Description

Technical Field

[0001] The present application relates to the technical field of electronic equipment, and in particular to an electric switch. Background Art

[0002] An electric switch is an electrical device used to control the on / off state of an electrical circuit. It is widely used in various fields, such as valve control systems, electric vehicle charging ports, and electronic products. An electric switch contains a moving contact and a stationary contact, which are controlled by closing or separating the moving and stationary contacts to control the on / off state of the circuit.

[0003] In the prior art, multiple switches often need to be provided in actual use, which increases the use and production costs. Utility Model Content

[0004] The present application provides an electric switch, which reduces usage and production costs.

[0005] In a first aspect, the present application provides an electric switch comprising: a crank, a drive mechanism, a moving contact assembly, a first static contact, and a second static contact. The crank comprises a rotating end and a swinging end. The rotating end is connected to the drive mechanism, which drives the rotating end to rotate. When the rotating end rotates, the swinging end swings with the rotating end as the swinging center. The moving contact assembly is connected to the swinging end so that the moving contact assembly swings together with the swinging end. The first static contact and the second static contact are respectively arranged on both sides of the moving contact assembly. The moving contact assembly is connected to the first static contact when swinging. Alternatively, the moving contact assembly is connected to the second static contact when swinging. The first static contact is connected to the first output circuit. The second static contact is connected to the second output circuit.

[0006] According to the first aspect, a drive mechanism is connected to the rotating end of the crank, so that the drive mechanism drives the rotating end to rotate and causes the swinging end of the crank to swing. The swinging end drives the movable contact assembly to swing together, and the movable contact assembly swings to different positions to control the connection or disconnection of the first output circuit or the second output circuit of the electric switch. In other words, the operator can simultaneously control the connection and disconnection of multiple circuits in the electric switch using the crank, simplifying the components of the electric switch, reducing the difficulty of operation, and reducing the production cost and operating cost of the electric switch.

[0007] In one possible design, the drive mechanism includes a motor, a reduction assembly, and an output shaft. The motor is used to provide an initial rotational speed. The reduction assembly includes an input shaft and an output shaft, the input shaft being connected to the motor, and the output shaft being connected to the rotating end.

[0008] Based on the description of the above embodiments, by arranging a reduction assembly between the crank and the motor, the initial rotation speed of the motor is reduced, thereby reducing the movement speed of the crank and thereby increasing the service life of the crank.

[0009] In a possible design, a first clamping structure is provided on the output shaft, and a second clamping structure is provided on the rotating end. The first clamping structure and the second clamping structure are clamped and connected to each other so that the rotating end rotates together with the output shaft.

[0010] Based on the description of the above embodiment, a first engaging structure is provided on the output shaft, and a second engaging structure is provided on the rotating end. The first engaging structure and the second engaging structure are engaged and connected, so that the rotating end rotates together with the output shaft, thereby enabling the motor to control the movement of the crank and the moving contact assembly.

[0011] In one possible design, the electric switch may further include a first limiting structure. The first limiting structure is disposed on the motion trajectory of the crank. The first limiting structure includes a first limiting member and a second limiting member, and the first limiting member and the second limiting member are respectively disposed on both sides of the crank.

[0012] Based on the description of the above embodiment, by respectively setting a first limit member and a second limit member on both sides of the crank, the displacement of the crank moving to both sides is limited, thereby controlling the swing amplitude of the crank within a certain range, avoiding occupying more installation space in the electric switch, and further reducing production costs.

[0013] In a possible design, the curvature of the rotating end is greater than the curvature of the swinging end.

[0014] Based on the description of the above embodiment, the curvature of the rotating end is greater than the curvature of the swinging end, which is beneficial to the normal movement of the swinging end and can further reduce the production cost of the electric switch.

[0015] In one possible design, a plurality of grid-like grooves are provided on the crank, and raised rib-like structures are provided between adjacent grooves.

[0016] Based on the description of the above embodiments, providing multiple grid-like grooves on the crank can reduce the material used in crank production. Furthermore, providing raised rib-like structures between adjacent grooves increases the structural strength of the crank, extending its service life and further reducing production costs.

[0017] In a possible design, the electric switch may further include a first mounting groove and a second mounting groove, wherein the first mounting groove is used to mount and fix the first static contact, and the second mounting groove is used to mount and fix the second static contact.

