    Abstract: A pressure switch configured to be disposed on a path, through which dust passes, to control a dust sensor according to whether a suction pressure is formed in the path, is provided. The pressure switch includes: a body part having a connection tube connected to the path, and an upper surface; first and second terminals configured to be electrically connected to the dust sensor, and at least a portion of which protrudes from the upper surface of the body part; and a flexible cap configured to engage the body part to define a space along with the upper surface of the body part. The flexible cap is deformed in response to a negative pressure being formed in the space, thereby electrically connecting the first and second terminals.
