Abstract
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 a conductor connected to an external circuit, and a reaction part including a liquid-soluble material which opens the conductor and the external circuit and which dissolves on contacting a liquid entering the device interior to electrically connect the conductor and the external circuit.
Claims18
A switch device comprising:
- a conductor connected to an external circuit;
- and
- a reaction part comprising a liquid-soluble material which opens the conductor and the external circuit and which dissolves on contact with a liquid entering an interior of the device to electrically connect the conductor and the external circuit.
A protective device comprising:
- a first and a second electrode;
- a heat generator;
- a fusible conductor which is connected between the first and second electrodes and which is blown out by heat generated by the heat generator;
- and
- a switch part provided on a power supply path of the heat generator, wherein the switch part comprises a conductor connected to a power source circuit of the heat generator, and a reaction part comprising a liquid-soluble material which opens the conductor and the power source circuit and which electrically connects the conductor and the power source circuit by being dissolved on contact with a liquid entering a device interior.
