The knob switch may be disposed behind the surface panel. The knob switch may include an internal spring and a slidable stem extending through a central axis. The slidable stem may be in forward-biased mechanical communication with the internal spring. The support plate may be rotabably mounted about the slidable stem. The control body may be mounted to the slidable stem. The control body may be rotationally fixed to the support plate and slidable relative thereto. The control body may include a primary grip extending about at least a portion of the slidable stem. The central projection may be disposed radially inward from the primary grip and define an axially fixed stop surface disposed forward from the control body.
