Abstract
A contact arrangement for a vacuum switch, which includes a stationary contact member, a movable contact member, and exactly one coil member. The movable contact member has an axis of motion that extends to the stationary contact member. The stationary contact member and the movable contact member are each in the form of a cup with a cylindrical side wall having a multiplicity of slots inclined at an angle with respect to a circular bottom wall, the orientation of the slots of the stationary and movable contact members being substantially the same. Each of the contact members also has a circular contact disk that engages the side wall opposite the bottom wall. Circumferentially-directed components of electrical current flowing in the side walls of the stationary and movable contact members generate an axial magnetic field that is substantially parallel to the axis of motion of the movable contact member. The coil member has a path for electrical current to flow in approximately the same direction as the circumferential direction of the circumferentially-directed components of electrical current flowing in the side walls of the stationary and movable contact members. An electrical current that passes through the coil member generates a magnetic field that has an axial component that is substantially parallel to the axis of motion of the movable contact member, the coil member magnetic field amplifying the axial magnetic field generated by the contact members.
