Base assemblies for Knob on Display devices and related systems, methods, and devices

A knob on display system comprising:

• a touch screen device comprising a touch sensor and a touch screen;
• and
• a knob on display device comprising:
• a conductive cap, the conductive cap at a top of the knob on display device;
• a dome switch, the dome switch under the conductive cap, the dome switch electrically connected to a touch surface of the conductive cap;
• a printed circuit including conductive pads, the conductive pads including one or more dome switch pads, the dome switch mounted on the one or more dome switch pads;
• a base assembly, the base assembly at a bottom of the knob on display device;
• an inner housing, the inner housing between the conductive cap and the base assembly, the inner housing enabled to rotate about a post within the base assembly;
• at least one electrode comprising an electrically conductive material, the at least one electrode including an electrode electrically connected to the touch surface of the conductive cap via the dome switch and the one or more dome switch pads, the electrode mechanically coupled to the inner housing to rotate with the inner housing;
• and
• a bottom side of the base assembly secured to the touch screen of the touch screen device, so that the electrode is positioned in engagement proximity to the touch screen through the base assembly.

A method of assembling a knob on display system, the method comprising:

• applying an adhesive to a bottom side of a base assembly of a knob on display device, the knob on display device comprising a conductive cap, a dome switch, a printed circuit including conductive pads, a base assembly, and one or more electrodes, the conductive cap at the top of the knob on display device, the dome switch under the conductive cap and electrically connected to a touch surface of the conductive cap, the conductive pads including one or more dome switch pads to mount the dome switch thereto, the base assembly at a bottom of the knob on display device, an inner housing between the conductive cap and the base assembly, the inner housing enabled to rotate about a post extending from the base assembly, the one or more electrodes comprising an electrically conductive material, the one or more electrodes including an electrode electrically connected to the touch surface of the conductive cap via the dome switch and the one or more dome switch pads, the one or more electrodes mechanically coupled to the inner housing to rotate with the inner housing;
• and
• securing the knob on display device to a touch screen of a touch screen device with the adhesive on the bottom side of the base assembly, to thereby position the one or more electrodes in engagement proximity to a touch sensor of the touch screen device through the base assembly.
