摘要：Disclosed is a dual-stroke safety switch of a washing machine, comprising a control rod, a base (6) and a control switch, wherein the control switch is mounted in the base (6), the control rod is movably connected to the base (6), the control switch comprises a first control switch (3) and a second switch (4), the control rod has two motion strokes respectively for controlling the switch-off of the first control switch (3) and the second switch (4), and the motion stroke of the control rod corresponding to the switch-off of the first control switch (3) is less than the motion stroke of the control rod corresponding to the switch-off of the second control switch (4). The different strokes of the control rod corresponding to the motions of the first control switch (3) and the second control switch (4) of the above-mentioned safety switch substantially reflect different degrees of eccentricity of a water tub, the switch-off of the first control switch (3) indicates that the eccentricity of the water tub takes place, however, the degree of eccentricity is not big, and the switch-off of the second control switch (4) indicates that there is serious eccentricity in the water tub.Therefore, the above-mentioned dual-stroke safety switch can control stable and smooth starting of the drying of the fully automatic washing machine and reduce vibration.
