Description

Fingerprint recognition switch

The present invention relates to a fingerprint recognition switch, and more particularly to a switch structure for controlling through fingerprint recognition.

The switch is mainly used to control the use of specific equipment or devices. Most of the switches used in the past used the simplest pressing method to achieve the control purpose. However, if the specific equipment or device has concerns about security or confidentiality, special The fingerprint sensor type switch is mainly used to determine whether the user has the authority to control by sensing whether the user's fingerprint is correct or not. However, the current universal fingerprint sensor type switch can only sense a single fingerprint, so it cannot provide multiple uses They are used at the same time. Moreover, the inside is mainly pressed by springs, but the springs will cause elastic fatigue after long-term use, resulting in abnormal conduction conditions. Therefore, these fingerprint sensor switches are long-term for users. The lack of criticism.

Therefore, how to improve the above-mentioned problems is the technical difficulty that the inventor wants to solve.

The main purpose of the present invention is: it is mainly composed of a housing, a movable member, an upper sleeve, an urging member, a conductive silicone rubber and a base, and the user is first sensed by a fingerprint recognition panel on the movable member. The fingerprint is pressed, and the movable part is pressed at the same time so that the urging part presses the conductive silicon rubber, and the conductive silicon rubber contacts the circuit board on the base, thereby achieving the purpose of control.

Switch 1; According to the above, when the finger is placed on the surface of the fingerprint recognition panel 31, the fingerprint recognition panel 31 will first sense the user's fingerprint and send it to the data processing module 7112 of the circuit board 71 for data processing. Module 712 is used to judge the fingerprint. If it is the correct fingerprint, it will be conducted smoothly. If it is not the correct fingerprint, it will not reach the conduction state even if the movable part 3 has been pressed. The data processing module 712 is already in The correct fingerprint data is stored in advance, and multiple sets of fingerprint data can be stored. Therefore, multiple users can be used at the same time. Of course, the fingerprint data can also be changed at any time to adjust the permissions of different users. In addition, through the setting of the data processing module 712, you can also adjust or change the conduction method. In addition to the above, you must sense that the user's fingerprint is correct and press the movable part 3 at the same time to conduct. In addition, you can adjust it to only sense the correct fingerprint. It can be conducted without pressing the movable member 3, or adjusted to only press the movable member 3 and The fingerprint can be turned on by induction, or the fingerprint can be turned on by pressing the movable part 3 for final confirmation before turning on. This way, you can adjust the most suitable use mode according to the use occasion or use needs; In addition to the control of the conduction module 712, the processing module 712 can also number different users according to different fingerprints, thereby outputting signals of different user numbers, so that the fingerprint identification switch 1 can be customized for different users. service. To sum up, compared with the various shortcomings and inconveniences of the conventional fingerprint inductive switch, the fingerprint identification switch 1 of the present invention is designed through the data processing module 712, in addition to making it available for multiple users to use at the same time. In addition, different ways of use can be adjusted to suit different use needs or occasions. Furthermore, through the design of conductive silicone 6, the lack of elastic fatigue in the spring can be avoided.
