Abstract
A control element for an electric control device is disclosed that includes a freely programmable symbolic system, whereby the symbols are projected into a side of the control element that is facing away from the operator by a controllable display unit and an illuminating device arranged in front thereof, or by a controllable display unit and an optics, or by a controllable display unit and a light guide, and whereby the symbols are made visible by a transmissive layer on the side of the control element that faces the operator, whereby alternating symbols are generated in the display unit.
Claims6
A control element according for an electric control device comprising:
- a freely programmable symbolic system in which symbols are projected into a side of the control element that is facing away from the operator by a controllable display unit and an illuminating device arranged in front of the display unit, or by a controllable display unit and optics, or by a controllable display unit and a light guide, and the symbols are made visible by way of a transmissive layer in the control element on the side facing the operator, wherein alternating symbols are generated in the display unit.
A method for generating a freely programmable symbolic system on a control element of an electric control device, the method comprising the steps of:
- projecting symbols are projected into an interior face of the control element by an illuminating device and a controllable display unit, or by a controllable display unit and optics, or by a controllable display unit and a light guide;
- transmitting the generated symbols via a transmissive layer towards the control element to a surface facing the user;
- and
- generating animated symbols are on the surface of the control element by symbols, which are alternatingly generated in the display unit, on the side of the control element that faces the user.