[0018] Based on the description of the above embodiment, a first mounting groove and a second mounting groove are designed in the electric switch. The first mounting groove is used to install and fix the first static contact, and the second mounting groove is used to install and fix the second static contact, thereby improving the reliability of the electric switch.

[0019] In a possible design, the electric switch may further include a first micro switch and a second micro switch. The first micro switch is used to control the motor to rotate forward, and the second micro switch is used to control the motor to rotate reversely.

[0020] Based on the description of the above embodiments, setting a first micro switch and a second micro switch in the electric switch can automatically control the moving contact assembly to move toward the first static contact and connect with the first static contact, or automatically control the moving contact assembly to move toward the second static contact and connect with the second static contact.

[0021] In one possible design, a first button is provided on the first microswitch, a second button is provided on the second microswitch, and the first and second microswitch are respectively disposed on opposite sides of the crank, such that the first and second buttons are both disposed on the swinging track of the swinging end.

[0022] Based on the description of the above embodiment, the first microswitch and the second microswitch are respectively arranged on both sides of the crank, so that the first button and the second button are both arranged on the swinging track of the swinging end, so that the motor cannot rotate forward and reverse at the same time, avoiding the problem of the motor getting stuck.

[0023] In one possible design, the electric switch may further include an operating structure connected to the output shaft so that the operating structure, the output shaft, and the rotating end rotate coaxially. A portion of the operating structure is exposed outside the electric switch.

[0024] Based on the description of the above embodiments, an operating structure is provided in the electric switch to manually control the moving contact assembly to move toward the first static contact and connect with the first static contact, or automatically control the moving contact assembly to move toward the second static contact and connect with the second static contact.

[0041] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0042] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this application belongs; the terms used in the specification of the application herein are only for the purpose of describing specific embodiments and are not intended to limit this application.

[0043] The terms "comprises", "comprising" and "having" and any variations thereof in the specification, claims and drawings of this application are intended to cover but not exclude other contents. The word "a" or "an" does not exclude the presence of a plurality.

[0044] References to "embodiments" herein mean that a particular feature, structure, or characteristic described in connection with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase "embodiment" in various places in the specification does not necessarily refer to the same embodiment, nor does it necessarily refer to independent or alternative embodiments that are mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0045] The term "and / or" in this document simply describes a relationship between related objects, indicating that three possible relationships exist. For example, "A and / or B" can mean: A exists alone, A and B exist simultaneously, or B exists alone. Additionally, the character " / " in this document generally indicates that the related objects are in an "or" relationship.

[0046] The directional words appearing in the following description are all directions shown in the drawings and do not limit the specific structure of this application. For example, in the description of this application, the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc., which indicate directions or positional relationships, are based on the directions or positional relationships shown in the drawings and are only for the convenience of describing this application and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operate in a specific direction, and therefore should not be understood as limiting this application.

[0047] In addition, the expressions indicating directions such as the X direction, Y direction, and Z direction used to illustrate the operation and construction of the various components of this embodiment are not absolute but relative, and although these indications are appropriate when the various components are in the positions shown in the figures, when these positions are changed, these directions should be interpreted differently to correspond to the changes.

[0048] In addition, the terms "first", "second", etc. in the description and claims of this application or the above-mentioned drawings are used to distinguish different objects, rather than to describe a specific order, and may explicitly or implicitly include one or more such features.

It can also refer to internal communication between two elements. A signal connection can refer to a signal connection through a circuit or a signal connection through a media medium, such as radio waves. Those skilled in the art will understand the specific meanings of the above terms in this application.

[0051] like Figure 1 and Figure 2 As shown, the first aspect of the present application provides an electric switch 100, which includes: a crank 1, a drive mechanism 2, a moving contact assembly 3, a first static contact 4, and a second static contact 5. The crank 1 includes a rotating end 1a and a swinging end 1b. The rotating end 1a is connected to the drive mechanism 2, which drives the rotating end 1a to rotate. When the rotating end 1a rotates, the swinging end 1b swings with the rotating end 1a as the swing center. The moving contact assembly 3 is connected to the swinging end 1b, so that the moving contact assembly 3 swings together with the swinging end 1b. The first static contact 4 and the second static contact 5 are respectively arranged on either side of the moving contact assembly 3. When the moving contact assembly 3 swings, it connects with the first static contact 4. Alternatively, when the moving contact assembly 3 swings, it connects with the second static contact 5. The first static contact 4 is connected to the first output circuit. The second static contact 5 is connected to the second output circuit.

