Abstract
An apparatus to detect opening and closing of a door in a washing machine by detecting a resistance value varying according to a lever position of a door lock switch. In the apparatus to detect opening and closing of a door in a washing machine, since a resistance meter is added to the inside of a component with the contact being eliminated therefrom, it may be possible to simplify an inner structure of the component and to reduce material costs. In addition, opening and closing of a door is accurately detected as a resistance value of the resistance meter varies by rotation of a gear instead of surface contact between contacts, and thus it may be possible to prevent a detection error in the event of contact short circuits due to moisture and to enhance component reliability.
