Abstract
A control panel for an elevator has at least one pressure-sensitive action field in order to trigger an action by pressing. The control panel has a layered construction with a top plate, a base plate and a piezo element. An opening is provided in the top plate to define the action field. The piezo element is seated in the region of the opening between the top plate and the base plate so that by pressing in the region of the action field a force can be exerted on the piezo element and the piezo element delivers an electrical output signal to an electronic circuit. The electronic circuit provides an electrical acknowledgement signal in order to produce a change recognizable at the control panel as an acknowledgement.
Claims14
A control panel for an elevator, wherein the control panel has at least one pressure-sensitive action field in order to trigger an action by pressing, comprising:
- a top plate having an opening for the action field;
- a base plate;
- a piezo element positioned adjacent said opening and between said top plate and said base plate whereby pressing in the action field exerts a force on said piezo element and said piezo element generates an electrical output signal on lines adapted to be connected to a control circuit;
- and
- acknowledgement means responsive to an electrical acknowledgement signal from the control circuit for producing a change recognizable at the control panel as an acknowledgement of the output signal.
An elevator with a control panel arranged in or at an elevator car of the elevator, the control panel comprising:
- a top plate having an opening for an action field;
- a base plate;
- a piezo element positioned adjacent said opening and between said top plate and said base plate whereby pressing in said action field exerts a force on said piezo element and said piezo element generates an electrical output signal on lines connected to said piezo element;
- and
- acknowledgement means responsive to an electrical acknowledgement signal for producing a change recognizable at the control panel as an acknowledgement of said output signal.