[0052] The drive mechanism 2 is the component within the electric switch 100 that provides power and movement. It converts electrical energy, fuel energy, and other energy into mechanical energy to drive the other components within the electric switch 100. For example, the drive mechanism 2 is connected to the rotating end 1a of the crank 1, causing the crank 1a to rotate.

[0053] Crank 1 is a transmission structure within electric switch 100, typically used to convert rotational motion into reciprocating motion. Specifically, crank 1 may include a rotating end 1a and a swinging end 1b. Rotating end 1a rotates, while swinging end 1b reciprocates. The reciprocating motion may be oscillating.

[0054] The moving contact assembly 3 is connected to the swing end 1b, causing the moving contact assembly 3 to swing together with the swing end 1b. The first static contact 4 and the second static contact 5 are respectively arranged on either side of the moving contact assembly 3, so that the contact assembly is connected to the first static contact 4 during swinging. Alternatively, the contact assembly is connected to the second static contact 5 during swinging.

[0055] Specifically, the movable contact assembly 3 reciprocates between the first stationary contact 4 and the second stationary contact 5. When the movable contact assembly 3 moves toward the first stationary contact 4, the movable contact assembly 3 can connect with the first stationary contact 4. When the movable contact assembly 3 moves toward the second stationary contact 5, the movable contact assembly 3 can connect with the second stationary contact 5.

[0056] The first static contact 4 is connected to the first output line, so that the electric switch 100 is connected to the external circuit through the first output line.

[0057] The second static contact 5 is connected to the second output line, so that the electric switch 100 is connected to the external circuit through the second output line.

[0058] When the moving contact assembly 3 is connected to the first static contact 4, the first output line is connected. Conversely, when the moving contact assembly 3 is not connected to the first static contact 4, the first output line is disconnected.

[0059] Similarly, when the moving contact assembly 3 is connected to the second static contact 5, the second output line is connected. Conversely, when the moving contact assembly 3 is not connected to the second static contact 5, the second output line is disconnected.

[0060] In summary, the drive mechanism 2 is connected to the rotating end 1a of the crank 1, so that the drive mechanism 2 drives the rotating end 1a to rotate and causes the swinging end 1b of the crank 1 to swing. The swinging end 1b drives the movable contact assembly 3 to swing together. The movable contact assembly 3 swings to different positions to control the connection or disconnection of the first output circuit or the second output circuit of the electric switch 100. In other words, the operator can simultaneously control the connection and disconnection of multiple circuits in the electric switch 100 using the crank 1, simplifying the components of the electric switch 100, reducing the difficulty of operation, and simultaneously reducing the production and operating costs of the electric switch 100.

[0061] like Figure 3 As shown, in some embodiments, the drive mechanism 2 includes a motor 21, a reduction assembly, and an output shaft 22. The motor 21 is used to provide an initial rotational speed. The reduction assembly includes an input shaft and an output shaft 22, the input shaft being connected to the motor 21, and the output shaft 22 being connected to the rotating end 1a.

[0062] The motor 21 is a device that converts electrical energy into mechanical energy. The motor 21 generates torque and rotational motion through the interaction of currents in a magnetic field.

[0063] The reduction assembly is used to reduce the output speed of the motor 21. The reduction assembly may include an input shaft and an output shaft 22. The input shaft is connected to the motor 21 and is used to transmit the initial speed of the motor 21 to the reduction assembly. The output shaft 22 is connected to the crank 1 and is used to transmit the final speed to the crank 1. The final speed is lower than the initial speed.

[0064] Specifically, the reduction assembly generally reduces speed by one or more meshing gear sets. When the high-speed rotation of the motor 21 passes through the reduction assembly, the initial speed of the motor 21 output is reduced by adjusting the gear ratios of the gears in the gear set.

[0065] According to the description of the above embodiment, by arranging a reduction assembly between the crank 1 and the motor 21, the initial rotation speed of the motor 21 is reduced, thereby reducing the movement speed of the crank 1 and thereby increasing the service life of the crank 1.

[0066] Further, if Figure 3 and Figure 4 As shown, in some embodiments, the output shaft 22 is provided with a first clamping structure 23, and the rotating end 1a is provided with a second clamping structure 11. The first clamping structure 23 is clamped and connected with the second clamping structure 11, so that the rotating end 1a rotates with the output shaft 22.

[0067] The first engaging structure 23 can be a engaging groove or an engaging block. Similarly, the second engaging structure 11 can be a engaging groove or an engaging block. The engaging block is engaged in the engaging groove, so that the linkage structure can rotate together with the crank 1.

[0068] The first engaging structure 23 is a engaging groove, and the second engaging structure 11 is a engaging block. Alternatively, the first engaging structure 23 is a engaging block, and the second engaging structure 11 is a engaging groove. The engaging surfaces of the engaging groove and the engaging block have the same shape. For example, the engaging surface can be rectangular, star-shaped, or the like.

[0069] According to the description of the above embodiment, the output shaft 22 is provided with a first engaging structure 23, and the rotating end 1a is provided with a second engaging structure 11. The first engaging structure 23 is engaged with the second engaging structure 11, so that the rotating end 1a rotates with the output shaft 22, thereby enabling the motor 21 to control the movement of the crank 1 and the moving contact assembly 3.

[0070] Furthermore, when the amplitude of the crank 1 movement in the electric switch 100 is too large, it will occupy more installation space in the electric switch 100. In order to save the installation space in the electric switch 100, the present application has made the following design. Figure 2 and Figure 5 Provide a detailed description.

[0071] The electric switch 100 provided in the embodiment of the present application may further include a first limiting structure. The first limiting structure is arranged on the motion trajectory of the crank 1. The first limiting structure includes a first limiting member 14 and a second limiting member 15, which are respectively arranged on both sides of the crank 1.

[0072] When the crank 1 moves toward the first limiter 14 and reaches the position where the first limiter 14 is set, the first limiter 14 abuts against the crank 1, limiting the crank 1 from continuing to move in that direction. Similarly, when the crank 1 moves toward the second limiter 15 and reaches the position where the second limiter 15 is set, the second limiter 15 abuts against the crank 1, limiting the crank 1 from continuing to move in that direction.

[0073] In order to further save material and production costs, the first limiter 14 and the second limiter 15 can be made of components that already exist in the electric switch 100. Figure 5 As shown, the first limiting member 14 and the second limiting member 15 can be positioning pins in the electric switch 100. Two of the positioning pins are arranged on the motion trajectory of the crank 1, so that the positioning pins can not only fix the crank 1 but also limit the crank 1, thereby further reducing production costs.

[0074] According to the description of the above embodiment, by respectively arranging a first limit member 14 and a second limit member 15 on both sides of the crank 1, the displacement of the crank 1 moving to both sides is limited, thereby controlling the swing amplitude of the crank 1 within a certain range, avoiding occupying more installation space in the electric switch 100, and further reducing the production cost.

[0075] In some embodiments, the curvature of the rotating end 1 a is greater than the curvature of the swinging end 1 b .

[0076] Curvature is a quantity that describes the degree of curvature of a geometric shape. Specifically, in a graph, a large curvature means that the curve bends very sharply at a certain point, and the local shape of the curve at that point is close to a circle with a small radius. In contrast, a small curvature means that the curve bends more gently at that point, and the local shape of the curve at that point is close to a circle with a large radius or close to a straight line. Such points are often called "smooth" points.

[0077] The greater the curvature of the rotating end 1a, the smaller the curve radius of the rotating end 1a. The smaller the curvature of the swinging end 1b, the larger the curve radius of the swinging end 1b. The larger the curve radius of the rotating end 1a, the more revolutions the rotating end 1a can make at the same speed of the motor 21. The smaller the curve radius of the swinging end 1b, the shorter the path of movement for the same number of revolutions of the rotating end 1a.

[0078] Moreover, the rotation of the rotating end 1a can provide kinetic energy for the reciprocating motion of the swing end 1b. The more turns the rotating end 1a rotates, the greater the kinetic energy provided, which is beneficial to the normal motion of the swing end 1b.

[0079] The smaller the curve radius of the swing end 1 b is, the shorter the movement path is, and the less installation space is occupied in the electric switch 100 , thereby further reducing the production cost of the electric switch 100 .

