Abstract
A pressure switch device is disclosed. The pressure switch device includes a substrate formed of a flexible material, provided with a hole perforated therethrough, and including a rib extending from an inner circumference of the hole and being bendable toward a sensor disposed adjacent thereto by an external force, a contact portion disposed on the rib and forming a contact point with the sensor by the external force, a holder unit fixed to the substrate to be disposed on a peripheral area of the hole and an upper end of the rib, and a piezoelectric sensor disposed between the substrate and the holder unit, supported by the holder unit, and having a disc shape. A printed circuit board includes the pressure switch device.
