Zusammenfassung:	TITLE: AXIALLY SYMMETRIC PUSHROD FOR A HIGH-VOLTAGE DC Abstract An axially symmetric pushrod for a high-voltage DC relay, comprising a pushrod; an upper section of the pushrod is located above a yoke and fixed with a moving contact assembly; a yoke through hole for allowing a middle section of the pushrod to pass therethrough is formed on the yoke; a lower section of the pushrod is located below the yoke and fixed with a moving iron core; the moving iron core is located within a magnetic conductive drum; a via hole running through the pushrod radially and/or an open slot extending radially and inwardis formed on the upper section of the pushrod; a plastic limiting block is fixed on the upper section of the pushrod by injection molding; and, part of material of the plastic limiting block is located within the via hole or the open slot; the plastic limiting block is of an axially symmetric structure using an axis of the pushrod as its axis. 10 b 10 bi 8:
