Abstract
Description
Technical Field
[0001] The utility model relates to a microswitch with a on-off feedback unit. Background Art
[0002] A microswitch is a small switch, characterized by small size, sensitive action and long service life. They are usually used in occasions that require quick response and high reliability, such as electronic devices, household appliances, industrial control systems, automotive electronics, etc. The microswitch realizes the on-off of the circuit through mechanical action. When an external force acts on the switch, the contacts will contact or separate, thus changing the state of the circuit. However, due to its small size and compact internal structure, it is difficult to add a circuit detection structure to the existing microswitch, and it is impossible to judge and record the on-state of the microswitch. With the advent of the information age, it has become more and more popular to analyze data through big data to formulate better application services. By collecting the on-off information of the microswitch, the usage of each function of the electrical component can be well determined, data analysis can be realized, and data support can be provided for the function development and style design of subsequent products. Content of the Utility Model
[0003] Aiming at the deficiencies of the prior art, the utility model provides a microswitch with a on-off feedback unit, which has a simple structure and a more reasonable layout, can effectively detect and record the dynamics of the microswitch, and has a good use effect.
[0004] To achieve the above object, the utility model provides a microswitch with a on-off feedback unit, which comprises a housing and a base. The housing covers the base. The base is provided with a first pin and a second pin. A contact button is movably arranged on the housing. The first pin extends towards the contact button on the housing to form a connection arm. A contact piece is also arranged in the housing. The contact piece includes a connection part arranged between the first pin and the second pin and a connection part close to the contact button. The connection part is connected to the connection part. The first pin is connected to the connection part through a first resistance element. The second pin is connected to the connection part through a second resistance element. A contact member is connected to the contact button. A first contact arm and a second contact arm for contacting the connection part after the contact button is touched are respectively arranged on both sides of the contact member. The first contact arm is attached to the connection arm. The second contact arm is arranged close to the connection part. A reset spring for resetting the contact button to separate the second contact arm from the contact part is abutted between the housing and the contact member.
[0005] The beneficial effects of such a setting are as follows: With such a setting, when the touch button is not connected, the first contact arm remains in contact with the first pin, and the second contact arm is not in contact with the connection part. At this time, the first pin, the first resistance element, the contact piece connection part, the second resistance element, and the second pin form a complete circuit. At this time, due to the existence of the first resistance element and the second resistance element, the overall resistance is relatively large, and a relatively small electrical signal can be output for the control chip to identify the open state of the switch at this time. When the touch button is connected, the touch button is pressed, causing the second contact arm to contact the connection part. At this time, the first pin, the contact member, the contact piece, the second resistance element, and the second pin form a complete circuit. At this time, since the first resistance element is no longer connected, the resistance on the overall circuit becomes smaller, the output current becomes larger, and the electrical signal is amplified. At this time, the control chip can record the current change, and thus can determine the closed state of the switch by analysis. By recording the change in the current magnitude by the control chip and then through data analysis, the usage information of the switch position function can be obtained, and the user usage situation can be recorded. At the same time, when the switch is not connected, the magnitude of the current passing through is constant. When a short circuit occurs between the first pin and the second pin, the passing current will increase greatly, far greater than the connected state, so it can be judged that a short circuit phenomenon has occurred. And when the current completely disappears, it indicates that an open circuit has occurred at the pin. Thus, when a fault occurs in the switch, a simple fault judgment can be made. The control chip and the analysis system here belong to the prior art and will not be elaborated here. This structure is simple, easy to implement, has good usage effects, and the overall layout is more reasonable, with good usage reliability.
[0006] As a further setting of the present utility model, the first contact arm is arranged as two elastic first clamping arms, and the second contact arm is arranged as two elastic second clamping arms.
[0007] The beneficial effects of such a setting are as follows: With such a setting, the reliability of the contact is ensured, and accidental loosening leading to contact disconnection is avoided. This structure is simple, easy to implement, and has good usage effects.
[0008] As a further setting of the present utility model, the base is further provided with a bracket.

[0009] The beneficial effects of such a setting are as follows: With such a setting, the overall structure is more stable, the installation is reliable, and it is not easy to loosen. At the same time, through the structures of the first exposure window and the second exposure window, it is convenient for structural connection, improving the production and processing efficiency, ensuring the reliability of processing, and the structure is simple and easy to implement.

[0013] The beneficial effects of such arrangement are: such arrangement improves the stability of the structure, facilitates the positioning of the resistor element, ensures the installation in place, ensures the use effect of the structure, and has a good use effect.

The first contact arm 52 is attached to the connecting arm 31. The second contact arm 53 is arranged close to the connecting part 61. A return spring 54 for resetting the touch button 5 to separate the second contact arm 53 from the contact part is abutted between the housing 1 and the contact member 51. The beneficial effect of such a setting is: With such a setting, when the touch button 5 is not connected, the first contact arm 52 remains in contact with the first pin 3, and the second contact arm 53 is not in contact with the connecting part 61. At this time, the first pin 3, the first resistance element 71, the connecting part 62 of the contact piece, the second resistance element 72, and the second pin 4 form a complete circuit.

At this time, the first pin 3, the contact member 51, the contact piece, the second resistance element 72, and the second pin 4 form a complete circuit.

And when the current completely disappears, it indicates that an open circuit has occurred at the pin. Therefore, when a fault occurs in the switch, a simple fault judgment can be made.
