Abstract: Systems, methods, techniques and apparatuses of contactors are disclosed. One exemplary embodiment is a contactor including an electric pole, a pair of plungers, and a pair of opening springs. The electric pole includes a fixed yoke member and a movable yoke member arranged respectively at a proximal position and a distal position with respect to a movable contact. The fixed yoke member includes a pair of through holes. The pair of second plungers are inserted in a corresponding through hole passing through the fixed yoke member and symmetrically positioned with respect to a main symmetry plane of the contactor, which is parallel to a displacement axis of the movable contact and perpendicular to a displacement plane of the movable contact. The pair of opening springs are symmetrically positioned with respect to the main symmetry plane.

Abstract: A contactor (1) comprising: one or more electric poles (3); for each electric pole, a fixed contact (31) and a corresponding movable contact (32), the one or more movable contacts (32) of said contactor being reversibly movable, along corresponding displacement axes (33) mutually parallel and lying on a common displacement plane (34), between a first position (A), at which said movable contacts are decoupled from the corresponding fixed contacts, and a second position (B), at which said movable contacts are coupled with the corresponding fixed contacts; a movable armature (7) reversibly movable, along a corresponding displacement direction parallel to the displacement axes (33) of said movable contacts, between a third position (C) and a fourth position (D); for each electric pole, a first plunger (8) coupled with said movable armature (7) and with a corresponding movable contact (32), each first plunger extending along a corresponding main longitudinal axis parallel or coinciding with the displacement axi
