When a push-type key switch is employed, a silicone sleeve is provided over the key switch. The cross-shaped silicone connecting rib at the front of the silicone sleeve elastically abuts against the key cap, creating an elastic, interlocking abutment. This results in a quieter, more comfortable press when the key cap is pressed. When a rotary switch is employed, the silicone sleeve is not required. Instead, the key base is provided with a recessed area for inserting the rotary switch's knob rod. Due to the tight riveted connection between the key base and key cap, twisting the key cap activates the key base, thereby driving the knob rod of the key switch. A single set of key cap molds can accommodate both push-type and rotary switches, reducing R&D costs. BRIEF DESCRIPTION OF THE DRAWINGS