[0080] In summary, the curvature of the rotating end 1 a is greater than the curvature of the swing end 1 b , which is beneficial to the normal movement of the swing end 1 b and can further reduce the production cost of the electric switch 100 .

[0081] In some embodiments, as Figure 4 As shown, the crank 1 is provided with a plurality of grid-like grooves 12 , and a raised rib-like structure 13 is provided between adjacent grooves 12 .

[0082] According to the description of the above embodiment, the multiple grid-like grooves 12 provided on the crank 1 can reduce the material used in the production of the crank 1. At the same time, the raised rib-like structures 13 provided between adjacent grooves 12 are used to increase the structural strength of the crank 1 and extend the service life of the crank 1, thereby further reducing production costs.

[0083] Furthermore, the electric switch 100 has many internal components and the assembly process is complicated. Therefore, the electric switch 100 is prone to assembly errors during the assembly process, resulting in the misalignment of some components, which in turn affects the reliability of the electric switch 100. In order to solve the above problems, the present application has made the following designs:

[0084] In some embodiments, the electric switch 100 may further include a first mounting groove 41 and a second mounting groove 51. The first mounting groove 41 is used to mount and fix the first static contact 4. The second mounting groove 51 is used to mount and fix the second static contact 5.

[0085] like Figure 6 As shown, the first mounting groove 41 can guide the first static contact 4 during installation, reducing the difficulty of installing the first static contact 4. The first mounting groove 41 can also limit the first static contact 4 during installation, thereby reducing the probability of the first static contact 4 being misaligned or falling when the electric switch 100 is bumped or shaken, thereby improving the reliability of the electric switch 100.

[0086] Similarly, if Figure 6As shown, the second mounting groove 51 can guide the second static contact 5 during installation, reducing the difficulty of installing the second static contact 5. The second mounting groove 51 can also limit the second static contact 5 during installation, thereby reducing the probability of the second static contact 5 being misaligned or falling when the electric switch 100 is bumped or shaken, thereby improving the reliability of the electric switch 100.

[0087] In summary, the first mounting groove 41 and the second mounting groove 51 are designed in the electric switch 100. The first mounting groove 41 is used to install and fix the first static contact 4, and the second mounting groove 51 is used to install and fix the second static contact 5, thereby improving the reliability of the electric switch 100.

[0088] Furthermore, the electric switch 100 has two current output terminals, the first static contact 4 and the second static contact 5. In order to be able to arbitrarily select the first static contact 4 or the second static contact 5 as the current output terminal according to actual needs, the electric switch 100 in this application can be provided with the following two control systems:

[0089] Control structure 1, automatic control system. Among them, such as Figure 2 As shown, the automatic control system may include a first micro switch 6 and a second micro switch 7. The first micro switch 6 is used to control the motor 21 to rotate forward, and the second micro switch 7 is used to control the motor 21 to rotate reverse.

[0090] The first microswitch 6 and the second microswitch 7 are both electrically connected to the motor 21 and the control center. The electrical signals sent by the control center can remotely control the first microswitch 6 and the second microswitch 7. The first microswitch 6 and the second microswitch 7 can automatically control the rotation of the motor 21, thereby controlling the movement of the movable contact assembly 3.

[0091] The motor 21 can rotate in two directions: forward and reverse. When the motor 21 rotates forward, the swing end 1b of the crank 1 and the moving contact assembly 3 move in a first direction X. When the motor 21 rotates reversely, the swing end 1b of the crank 1 and the moving contact assembly 3 move in a direction opposite to the first direction X. The first direction X can be the direction in which the moving contact assembly 3 moves toward the first stationary contact 4. The direction opposite to the first direction X can be the direction in which the moving contact moves toward the second stationary contact 5.

[0092] To sum up, setting the first microswitch 6 and the second microswitch 7 in the electric switch 100 can automatically control the moving contact assembly 3 to move toward the first static contact 4 and connect with the first static contact 4, or automatically control the moving contact assembly 3 to move toward the second static contact 5 and connect with the second static contact 5.

