Embodiments disclosed provide a switching and operating assembly of a switch. The switch includes a switching assembly including a switching member adapted to move between at least two positions to control an operation state of the switch; and a driving member coupled to the switching member; an operating assembly separated from and detachably arranged on the switching assembly and operable to cause the driving member to rotate; and an elastic component arranged between the switching member and the driving member to hold the switching member in one of the at least two positions. By providing the switch including a switching assembly and an operating assembly separated from each other, any one of the switching assembly and the operating assembly can be replaced separately without changing the overall height of the switch. This significantly increases the flexibility to personalize the switch.
