Description

Technical Field

[0001] This utility model relates to the field of switch technology, and in particular to a changeover switch. Background Technology

[0002] As a common electrical component, changeover switches are widely used in various electrical systems to flexibly switch between different circuit states. Traditional changeover switches typically consist of a housing, an operating knob, and an internal switching mechanism. Users connect, disconnect, or switch circuits by rotating or pressing the operating knob. However, with the continuous development of electrical technology and the increasing diversification of application needs, higher requirements have been placed on the functionality and performance of changeover switches. While existing changeover switches meet market demands to some extent, they still have certain limitations. On the one hand, some changeover switches, although designed with both rotary and press operation methods, have overly complex internal structures, making manufacturing difficult and resulting in high production costs. This complexity not only increases the difficulty of the manufacturing process but may also lead to malfunctions during long-term use, affecting the reliability and stability of the equipment. On the other hand, some changeover switches lack operational flexibility; the rotation or pressing of the knob may feel too heavy or stiff, making operation inconvenient for users. Utility Model Content

[0003] In view of this, the purpose of this utility model is to provide a changeover switch that is functionally integrated, easy to operate, highly adaptable and structurally stable.

[0004] To achieve the above objectives, this utility model employs a changeover switch comprising a housing, an operating knob, and a rotating rod connected to the operating knob and extending into the housing. The rotating rod rotates synchronously with the operating knob. The housing includes a rotating assembly, a push-button switch, and a direct-insertion button assembly. The rotating assembly is disposed within the housing and connected to the rotating rod. The push-button switch is confined within the housing and includes a press switch, a movable piece, and several sets of terminals. The press switch faces the rotating assembly and presses against it. The movable piece is disposed inside the push-button switch and is used to change the circuit connection state when pressed. The direct-insertion button assembly is disposed within the housing and includes a direct-insertion button, a clamping spring, and a spring plate. The direct-insertion button is inserted into the housing and is in close contact with the clamping spring through the spring plate. One end of the terminal is connected to the inside of the push-button switch, and the other end extends out of the housing and forms an insertion with the clamping spring of the direct-insertion button assembly.

[0005] The advantages of the above structure are as follows: the synchronous rotation design of the operating knob and lever allows users to easily and quickly control the working state of the changeover switch, improving the convenience and efficiency of operation. The housing integrates a rotating component, a push-button switch, and a plug-in button component, realizing the integration of multiple functions. This allows the changeover switch to have both rotation control and press control functions, meeting more complex application needs. The movable piece design inside the push-button switch can accurately change the circuit connection state when pressed, ensuring the reliability and stability of the circuit connection. At the same time, the plug-in button further enhances the stability and durability of the circuit connection through the tight contact between the spring and the clamping spring, as well as the plug-in design between the terminal and the clamping spring.

[0006] This utility model further configures the push-button switch to be either normally open or normally closed. The internal terminals of the push-button switch include a first set of terminals and a second set of terminals. The first set of terminals corresponds to a normally open push-button switch, and the second set of terminals corresponds to a normally closed push-button switch. The plug-in button assembly matches the terminal configuration inside the corresponding push-button switch. By setting the push-button switch to either normally open or normally closed type, the changeover switch can adapt to more diverse application scenarios. The normally open type is suitable for situations where the circuit needs to be connected when the button is pressed, while the normally closed type is suitable for situations where the circuit needs to be disconnected when the button is pressed. This flexibility greatly improves the versatility and practicality of the changeover switch. The matching of the plug-in button assembly with the terminal configuration inside the corresponding push-button switch ensures that the circuit connection state can be accurately changed when the push-button switch is pressed or released.

[0007] This utility model further configures the push-button switch as a normally open type. The movable piece inside the push-button switch is disconnected from the first set of terminals when not pressed, and forms electrical contact with the first set of terminals when pressed. By using the normally open type of push-button switch, the movable piece is disconnected from the first set of terminals when not pressed, and the circuit is in an open state. This allows the user to intuitively determine whether the circuit is connected by observing the state of the button, thereby improving the safety and reliability of operation.

[0008] This utility model further configures the push-button switch as a normally closed type. The movable piece inside the push-button switch maintains electrical contact with the second set of terminals when not pressed, and disconnects from the second set of terminals when pressed. By ensuring the normally closed push-button switch maintains electrical contact with the second set of terminals when not pressed, the circuit is in a default on-state. This simplifies the operation process in applications requiring continuous power supply or maintaining a certain state, eliminating the need for frequent button presses to keep the circuit connected.

[0009] This utility model is further configured with a housing comprising a bottom socket, a cover plate snapped onto the bottom of the bottom socket, and a panel cover snapped onto the top of the bottom socket, wherein the push-button is inserted into the cover plate. By dividing the housing into multiple components such as the bottom socket, cover plate, and panel cover, and employing snap-fit ​​connections, the assembly process of the entire housing becomes simpler and faster.

[0010] This utility model is further configured with a mounting plate installed on the housing. The mounting plate has a through groove for the rotating rod to pass through, and the rotating rod extends into the housing through the through groove. As part of the housing, the mounting plate provides stable support and guidance for the rotating rod through the through groove, effectively preventing the rotating rod from deviating or wobbling during rotation and enhancing the stability of the entire structure.

[0011] This utility model is further configured such that a switch panel is wrapped around the outer wall of the operating knob, and a switch label is mounted on the switch panel. By mounting the switch label on the switch panel, the function, status, or operating mode of the changeover switch can be clearly identified, helping users to quickly identify and correctly operate the changeover switch, and avoiding safety hazards or equipment damage caused by misoperation.

The direct-insertion button assembly 6 is matched with the corresponding internal terminal 53 of the push-button switch 5 to ensure the accuracy and reliability of the circuit connection. When the push-button switch 5 is normally open, the movable piece 52 is disconnected from the first group of terminals 531 when not pressed, and forms electrical contact with the first group of terminals 531 when pressed. When the push-button switch 5 is normally closed, the movable piece 52 maintains electrical contact with the second group of terminals 532 when not pressed, and disconnects from the second group of terminals 532 when pressed.

[0019] The housing 1 consists of three parts: a bottom socket 11, a cover plate 12, and a front panel cover 13. The cover plate 12 is snapped into the bottom of the bottom socket 11, and the front panel cover 13 is snapped into the top of the bottom socket 11, together forming a sturdy housing for the changeover switch. The push button 61 is inserted into the cover plate 12 for easy pressing operation by the user. In addition, a mounting plate 14 is installed on the housing 1. The mounting plate 14 has a through groove for the rotating rod 3 to pass through. The rotating rod 3 extends into the housing 1 through the through groove and connects with the rotating component 4, realizing a stable connection between the operating knob 2 and the internal mechanism. In order to improve the user experience, the outer walls of the operating knob 2 are covered with a switch panel 21. The switch panel 21 is equipped with a switch label 22, which clearly indicates the function, status, or operation mode of the changeover switch, making it easy for the user to quickly identify and correctly operate the changeover switch.
