  • Contact-breaker device, circuit and apparatus comprising the same, and method for assembling contact-breaker device
    Patent number: 7566839
    Abstract: A contact-breaker device that can be miniaturized, realize low power consumption and low cost, and generate an irregular pulse current by causing irregular electrical conduction and insulation of a circuit. The contact-breaker device comprises: fixed terminals 12A and 12B secured at positions spaced apart from each other; and a movable member 11 capable of moving relative to the fixed terminals 12A and 12B and coming into or avoiding contact with the fixed terminals 12A and 12B based on its movement, thereby causing electrical conduction or insulation between the fixed terminals 12A and 12B; wherein the movable member 11 irregularly moves in accordance with externally applied vibration, thereby causing irregular electrical conduction or insulation between the fixed terminals 12A and 12B.
