圧開閉器。[Claims for Utility Model Registration] (1) An insulating material containing a cavity, and an axis of a through hole drilled in the insulating material in the middle of the cavity, and an axis of the cavity. two fixed contacts spaced apart from each other; a terminal connected to each of the fixed contacts and penetrating the side of the insulator in a watertight manner; and a through hole in the fixed contact; A sliding contact that is slidably inserted between the fixed contacts and electrically closes or opens a circuit between the fixed contacts, and between the upper or lower end of this sliding contact and the top or bottom of the cavity of the insulator. 1. A low-voltage switch comprising a spring provided therein, which spring does not deform at room temperature, but deforms as if expanding in the axial direction at a constant temperature. (2) The low voltage switch according to claim 1, wherein the spring is formed of a shape memory alloy material.
