Detailed Description

In order to make the technical solutions and advantages of the present invention clearer, the following will describe embodiments of the present invention in further detail with reference to the accompanying drawings.

In the embodiment of the invention, the direction of the panel of the midway switch is defined as the top direction or the upper direction, and conversely, the direction of the mounting seat of the midway switch is defined as the bottom direction or the lower direction. The panel of the halfway-pulling switch refers to the surface of the shell facing the user in the working state. For example, a surface of the rocker facing the panel of the halfway-pulling switch is referred to as a top surface or an upper surface, and a surface of the rocker facing the fixed frame is referred to as a bottom surface or a lower surface, with an assembled state of the rocker in the halfway-pulling switch as a reference.

In the related art, as shown in fig. 1, a one-bit halfway toggle switch includes: a first paddle 101 having two movable contacts 100, a second paddle 102 having two movable contacts 100, a first outlet terminal assembly 201 having two stationary contacts 200, a second outlet terminal assembly 202 having two stationary contacts 200, a first inlet terminal assembly 203 and a second inlet terminal assembly 204. Wherein one side of the first inlet terminal assembly 203 is connected to the first rocker 101, one side of the second inlet terminal assembly 204 is connected to the second rocker 102, and the first inlet terminal assembly 203, the first rocker 101, the second rocker 102 and the second inlet terminal assembly 204 are arranged side by side along the width direction of the rocker. One of the two stationary contacts 200 of the first outlet terminal assembly 201 is located below the movable contact 100 at the first end of the first rocker 101, and the other is located below the movable contact 100 at the second end of the second rocker 102; one of the two stationary contacts 200 of the second outlet terminal assembly 202 is located below the movable contact 100 at the second end of the first rocker 101 and the other is located below the movable contact 100 at the first end of the second rocker 102; wherein, first end and second end are the both ends along wane length direction.

In this type of midway switch, the first incoming terminal assembly 203, the first rocker 101, the second rocker 102 and the second incoming terminal assembly 204 are distributed in sequence along the width direction of the rocker, so that the volume of the midway switch is large, which further causes the following technical problems:

(1) the internal redundant space of the midway tripping switch is more, which is not beneficial to the miniaturization development of the midway tripping switch.

(2) The overall width of the midway switch is wide, so that two one-position midway switches cannot be arranged side by side to form a two-position midway switch, and the function of the two-position midway switch can be realized only by means of a functional piece of the four-position midway switch and an external jumper wire, so that the space of a backseat of the two-position midway switch is increased, the structure is complex, the assembly and installation processes are complex, and the cost is high.

In combination with the structure of the half-way toggle switch provided by the above-mentioned related art, the following is an exemplary description of the working principle of the one-position half-toggle switch in the control of the electric appliance (wherein, the on-off control principle of the one-position half-toggle switch and the multi-position half-toggle switch to the circuit is the same):

the midway trigger switch is arranged between the two double-control switches, so that the on-off of one electric appliance can be controlled at three positions, wherein the connection relation and the working principle between the midway trigger switch and the double-control switches can be seen in figure 2:

as shown in fig. 2, the wire inlet terminals of the double control switch a and the double control switch C are respectively marked as M, the two wire outlet terminals of the double control switch a and the double control switch C are respectively marked as M1 and M2, the two wire inlet terminals of the midway trigger switch are respectively marked as L1 and L2, and the four wire outlet terminals are respectively marked as L11, L12, L21, and L22, wherein the wire inlet terminal L1 belongs to the first wire inlet terminal assembly, the wire inlet terminal L2 belongs to the second wire inlet terminal assembly, the wire outlet terminals L11 and L12 belong to the first wire outlet terminal assembly, and the wire outlet terminals L21 and L22 belong to the second wire outlet terminal assembly.

The midway trigger switch has two control states: (1) inlet terminal L1 is connected to outlet terminal L11, and inlet terminal L2 is connected to outlet terminal L21 (see fig. 2);

(2) line terminal L1 is connected to line terminal L12, and line terminal L2 is connected to line terminal L22 (not shown).

In the state of fig. 2, the on-state of the double-control switch a, the off-state of the half-trip switch B, and the on-state of the double-control switch C are switched (that is, switched to a state different from the state of fig. 2) based on the on-state, and the on-state of the double-control switch a, the off-state of the half-trip switch B, and the off-state of the double-control switch C are switched. The double-control switch A, the midway trigger switch B and the double-control switch C respectively correspond to three positions, namely, the on-off control of the electric appliance can be realized at any one of the three positions.

