<p>A magnet holding relay with an improved magnetic path structure comprises a magnetic path part. The magnetic path part comprises a U-shaped yoke (32), magnetic steel (35), an armature (33), a bobbin (31), and a winding (34). The armature is mounted at the outside of an opening of the yoke. A middle part of the armature is provided with a rotating shaft (331) capable of moving in a seesaw manner. The rotating shaft is disposed opposite a middle part between two arm ends of the yoke, thus two ends of the armature are alternately moved towards a corresponding end of the two ends of the yoke when the armature is moved in a seesaw manner. The magnetic steel is spliced at a surface of the armature towards the yoke, and positioned between two arm ends of the opening of the yoke without contacted with the two arm ends of the yoke. Magnetization direction of the magnetic steel is set to be in parallel with the two arms of the U-shaped yoke. Magnetic loops with different directions are correspondingly and alternately formed in the armature and the yoke when the two ends of the armature are alternately moved towards the yoke. The structure is a balanced type magnetic path, thus disadvantages of original unbalanced structure are prevented. The relay is simple in structure, and can be manufactured in an inexpensive manner.</p> |
