A door switch for a washing machine is provided to restrain breakdown of insulation by preventing a conductive passage between a heater and a rib from being formed by improving the shape of the rib. A door switch for a washing machine includes a door switch body(50), a fixed terminal(84), a movable terminal(86), a bimetal(100), a heater(110), and a plurality of ribs(121,122,123,124). The door switch body is installed in the washing machine so as to catch a hook of a door. The fixed terminal is installed in the door switch body. The movable terminal is installed in the door switch body so as to make contact with the fixed terminal. The movable terminal is in contact with the fixed terminal by the bimetal brings. The ribs protrude from the door switch body so as to make contact with one end of the heater. The portions of the rib except for the end of the heater are spaced apart from the heater.
