The invention aims to solve the problem that the existing double-steel-magnet differential relay pusher group only contacts reeds on one side. According to the pusher group applicable to double-steel-magnet differential relays in the invention, surface contact between pushers and movable reeds is realized by clamping the edges of the movable reeds from two sides, and the means of self-return of the movable reeds is changed into the means of armature-driven return so as to suppress collision bounce between the movable reeds and a back static reed in the release process of a double-steel-magnet differential relay. According to the using method of the pusher group applicable to double-steel-magnet differential relays, an armature applies pressure to the movable reeds by making use of holding force provided by steel magnets in the release position. The anti-vibration performance is improved, the pull-in voltage is reduced, pull-in is facilitated, the sensitivity of an electromagnetic system is improved, and the phenomenon of two-step pull-in is inhibited.
