PURPOSE: A limit switch is provided to secure a stable operation without damage or deformation by damping an external shock through a housing and a shock damping device. CONSTITUTION: A limit switch is fixed inside a housing(110). A shock damping unit is formed in one side of the limit switch and absorbs the external force transmitted to the limit switch. The shock damping unit includes a first pin(131), a second pin, a first spring, and a second spring. A moving bracket is arranged between the first spring and the second spring and moves inside the housing according to the movement of the first pin. The second pin is arranged in the first pin and is engaged with the limit switch by passing through the moving bracket. One side of the second pin is engaged with one side of the first spring. The other side of the second pin is engaged with the limit switch.
