Abstract: A control knob includes a control rod assembly including a base plate, a control rod, and an electronic circuit board, a display connected to receive an electrical signal from the electronic circuit board and including a display front face that displays a device status, a knob including a knob aperture wall, and a cover mounted between the knob and the base plate and including a cover sidewall that mounts to the base plate, a cover front wall mounted to the cover sidewall to cover an interior of the cover sidewall, and a display aperture wall formed in a portion of the cover sidewall and a portion of the cover front wall. The display aperture wall allows insertion of the display housing. The control rod assembly, the display, and the cover rotate with the knob when the knob is rotated. The display front face is visible through the knob aperture wall.

Abstract: A knob assembly includes a knob, a light assembly, a light socket, and a receptacle. The light assembly includes a light diffuser, a light source, and a light connector prong. Light from the light source is transmitted through the light diffuser. The light connector prong is electrically connected to the light source to provide power to the light source when the knob is rotated. The light socket includes a socket housing, a light connector aperture wall, an electrical connector aperture wall, and an internal conductor. The light connector prong is mounted within the light connector aperture wall. A power connector prong connectable to a power source is mounted within the electrical connector aperture wall. The connector housing of the receptacle is configured to house the light socket. The light connector prong is inserted into the light connector aperture wall through a first wall of the device.

Abstract: A knob assembly for a gas cooktop is provided that includes a receptacle mounted between a valve and a knob. The knob directly mounts to a knob control rod and is configured to mount in a vertical plane perpendicular to a plane defined by a horizontal support surface for a cooking receptacle. The receptacle includes a receptacle abutment wall, a receptacle wall extending from the receptacle abutment wall, and a control rod aperture wall formed through the receptacle abutment wall. The control rod aperture wall is sized and positioned to support insertion of the knob control rod therethrough. The receptacle abutment wall is configured to abut a back of a control panel when the knob assembly is mounted to the control panel. The receptacle wall is sized and positioned within a knob aperture wall formed through the control panel when the knob assembly is mounted to the control panel.
