Description of the Invention: [Technical Field] The present invention relates to a touch panel, and more particularly to a touch panel having a switch function. [Prior Art] [0002] Ο 〇 [0003] Touch The Touchpad is the main input device for laptops. It is used to control the screen cursor and functions as a mouse. The first touchpad was invented by George E. Gerpheide and first integrated by Apple Computer in 1994 on PowerBook 5. ...0.0. Department, column, on the computer 'has gradually become the standard configuration of the notebook. Currently, the touch panel products on the forefront mainly include two technologies, one based on the principle of capacitance and the other based on the principle of resistance. The touch panel of the capacitor principle is converted into the movement of the cursor by the capacitance change between the finger and the touch panel of the touch panel, and the touch panel of the resistance principle is composed of a deformable resistive film and a fixed resistive film. The middle is separated by the air phase, and when the palm touches the touchpad, the upper resistive film is pressed to make a pen shape and is in contact with the lower layer and the resistive film, and the lower resistive film can sense the position of the finger, thereby controlling the movement of the cursor. Laptop manufacturers usually install a button switch equivalent to the left and right buttons of the mouse on the accessory of the touchpad. However, when using the computer, the user needs to control the touchpad with different fingers and press the button switch, which is inconvenient for operation. SUMMARY OF THE INVENTION [0004] In view of the above, it is necessary to provide a touch panel that is easy to operate. [0005] A touch panel includes a touch panel, a base, an insulating layer fixed on a lower side of the touch panel, and a touch circuit board, and a switch 098124521 is fixed on the base.

Compared with the prior art, the touch panel of the present invention can realize the function of controlling the cursor movement and pressing the switch with one finger, and is convenient to use. [Embodiment] Referring to FIG. 1 and FIG. 2 in May, a preferred embodiment of the touch panel of the present invention comprises a touch panel 20, an insulating layer 30, a sensing circuit board 4, a base 50, and a switch. 60 and a plurality of springs 70. The touch panel 20 is located at the outermost side of the touch panel for finger touch, and is provided with a downwardly extending sleeve 21 at each of the four corners. Each of the columns 21 is provided with a central hole 24 1 . Below the touchpad 20, the side is provided with a square receiving cavity 25. The insulating layer 30 is located between the touch panel 20 and the touch-sensitive circuit board 40 for electrically isolating the touch panel 20 from the touch-sensitive circuit board 40. A wire mesh is formed on the upper surface of the touch-sensitive circuit board 40. The wire mesh is determined by the capacitance thereon to determine the position and movement trajectory of the finger, and an interface 43 is set on the lower side of the sensing circuit board 40 for sensing the wire mesh. The signal is transmitted to the processor, and the processor controls the cursor on the computer screen to perform the corresponding action. The base 50 can be fixed on the base of the notebook computer. The four corners of the base 50 corresponding to the cover post 21 of the touch panel 20 are provided with four uprights 51. The base 50 is raised in the middle to form a fixing portion 53 for fixing the switch 60. The fixing portion 53 is provided with four fixing holes 5 31 extending through the base 50. One side of the fixing portion 53 is provided with a notch 532 for the interface 43 of the sensing circuit board 40. A switch 61 is disposed on the upper portion of the switch 60, and four pins 63 are disposed on the lower portion. Form No. A0101 Page 4 of 12 0982041876-0 [0012] 201104518 [0013] ❹ [0015] 〇 [0015].
