Abstract

An exemplary embodiment of a keypad for building automation may comprise a sensing layer operable to detect user input. The sensing surface configured with a plurality of switching fields assigned to different automation functions. A printed label is layered over the sensing surface for identifying the different automation functions to a user. Control circuitry is operatively associated with the sensing surface. The control circuitry receives user input corresponding to at least one of the switching fields on the sensing surface, and the control circuitry generates a signal for executing the automation function assigned to the switching field at an automation device.
