The invention discloses a small anti-high-overload touch switch. The small anti-high-overload touch switch comprises a base, a protective cover, an outer electrode, an inner electrode, an outer electrode insulating seat, an inner electrode insulating seat and a packaging structure, wherein a stepped cavity with different apertures is formed in the base; the protective cover, the outer electrode and the inner electrode are each a hollow conical-surface shell with an arc top, the edge of the bottom of each shell is turned outwards, and the protective cover is installed in the stepped cavity of the base; the outer lateral surface of the outer electrode insulating seat is tightly attached to the outer electrode; the inner electrode is tightly attached to the bottom surface and the inner lateral surface of the outer electrode insulating seat and is installed in the stepped cavity of the base; the inner electrode insulating seat is tightly attached to the inner electrode and arranged in the stepped cavity of the base; the packaging structure with a through hole is tightly attached to the bottom surface of the inner electrode insulating seat, installed in the stepped cavity of the base and fixedly connected with the base. According to the small anti-high-overload touch switch, the inner electrode and the outer electrode are independently arranged and insulated with the base, and the anti-interference capacity is high, and mistaking triggering caused by static electricity or ionization and triggering failure after touching in a high-speed movement environment are prevented.
