Washing machine

A washing machine comprising:

• a casing (C);
• and
• a state sensing unit (60) being configured for sensing tilt of a predetermined angle or more of the casing or vibration of a predetermined magnitude or more applied to the casing,
• wherein the state sensing unit (60) includes:
• a switching conductive element (630) being configured to move according to the tilt or the vibration;
• a contact electrode (610);
• and
• a guide electrode (620) being configured to guide movement of the switching conductive element (630) and to be electrically connected to the contact electrode (610) through the switching conductive element (630) when the switching conductive element contacts the contact electrode (610) and the guide electrode (620).
