Abstract:
PURPOSE: To shorten the axial length of a finger contact regularly keeping the electric connection between a movable conductor delivered from a switch and a solid conductor in a solid insulating switchgear having the switch received in an insulating cylinder.
CONSTITUTION: The finger part 21a of a finger contact 21 is formed of a base end part 21a2 having a comparatively thin form with nearly a fixed diameter and a top end part 21a1 having a thick form in which the diameter is gradually reduced as the contact part with a movable conductor 21 gets close to.
