Dual-stroke safety switch of washing machine and eccentricity control method
A dual-stroke safety switch of a washing machine has a control switch mounted in a base, and a control rod movably connected to the base. The control switch comprises a first control switch and a second switch. The control rod has two motion strokes respectively for controlling the switch-off of the first control switch and the second switch, and the motion stroke for the switch-off of the first control switch is less than the motion stroke for the switch-off of the second control switch. The different strokes of the control rod substantially reflect different degrees of eccentricity of a water tub. The switch-off of the first control switch indicates that small eccentricity of the water tub takes place, and the switch-off of the second control switch indicates that there is serious eccentricity.
