The upper cover group of the group 63 has a button 64 that can be pressed to form the electrical contact group 63, and the bottom edge 64 of each button forms a resistance to the soft circuit board 61 to prevent short circuit and damage caused by the entry of water or liquid, and corresponds to the metal substrate 6 An air guiding hole 65 is formed in a central portion of each of the contact groups 63 for the button 64 to press the gas, and the movement is adjusted as shown by the arrow 66 to make the operation smooth, although the case is on the second surface 67 of the metal substrate 6 away from the first surface 60. There is a sight glass 68, but it is only used for visual observation with the M315399. The air guiding hole 65 is not absolutely blocked, so that impurities or fine dust cannot be absolutely prevented from being blocked by the second surface 67 or by the air guiding hole. 65 The internal 641 of the entry button 64 is blocked, hindering the smooth operation thereof or causing the misalignment or short circuit damage of the electric contact group. Therefore, how to construct the second surface of the metal substrate, the communication air holes located under the button are electrically connected to each other. The air guiding groove, and a sealing member on the second surface including a part or all of the air guiding hole and the air guiding groove portion, as a waterproof keyboard for absolutely blocking impurities or dust, is an improved Course. [New content] Therefore, the main object of the present invention is to provide a gas guiding groove which can be electrically connected to each other on the second surface of the metal substrate, and a gas guiding hole and a gas guiding groove portion on the second surface It is sealed with a barrier to form a waterproof keyboard that absolutely prevents the ingress of liquids or other impurities. Therefore, the waterproof keyboard of the present invention is characterized in that a flexible circuit board is mounted on a first surface of a metal substrate, and a conductive conductive circuit is formed on the flexible circuit board by printing or the like, and the conductive circuit is provided with a plurality of small distances. The electrical contact group has a button on the electrical contact group that can be pressed to form an electrical contact group, and the bottom edge of the elastic member of each button is adhered to the flexible circuit board to form a barrier to prevent water or The liquid enters a portion of the metal substrate corresponding to each of the contact groups, and an air guiding hole is provided through the center of the contact group for adjusting the movement of the button pressing gas to make the operation smooth, and the metal substrate is away from the second surface of the first surface. The air hole 6 M315399 is provided with air guiding grooves which can be electrically connected to each other, and a blocking member is disposed on the second surface covering all the air guiding holes and the air guiding groove portion for sealing, the gas guiding groove is used for pressing the button, the gas The access control channel makes the operation smooth, and the obstacles prevent the intrusion of liquid or other impurities, hindering the smooth operation or causing the electric contact group to be misdirected or short-circuited. The function of the novel is to provide a waterproof keyboard that can prevent liquid or other impurities from entering the air guiding groove or the inside of the button, keeping the button operation smooth or preventing damage. The above and other technical contents, features and effects of the present invention will be apparent from the following detailed description of the embodiments. 2 is a preferred embodiment of the present invention. The metal substrate 1' has a first surface 1 〇 and a second surface 11 away from the first surface 1 ,.
