Abstract: A contact mechanism of an electromagnetic relay comprises a contact assembly, a movable contact assembly and a driving unit. The contact assembly comprises a bottom plate, an upper case disposed on the bottom plate, and two stationary contact heads disposed on and penetrating the upper case. The movable contact assembly comprises a central axis passing through the contact assembly, a movable contact plate disposed on the top portion of the central axis and configured to contact with or separate from the two stationary contact heads, and a cover element covering the central portion of the central axis. The driving unit is disposed around the lower portion of the central axis and configured to drive the central axis to move back and forth along the axial direction for allowing the movable contact plate to contact with or separate from the two stationary contact heads.

Abstract: A magnetic assembly includes a magnetic core, a magnetic core set, a circuit board and a positioning plate. The magnetic core set includes a first magnetic member, two second magnetic members and a plurality of third magnetic members. A plurality of separation spaces exist between the first magnetic member and two second magnetic members, and the circuit board is disposed between the magnetic core and the magnetic core set. The positioning plate has a first receptacle configured to receive the first magnetic member, two second receptacles each configured to receive one of the second magnetic members, and a plurality of third receptacles configured to receive the third magnetic members. Therefore, the eddy current loss and the winding loss are reduced, the sizes of the separation spaces are controlled precisely, and the advantages of enhancing the effectiveness of the magnetic assembly are achieved.
