Abstract

PURPOSE: To simplify the structure as well as to reduce the size by applying the reaction force, due to a contact pressure of a movable contact element which has rollers, to a guide arm of a drive insulation plate.
CONSTITUTION: When a drive insulation plate 4 shifts a required distance, a movable contact element 3 connects two adjoining fixed contact elements among several fixed contact elements that are arranged on a straight line; thus tap switching is done. Upon switchging, the contact pressure required to energize is given by the elasticity of the movable contact element 3, and its reaction force is applied to both a supporting insulation plate 2 and the drive insulation plate 4. Nevertheless, reduction of the contact pressure of the movable contact element 3 does not occur, because freely rotating rollers 6 that are fixed to a guide arm 5 of the drive insulation plate 4, are in contact with the plate 2.
