Abstract
A control knob assembly for a cooktop appliance provides a readily visible indicator of the power level of a heating element. The control knob assembly includes a control knob that is rotatably mounted to a center housing and defines an arcuate light display and contact features that extend toward the center housing. A stationary shutter that defines an arcuate aperture is fixedly positioned between a light source and the control knob for at least partially allowing light from the light source. A mobile shutter is positioned between the stationary shutter and the control knob and includes an axial paddle extending along the axial direction for engaging the contact features as the control knob is rotated, thereby rotating a radial shutter for blocking a portion of the arcuate aperture.