According to an aspect of an embodiment of the present invention, there is provided a seesaw, as shown in fig. 3, the seesaw including: a support 11, a first abutting portion 12, a second abutting portion 13, an arm portion 14, a first movable contact 15, and a second movable contact 16. Wherein the first abutting portion 12 and the second abutting portion 13 are respectively connected with two opposite sides of the supporting portion 11; the arm portion 14 is connected to a side of the first abutting portion 12 or the second abutting portion 13 away from the support portion 11; the first movable contact 15 is located on the bottom surface of the arm portion 14, and the second movable contact 16 is located on the top surface of the arm portion 14.

In the embodiment of the present invention, the rocker can be used for a switch, such as a half-stop switch, for example, when the rocker is used for a half-stop switch, the top surface of the arm 14 referred to above is a surface of the arm 14 facing a panel of the half-stop switch, and accordingly, the bottom surface of the arm 14 is a surface opposite to the top surface of the arm 14.

In this rocker, the arm 14 is connected to one of the first abutting portion 12 and the second abutting portion 13, for example, as shown in fig. 3, the arm 14 is connected to a side of the second abutting portion 13 away from the supporting portion 11, or the arm 14 is connected to a side of the first abutting portion 12 away from the supporting portion 11.

Illustratively, the first movable contact 15 is located on the bottom surface of the arm portion 14 at a position close to the free end of the arm portion, and the second movable contact 16 is located on the top surface of the arm portion 14 at a position close to the free end of the arm portion (the above-mentioned free end is the end of the arm portion 14 away from the abutting portion connected thereto).

In some possible implementations, as shown in fig. 3, the central axes of the first movable contact 15 and the second movable contact 16 are coincident, that is, the first movable contact 15 and the second movable contact 16 are oppositely disposed. By the arrangement, the structure of the midway trigger switch is simplified, and the preparation process of the rocker is simplified.

For example, the arm portion 14 has a fitting through-hole penetrating through its top and bottom surfaces, and a link is provided so as to penetrate through the fitting through-hole, the bottom end of the link being connected to the first movable contact 15, and the top end of the link being connected to the second movable contact 16.

The link may be independent from each of the first and second

movable contacts

15 and 16, and the connection manner of the link to the first and second

movable contacts

15 and 16 includes, but is not limited to, the following: welding, threaded connection, splicing and the like. One end of the connecting rod may be integrally formed with one of the first movable contact 15 and the second movable contact 16 so that the other end of the connecting rod is connected with the corresponding movable contact after the connecting rod passes through the fitting through-hole.

In the case of the conventional seesaw, as shown in fig. 1, it generally has two arm portions connected to a corresponding abutting portion, and each arm portion has one movable contact, that is, the two movable contacts are symmetrically located at both sides of the supporting portion 11 of the seesaw.

The seesaw provided by the embodiment of the present invention is different from the conventional seesaw in at least the following points: there is only one arm 14 and the arm 14 carries both the first movable contact 15 and the second movable contact 16, i.e. the first movable contact 15 and the second movable contact 16 are only on one side of the support 11 of the rocker, the first movable contact 15 and the second movable contact 16 are in contact with the stationary contacts in different outlet terminal assemblies respectively.

With such a configuration, when the rocker provided by the embodiment of the present invention is used in a middle-pulling switch, referring to fig. 4, two rockers (referred to as the first rocker 101 and the second rocker 102, respectively) can be arranged side by side, and accordingly, the positions of two outlet terminal assemblies (referred to as the first outlet terminal assembly 201 and the second outlet terminal assembly 202, respectively, which run along the dashed lines in fig. 4) are adaptively designed, so that the first outlet terminal assembly 201 and the second outlet terminal assembly 202 are located on the same side as the arm 14 of the rocker. Thus, the first movable contact 15 of the first rocker 101 is adapted to contact the first stationary contact 22 of the first outlet terminal assembly 201, and the second movable contact 16 of the second rocker 102 is adapted to contact the second stationary contact 23 of the first outlet terminal assembly 201. The first movable contact 15 of the second rocker 102 is used for contacting with the first fixed contact 22 of the second outlet terminal assembly 202, and the second movable contact 16 of the first rocker 101 is used for contacting with the second fixed contact 23 of the second outlet terminal assembly 202, so that the two-way reversing function of the midway trigger switch can be realized.

