<p>The present invention relates to a no-load tap switcher including: a fixed insulation tap plate which is formed in a longitudinal direction and on which multiple combination grooves are formed; multiple fixed contact points which are formed on the combination grooves of the fixed insulation tap plate; a pair of moving contact points which is in contact with the two fixed contact points, respectively; a gear box which equips a moving rack gear and a pinion gear which move the moving contact point; a driving shaft which supports around the center of the gear box; and a driving handle which moves the driving shaft. The present invention consists of a plurality of input lines and a plurality of output transformations and increases efficiency without the generation of resistance due to transformation without error and easy movement of an electric contact point of a tap. Each deviation reduces since multiple taps use the same shaft. Also, the structure of vibration absorption, waterproof, and airtight is adopted to a driving device and quality and stability are secured.</p> |
