ELECTRIC CURRENT SWITCHING APPARATUS

摘要

Disclosed is an electric current switch apparatus, wherein a fixed-side electrode unit and a movable-side electrode unit are positioned in opposition with a respective common central axis therebetween, and which switches electric current that flows between the electrodes by a movable contact element, which is disposed upon the movable-side electrode unit, shuttling along the central axis and contacting and separating from a fixed contact element, which is disposed upon the fixed-side electrode unit. The electric current switch apparatus comprises a plurality of permanent magnets, which are disposed upon at least one of the fixed-side electrode unit and the movable-side electrode unit, each respective main body being positioned upon the center axis, the respective directions of magnetism being aligned in the center axis direction, and adjacent pairs of permanent magnets are made to abut such that the same poles in each pair are facing one another.