Based on the structure of the rocker according to the embodiment of the present invention, the first and second

outlet terminal assemblies

201 and 202 can be located on the same side as the arm 14 of the rocker, that is, the first and second

outlet terminal assemblies

201 and 202 no longer occupy the space on both sides of the rocker in the length direction thereof, but only occupy the space on one side of the rocker in the length direction, so that the space on the other side of the rocker opposite to the occupied side is empty. In this way the first and second

inlet terminal assemblies

301, 302 can be adapted such that they are located at the empty space of the rocker along the other side of the rocker in its length direction. That is to say, the incoming line terminal subassembly and the terminal subassembly of being qualified for the next round of competitions have only taken the space of the wane both sides that distribute along wane length direction, and the space of the wane both sides that distribute along wane width direction has avoided taking up, and this is favorable to showing the width that reduces the switch of pulling midway, and then reduces the volume of pulling the switch midway.

In addition, although the first movable contact 15 and the second movable contact 16 are respectively located on the bottom surface and the top surface of the arm portion 14 of the rocker, so that the first outgoing terminal assembly 201 and the second outgoing terminal assembly 202 occupy more spaces on both sides of the rocker distributed in the thickness direction of the rocker, i.e., more spaces in the up-down direction, for the midway-pulling switch, the spaces in the up-down direction are generally more redundant and have larger latitude.

In summary, the seesaw provided by the embodiment of the invention is beneficial to reducing the width of the midway trigger switch, so that the midway trigger switch is more compact and miniaturized. Thus, referring to fig. 5, when the two-position midway switch is prepared, two one-position midway switches can be arranged side by side along the width direction of the two-position midway switch, which is beneficial to reducing the volume of the two-position midway switch, and the one-position midway switch and the two-position midway switch can share functional components, thereby improving the universality of the functional components of the midway switch, avoiding additional wiring when the two-position midway switch is formed, simplifying the structure and the assembly process, reducing the cost and prolonging the service life.

In addition, as for the structures of the supporting portion 11, the first abutting portion 12, the second abutting portion 13 and the arm portion 14 included in the seesaw, these may adopt some structures commonly used in the art, and the embodiments of the present invention do not specifically limit the structures.

For example, as shown in fig. 3, the supporting portion 11 of the rocker includes: a support body 111 and two assembling sections 112, the two assembling sections 112 being respectively located at both sides of the support body 111 distributed in a width direction thereof. The support body 111 is, for example, a flat plate, and both sides of the support body 111 distributed along the longitudinal direction thereof are connected to the first abutting portion 12 and the second abutting portion 13, respectively. The assembling sections 112 have a receiving space for receiving a supporting member of the middle trigger switch, the receiving space is, for example, arc, trapezoid, rectangle, triangle, etc., the top of the supporting member extends into the receiving space and abuts against the top of the receiving space in an overlapping manner, so that the two assembling sections can rotate around the top of the supporting member, and the swing of the rocker is realized.

The first and second abutting

portions

12 and 13 of the rocker are symmetrically located on both sides of the supporting portion 11, for example, the first and second abutting

portions

12 and 13 may each comprise a plate-shaped abutting body, which may be, for example, rectangular, isosceles trapezoid, etc., and further, the first and second abutting

portions

12 and 13 may further comprise abutting bosses located on the surface of the plate-shaped abutting body.

The first abutment 12 serves to deliver the arm portion 14 to an appropriate position, eventually causing the movable contact and the corresponding stationary contact on the arm portion 14 to be distributed relatively at an appropriate position to make contact or separation between the movable contact and the stationary contact. In some examples, the first abutting portion 12 and the second abutting portion 13 are each provided obliquely, and a lower end of the abutting portion is connected to one side of the support portion 11, and an upper end of the abutting portion is located above the support portion 11 and connected to a first end of the arm portion 14.

The arm portion 14 may be, for example, a flat plate shape, and the arm portion 14 is disposed either horizontally or obliquely, and when the arm portion 14 is disposed obliquely, an angle between the arm portion 14 and a direction in which a plate surface of the abutting portion to be connected is located is, for example, less than 15 °, or further less than 10 °, or further less than 5 °, and the second end of the arm portion 14 extends upward.

According to another aspect of an embodiment of the present invention, there is provided an outlet terminal assembly, as shown in fig. 6, comprising: a conductive connecting portion 21, a first stationary contact 22, a second stationary contact 23, and an outlet terminal 24;

wherein the conductive connection part 21 includes: the terminal connection section 211, the first contact connection section 212, the guide section 213, and the second contact connection section 214 are connected in sequence.

