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 coil winding includes a coil. The coil has a first winding segment and a second winding segment. The first winding segment includes a first lead. The second winding segment includes a second lead. The first winding segment is stacked as a first winding portion, and the first lead is connected with the first winding portion. The second winding segment is arranged along a lateral direction as a second winding portion, further arranged on the second winding portion along a lateral direction as a third winding portion, and further arranged on the third winding portion along a lateral direction as a fourth winding portion, and the second lead is connected with the fourth winding portion. Therefore, the space where the first lead located at is directly and sufficiently used, none of any extra space is occupied, hence the space can be effectively utilized.
