Abstract
A control panel for displaying, monitoring and controlling conditions of a process plant, the control panel includes a graphic display, and permits quick and easy rearrangement and repositioning of control switches associated with the graphic display. The control switches are mounted behind a graphic display panel without extending through the display panel, and the control switches are actuated by the presence of an object such as an operator's finger at the outside of the display panel. The control switches may be magnetically secured in place, so as to permit ease of repositioning.
Claims12
A control panel for controlling conditions of a process or the like, and including a display panel with indicia displayed thereon, the combination therewith comprising:
- at least one trigger zone indicated on the display panel;
- and
- at least one control means positioned behind said display panel and not extending through the display PG,15 panel, said control means being selectably movable behind the display panel and positionable in an infinite number of locations relative to said display panel, each said control means including switch means sensitive to the presence of an object at said trigger zone of the display panel for creating a control signal in response to the presence of an object at said trigger zone.
A control system for controlling operating conditions of a process or the like, said control panel comprising:
- a display panel including a plurality of trigger zones indicated thereon;
- a backing panel mounted behind said display panel;
- a plurality of control means releaseably mounted against said backing panel adjacent the back side of said display panel, each said control means being movable about said backing panel and positionable in an infinite number of locations on said backing panel and not extending through the display panel;
- and
- each said control means comprising a switch means sensitive to the presence of an object at one of said trigger zones for creating a control signal in response to the presence of an object adjacent said trigger zone.
Control panel apparatus having an infinitely positionable control means, comprising:
- display panel means having a front side on which is displayed indicia corresponding to a control funtion, and having a back side;
- a backing panel which is mounted in assembly with said display panel in spaced apart relation to said back side thereof;
- at least one control means which is selectably mountable at any desired location on said backing panel;
- and
- said control means including activation means which is located adjacent and in unattached relation to said back side of said display panel in predetermined relation to said indicia on said front side, said control means being operative to change a control signal condition in response to the presence of a predetermined condition applied at said front side of said control panel at the location of said indicia.
A control panel for controlling conditions of a process or the like, comprising:
- a display panel with indicia displayed thereon;
- said indicia including at least one trigger zone indicated on the display panel;
- and
- at least one control means positioned behind said display panel in predetermined relation to said trigger zone on the display panel and not extending through the display panel, said control means including means positioned behind said display panel and sensitive to the presence of an object in front of the display panel at said trigger zone of the display panel for providing a control signal in response to the presence of the object at said trigger zone.
