and touchscreens are examples of the part of the human machine interface which we can be seen and touched. Today, the key to developing the most reliable and effective HMI solutions involve combining not only those elements, but additional components like displays, LED’s, meters, power supplies, wire harnesses and many other complex items.
