Abstract
A keypad assembly includes a support member, a key switch, a rotation member 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 rotation member is rotatably connected to the keycap. The resilient member includes resilient latching portions latching with the rotation member. The resilient member fixedly interconnects the rotation member and the support member. The rotation member is rotated relative to the resilient member at an angle when the key switch is not triggered, such that the resilient member provides an elastic torque to the rotation member.
