Abstract

The invention provides a mobile phone side key. A key slot comprises an outer segment slot and an inner segment slot, and a step is formed at the joint of the outer segment slot and the inner segmentslot. An elastic part is built in the inner segment slot, and the outer end extends into the outer segment slot and is provided with a press part. The outer periphery of the press part is located on the step, and an elastic reset member is arranged between the elastic part and the step. Elastic support legs are arranged on both ends of the elastic part, and an arc-shaped protrusion is arranged onthe outer side of each elastic support leg. Each arc-shaped protrusion and the inner segment slot are in interference fit. Elastic protrusions and conductive bases are arranged on the inner side of the elastic part. A support frame is arranged on the inner side of the side wall of a mobile phone casing. Both ends of the support frame are fixed on the side wall of the mobile phone casing. The support frame is provided with a support column and through holes. The elastic protrusions pass through the through holes. The support frame and the support legs are engaged through clip heads and clip slots. An adhesive layer is arranged between a clip head and a clip slot. According to the invention, the mobile phone side key is easily assembled; linkage is avoided; and the hand feeling of press is improved.
