A contact point control device is provided to remove vibration by maintaining a contact point without a power. In a contact point control device, a fix-releasing unit(10) with a fixing unit, which fixes and releases a displacement unit(11) and the other displacement unit, is added to a crossbar with a displacement iron core and a displacement contact point. An electricity is applied to a coil. The displacement iron core, the displacement contact point, the crossbar, the displacement unit(11), and the other displacement unit are displaced by a magnetic force of an iron core added to the coil. The displacement contact point is contacted to a fixed contact point(110). A protruded screw thread added to the other displacement unit is fixed to the fixing unit.
