In order to highlight the technological feel and user experience of electronic products, many electronic products use touch to trigger a series of switches. Currently, the touch switches of electronic products usually only have two modes: on and off. Therefore, in actual use, the functional modes are limited and the applicability is not strong. Utility Model Content

[0003] To overcome the above-mentioned shortcomings, the purpose of this utility model is to provide a touch sensing switch device. By utilizing the input levels of the third and fourth pins, the operating modes of the first chip are divided into four, which increases the application scenarios of the touch sensing switch device and facilitates the switching of the touch switch between different operating modes according to different application scenarios, thereby improving the applicability of the touch sensing switch device.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is: a touch-sensitive switch device, comprising:

The first chip includes a first pin, a second pin, a third pin, and a fourth pin. The sensor is connected to the first pin. The third pin is connected to a power supply through the first switch, and the fourth pin is connected to a power supply through the second switch.

[0006] The control circuit includes a second chip connected to the touch circuit and the second chip being connected to the second pin of the first chip.

[0007] In this technical solution, the touch circuit is used to detect whether there is a touch action, and sends a signal to the second chip according to the touch action and the state of the third and fourth pins, so that the second chip can control the corresponding functions. By adding two additional pins to control the working mode of the first chip on the basis of touch, the application scenarios of the touch sensing switch device are increased, thereby improving the applicability of the touch sensing switch device.

[0008] In some implementations, the touch circuit further includes a first resistor, through which the sensor is connected to the first chip.

[0009] In this technical solution, the first resistor is used to improve the anti-interference capability of the touch circuit.

[0010] In some implementations, the touch circuit further includes a first capacitor connected in parallel with the sensor, and the first capacitor is connected to the first pin.

[0012] In some implementations, the first chip includes a first synchronous output mode, in which the second pin is input to a low level and the third pin is input to a low level.

[0013] In this technical solution, the first synchronous output mode outputs a low level to the second chip when there is no touch, and outputs a high level to the second chip when there is a touch. After the touch is released, the first chip resumes outputting a low level to the second chip, thus adding a working mode to the first chip.

[0014] In some implementations, the first chip includes a second synchronous output mode, in which the second pin is input to a low level and the third pin is input to a high level.

[0015] In this technical solution, the second synchronous output mode outputs a high level to the second chip when there is no touch, and outputs a low level to the second chip when there is a touch. After the touch is released, the first chip resumes outputting a high level to the second chip, thus adding a working mode to the first chip.

[0016] In some implementations, the first chip includes a first level-holding mode, in which the second pin receives a high level and the third pin receives a low level.

[0017] In this technical solution, the first level holding mode outputs a low level to the second chip when there is a five-touch event, outputs a high level to the second chip during touch, and maintains a high level signal to the second chip when the touch is released, thus adding a working mode to the first chip.

[0018] In some implementations, the first chip includes a second level-holding mode, in which the second pin is input to a high level and the third pin is input to a high level.

[0019] In this technical solution, the second level holding mode is that when there is a touch, the first chip outputs a high level to the second chip, when there is a touch, the first chip outputs a low level to the second chip, and when the touch is released, the first chip maintains the output of a low level signal to the second chip, thus adding a working mode to the first chip.

[0020] In some embodiments, the touch-sensitive switch device further includes a load connected to the second chip.

[0021] In this technical solution, the load is used to implement the corresponding function, and the second chip is connected to the load, which is beneficial to use the second chip to control the operation of the load.

[0022] In some embodiments, the control circuit further includes an LED light connected to the second chip.

[0023] In this technical solution, LED lights are used to display the load level, making it easier for operators to obtain the current load level.

[0024] The beneficial effect of this utility model is that by utilizing the input levels of the third and fourth pins, the operating modes of the first chip are divided into four, which increases the application scenarios of the touch sensing switch device and facilitates the touch switch to switch operating modes according to different application scenarios, thereby improving the applicability of the touch sensing switch device.
