摘要： A resettable impact switch is disclosed having a housing (12), a first terminal (22) and a second terminal (26) secured to the housing, and a moveable conductor (44) maintained in contact at one end with a reservoir of mercury and at the opposite end with the second terminal (26). The reservoir of mercury is, in turn, in contact with said first terminal (22), allowing the conduction of current through the switch when the moveable conductor (44) is connected to said second terminal (26) and said reservoir of mercury, as during normal operation thereof. Upon a predetermined level of impact imparted to said switch or upon inversion thereof, the connection between the conductor (44) and mercury is broken, thereby opening the switch. The switch is maintained open until a resetting operation is performed. The connection between the opposite end of the conductor can also be broken to de-activate the switch.
