Abstract
(EN)
Disclosed in the present application are a knob cap fixing assembly and a knob switch. The knob cap fixing assembly comprises a knob cap, a snap ring, and a knob having a knob rotating shaft; the knob rotating shaft is provided with a groove; the knob cap and the snap ring are both sleeved on the knob rotating shaft, and the snap ring is located in the groove and is in tight fit with the knob cap. Based on this, the present application can still subject the knob cap to large tightening force after multiple insertions and removals, and is thus beneficial to avoid the loosening of the knob cap.
