PURPOSE:To reduce impulse voltage impressing to a tap winding and to simplify structure of the title item by a method wherein a nonlinear resistor is assembled to a tap switch and disposition thereof is performed between each of adjacent fixed contact. CONSTITUTION:A terminal conductor 5 holding each fixed contact 4 of a tap switch 3 between each conductors 5 is penetrated and inserted into an insulated cylinder 8 placing on a nonlinear resistor 7. That is, the insulated cylinder 8 possesses a slit 9 facing thereto in axial direction, and the terminal conductor 5 is stacked mutually with the nonlinear resistor 7 to a base support 10 through a mild spring 11, then is fixed and is constituted putting the upper suppot 12 to the top stage. A moving contact 6 is provided to an arm 13 with a rack unit so as to slide and contact with the fixing contact 4, and then the end thereof is grounded. |
