<p>PURPOSE: A DC(direct current) relay unit is provided to prevent a phenomenon which an operating contact point is separated from a fixed contact point by decreasing a magnetic flux. CONSTITUTION: A pair of fixed contact points(20,21) applies voltages to respective opposite directions. An operating contact point(22) is separated from the fixed contact point or is connected to the fixed contact point. A pair of permanent magnets arranges arc at the outside. A pair of permanent magnets arranges an arc to outside. Damping magnets(33,34) reduce a force generated to a direction where the operating contact point is separated from the fixed contact point. The damping magnets include a first and a second damping magnet.</p> |
