Problems solved by technology
[0006] Therefore, conventionally, the structure for transmitting pressure to piezoelectric ceramics is complicated, and at the same time, when the structure for transmitting pressure is attached to a corresponding product, there is a problem that pressure cannot be easily transmitted due to variations in the attachment method.
[0007] In the past, when a pressure switch was applied to a metal body, there was a problem that the peripheral keys were recognized at the same time due to the rigidity of the metal.

Embodiment Construction
[0027] Hereinafter, the pressure switch device of the present invention and a printed circuit board having the same will be described with reference to the drawings.
[0028] figure 1 It is a perspective view showing a first example of the pressure switch device of the present invention.
[0029] refer to figure 1 , The pressure switch device of the present invention is provided on a printed circuit board, and has a substrate portion 100 provided with a sensor (not shown).
[0030] The substrate portion 100 has a thickness of 0.1t to 1.0t and is formed of a flexible material.
[0031] The substrate part 100 is pierced with one or more holes 110 .
[0032] Wherein, preferably, the hole 110 is pierced into a circle or a polygon. The purpose of being pierced into a circle or a polygon may be to induce such that the pressure transmitted to the outside of the hole 110 is dispersed when pressure is applied to a sensor described later.
[0033] Furthermore, a rib 120 is formed o...

The present invention presents a pressure switch device. The pressure switch device includes: a substrate part, which is formed of a flexible material, has a hole punched therein, and has a rib extending from an inner circumference of the hole and being bendable by an external force toward a sensor disposed at an adjacent position; a contact part provided on the rib and forming contact with the sensor by the external force; a holder part fixed to the substrate part so as to be disposed in a peripheral region of the hole and on an upper end portion of the rib; and a disk-shaped piezoelectric sensor disposed between the substrate part and the holder part and supported by the holder part. In addition, the present invention also provides a printed circuit board having the pressure switch device.
Description
technical field [0001] The present invention relates to a pressure switch device, and more specifically, to a pressure switch device and a printed circuit board having the pressure switch device in which pressure is concentratedly transmitted to a target position and at the same time, pressure outside the target position is transmitted In this case, accurate switching operation can be performed by distributing the transmitted pressure. Background technique [0002] In general, recently, as an input unit for controlling operations of various electric and electronic devices, a touch input device using a device for detecting a touch (for example, a touch detection device) exists and is developed. [0003] In principle, a touch detection device is a device that recognizes a touch, and a touch input device is a device that is used as an input unit by performing touch detection to output a detected touch as a signal, but in practice, the two are not used much. the difference. ...
