摘要: A switch device capable of safely opening an electrical circuit in response to an abnormality such as wetting with water or liquid leaking from a battery. The device includes a first conductor connected to an external circuit and having a relatively high ionization tendency, and a second conductor arranged close to the first conductor and having a relatively low ionization tendency which is lower than that of the first conductor, a reaction part which electrically corrodes the first conductor is formed by a liquid between the first and second conductors.

摘要: A fuse element comprises a low melting point metal layer, a first high melting point metal layer having a higher melting point than a melting point of the low melting point metal layer, and a restricting portion including a high melting point material having a higher melting point than a melting point of the low melting point metal layer and configured to restrict flow of the low melting point metal or deformation of a layered body constituted by the first high melting point metal layer and the low melting point metal layer.

摘要: A switch device capable of safely opening or short-circuiting an electrical circuit in response to an abnormality such as wetting with water or liquid leaking from a battery is provided. The device includes first and second conductors connected to an external circuit, and a reaction part including an insulating material which changes state on contact with a liquid, the first and second conductors being electrically connected or disconnected by the insulating material changing state on contact with the liquid.
