Abstract An axial motion switch which consists of a magnetic material armature attached to an end cap of a sealed vessel by means of a spring, flexible contact wire, or the like. The other end of the sealed vessel is provided with a magnetic, internally extended end cap which forms a pair of contacts with the free end of the armature. The two end caps are electrically insulated from each other by using a vessel of insulating material, such as glass or a metal vessel suitably insulated from the end caps. When the vessel is placed in a magnetic field of correct orientation, the armature is attracted axially by mutual magnetic pole induction to the internally extending end cap and the contact therebetween causes a low electrical resistance path to exist between the end caps of the switch device.

Claim 1
Independent Claim
172 words
A circuit closing device operable by magnetic forces, comprising a metal envelope having an opened end, a glass header mounted within said opened end to provide a hermetic seal between said glass header and said envelope, a pole mounted within and secured to the base of said envelope, a coil spring secured at one end to said pole, an armature mounted on the free end of said coil spring and axially spaced from said pole, an insulation spacer mounted on one end of said armature opposite the end axially spaced from said pole, a bridging contact mounted on said insulation spacer, a pair of connectors mounted in said glass header and having connector ends within said envelope in contact with said bridging contact, an energizing coil provided surrounding said envelope and connected to a source of current so when energized said armature overcomes the retractile force of said spring to contact said pole and axially displace said bridging contact from said connector ends to open the circuit between said pair of connectors.
