  • Patent number: 4072835
    Abstract: A resettable switch is disclosed having a conductor maintained in contact with a reservoir of mercury to conduct current therethrough during normal operation. During impact or roll over, the mercury is spilled from the reservoir and prevented from returning thereto by cone-shaped retainers maintained in a telescoped relation by a spring, thereby opening the switch. The switch may be reset by depressing a plunger which aligns slots in the telescoped retainers, which permits mercury to return to the reservoir.
