A rotary knob assembly (100) includes a fixed raised boss (110) having a boss cavity (107) and a knob (102) optionally having a rotary switch stem (104) therein. The knob can include a portion that axially resides within the boss cavity such that impacts to the knob transfers to the fixed raised boss. The knob can further include a rigid core member (106) and an outer over-molded portion (108) over-molded on to the rigid core member. The fixed raised boss can include an outer circumference (118) and an inner circumference (116). The inner circumference of the boss and a portion of the rigid core member and the outer circumference of the boss and the outer mover-molded portion form a knob-boss interface (117) that sustains impacts to the rotary knob assembly while isolating a rotary switch (112) from impacts.
