Furthermore, a communication port between the cavity and the outside is formed in one side close to the pressing end.

Furthermore, the structure of the elastic support leg is a ring-shaped structure corresponding to the outer contour of the main body.

Furthermore, the contact comprises two elastic supporting legs which are respectively arranged at two sides of the contact.

Furthermore, the section of the elastic supporting leg parallel to the pressing direction is of a trapezoid structure, and the shorter side of the trapezoid structure is closer to the metal elastic sheet.

Further, the elastic legs and the contacts are designed integrally.

The utility model also provides an outdoor handheld terminal, including foretell button structure.

Based on the technical scheme, the elastic support legs are arranged at the side edges of the contact, when no external force acts, the elastic support legs pre-tighten the support main body to separate the contact from the metal elastic sheet, so that the contact is prevented from being directly contacted with the metal elastic sheet, and the condition of misoperation caused by mistaken pressing is reduced; through set up the cavity at the elasticity stabilizer blade, reduce weight, reduce and drive the required pressing force of metal shrapnel is so that press the sense of touch comparatively comfortable.
