Abstract
A keypad assembly includes a support member, a key switch, a keycap, and a resilient member. The key switch is fixed on the support member and includes a triggering portion. The keycap is located opposite to the triggering portion. The resilient member includes a rotation portion and a resilient support portion connected to the rotation portion. The rotation portion is rotatably connected to the keycap and the support member. The resilient support portion is elastically deformed via resisting the support member when the key switch is not triggered, and provides an elastic restoring force to the rotation portion.