[0093] Furthermore, considering that the motor 21 cannot rotate forward and reverse at the same time, the following design is also made in this application:

[0094] In some embodiments, as Figure 2 and Figure 7 As shown, the first micro switch 6 is provided with a first button 61. The second micro switch 7 is provided with a second button. The first micro switch 6 and the second micro switch 7 are respectively arranged on both sides of the crank 1, so that the first button 61 and the second button are both arranged on the swing track of the swing end 1b.

[0095] The first button 61 is used to control the electrical connection between the first microswitch 6 and the motor 21. When the first button 61 is pressed, the electrical connection between the first microswitch 6 and the motor 21 is established, and the first microswitch 6 can control the motor 21 to rotate forward. Conversely, when the first button 61 is not pressed, the electrical connection between the first microswitch 6 and the motor 21 is disconnected, and the first microswitch 6 cannot control the motor 21 to rotate forward.

[0096] Similarly, the second button is used to control the electrical connection between the second microswitch 7 and the motor 21. When the second button is pressed, the electrical connection between the second microswitch 7 and the motor 21 is established, and the second microswitch 7 can control the motor 21 to reverse. Conversely, when the second button is not pressed, the electrical connection between the second microswitch 7 and the motor 21 is disconnected, and the second microswitch 7 cannot control the motor 21 to reverse.

[0097] The first microswitch 6 and the second microswitch 7 are respectively arranged on either side of the crank 1, so that the first button 61 and the second button are both located on the swinging trajectory of the swinging end 1b. When the swinging end 1b rotates toward the first microswitch 6 and abuts against the first button 61, the abutting force between the swinging end 1b and the first button 61 can be used to press the first button 61. When the swinging end 1b rotates toward the second microswitch 7 and abuts against the second button, the abutting force between the swinging end 1b and the second button can be used to press the second button.

[0098] Obviously, when the swing end 1b abuts against the first button 61, it cannot abut against the second button, so the first button 61 and the second button cannot be pressed at the same time, that is, the first micro switch 6 and the second micro switch 7 cannot be connected to the motor 21 at the same time, preventing the motor 21 from rotating forward and reverse at the same time.

[0099] To sum up, the first microswitch 6 and the second microswitch 7 are respectively arranged on both sides of the crank 1, so that the first button 61 and the second button are both arranged on the swing track of the swing end 1b, so that the motor 21 cannot rotate forward and reverse at the same time, avoiding the problem of the motor 21 getting stuck.

[0100] Control structure 2: manual control system. Figure 2 As shown, the manual control system may include an operating structure 8. The operating structure 8 is connected to the output shaft 22 so that the operating structure 8, the output shaft 22 and the rotating end 1a rotate coaxially. A portion of the operating structure 8 is exposed outside the electric switch 100.

[0101] The operating structure 8 is connected to the output shaft 22, so that the operating structure 8, the output shaft 22, and the rotating end 1a rotate coaxially. Thus, the movement of the movable contact assembly 3 can be controlled by controlling the rotation of the operating structure 8. Specifically, when the operating structure 8 rotates clockwise, the movable contact assembly 3 moves toward the first stationary contact 4 and connects with the first stationary contact 4. When the operating structure 8 rotates counterclockwise, the movable contact assembly 3 moves toward the second stationary contact 5 and connects with the second stationary contact 5.

[0102] In addition, a through hole is provided on the housing of the electric switch 100 , and the operating structure 8 is sleeved in the through hole, so that a portion of the operating structure 8 is exposed outside the electric switch 100 , thereby facilitating the operator to manually control the operating structure 8 to rotate.

[0103] In summary, setting the operating structure 8 in the electric switch 100 can manually control the moving contact assembly 3 to move toward the first static contact 4 and connect with the first static contact 4, or automatically control the moving contact assembly 3 to move toward the second static contact 5 and connect with the second static contact 5.

[0104] Furthermore, the portion of the operating structure 8 exposed outside the electric switch 100 may include but is not limited to the following two structures: For ease of understanding, the first portion is used below to refer to the portion of the operating structure 8 exposed outside the electric switch 100.

[0105] In the first structure, the first part may be a handle provided outside the protective cover. The operator rotates the handle to control the movement of the movable contact assembly 3.

[0106] In the second structure, the first part may be a hexagonal socket provided outside the protective cover. The operator rotates the hexagonal socket with a tool adapted to the hexagonal socket, thereby controlling the movement of the moving contact assembly 3 .
