<p>PROBLEM TO BE SOLVED: To perform stable vibration detection regardless of vertical displacement of a water tub of a washing machine, in a safety switch which detects abnormal vibration of the water tub.SOLUTION: A safety switch includes a guide part which linearly moves a detection lever provided correspondingly to a vibrating water tub. The guide part is constituted of a guide member having a guide part which guides in a linear manner and a movement member which is guided by the guide part and moves linearly in the direction, and a safety switch is configured by including a switch part which operates in response to the movement of the movement member. The detection lever changes the vibration of the water tub into a linear motion, and can perform correct detection without being affected by a vertical displacement of the water tub.</p> |