The first stationary contact 22 is located on the top surface of the first contact connecting section 212, the second stationary contact 23 is located on the bottom surface of the second contact connecting section 214, and the first stationary contact 22 is located obliquely below the second stationary contact 23. The outlet terminal 24 is connected to the terminal connection section 211.

The outlet terminal assembly provided by the embodiment of the invention can be used for switches, such as a midway switch and the like, and the outlet terminal assembly is used for the midway switch, for example, the top surface of the first fixed contact connecting section 212 is the surface of the first fixed contact connecting section 212 facing to a panel of the midway switch; the bottom surface of the second contact connecting section 214 is the surface of the second contact connecting section 214 that faces away from the face of the mid-trip switch.

The outlet terminal assembly provided by the embodiment of the present invention can cooperate with the seesaw having the above-described structure of the embodiment of the present invention, by making the conductive connecting portion 21 include the guide segment 213, the guide segment 213 is designed to enable the first contact connecting segment 212 and the second contact connecting segment 214 to be respectively delivered to the proper positions. The first contact connecting section 212 is located obliquely below the second contact connecting section 214, so that the first stationary contact 22 is located obliquely below the second stationary contact 23, that is, the first stationary contact 22 and the second stationary contact 23 have a certain distance therebetween not only in the up-down direction, but also in the horizontal direction perpendicular to the up-down direction, which enables the outlet terminal assembly provided by the embodiment of the present invention to be arranged in a crossed manner in two side-by-side manner to correspond to two seesaws arranged in side-by-side manner when the outlet terminal assembly is used for half-way pulling of a switch (see fig. 4 and 7). In particular, the spacing in the horizontal direction between the first and second

stationary contacts

22, 23 enables the two stationary contacts to be adapted to two paddles arranged side by side in the horizontal direction; the spacing in the up-down direction between the first and second

stationary contacts

22, 23 enables the two stationary contacts to be adapted to the moving contacts of the two different seesaws described above, which are located on the top and bottom surfaces.

It can be seen that, as shown in fig. 4, when the outlet terminal assembly is used in the middle pulling switch, the structure of the rocker can be adaptively designed such that, as described above in the embodiments of the present invention, two rockers are arranged side by side (referred to as the first rocker 101 and the second rocker 102, respectively), and accordingly, the positions of the two outlet terminal assemblies (referred to as the first outlet terminal assembly 201 and the second outlet terminal assembly 202, respectively) are determined such that the first outlet terminal assembly 201 and the second outlet terminal assembly 202 are located on the same side as the arm 14 of the rocker. Thus, the first stationary contact 22 of the first outlet terminal assembly 201 is adapted to contact the first movable contact 15 of the first rocker 101, and the second stationary contact 23 of the first outlet terminal assembly 201 is adapted to contact the second movable contact 16 of the second rocker 102; the first fixed contact 22 of the second outlet terminal assembly 202 is used for contacting with the first movable contact 15 of the second rocker 102, and the second fixed contact 23 of the second outlet terminal assembly 202 is used for contacting with the second movable contact 16 of the first rocker 101, so that the two-way reversing function of the midway trigger switch can be realized.

Based on the structure of the outlet terminal assembly and the rocker according to the embodiment of the present invention, the first outlet terminal assembly 201 and the second outlet terminal assembly 202 can be located on the same side as the arm 14 of the rocker, that is, the first outlet terminal assembly 201 and the second outlet terminal assembly 202 no longer occupy the space on the two opposite sides of the rocker in the length direction thereof at the same time, but only occupy the space on one side in the length direction thereof, so that the space on the other side of the rocker opposite to the occupied side is empty. In this way, the first and second

inlet terminal assemblies

301, 302 can be adapted such that they are located at the empty space on the other side of the paddle. The incoming line terminal assembly and the outgoing line terminal assembly only occupy the space on two sides of the rocker distributed along the length direction of the rocker, and the space on two sides of the rocker distributed along the width direction of the rocker is prevented from being occupied, so that the width of the midway switch is obviously reduced, and the volume of the midway switch is further reduced.

In some possible implementations, as shown in fig. 6, the guide section 213 includes: a first sub guide segment 2131, a second sub guide segment 2132 and a third sub guide segment 2133; the first sub-guide section 2131, the second sub-guide section 2132 and the third sub-guide section 2133 are connected in sequence, the second sub-guide section 2132 extends in the vertical direction, the first sub-guide section 2131 and the third sub-guide section 2133 are respectively located on two opposite sides of the second sub-guide section 2132, a first included angle is formed between the second sub-guide section 2132 and the first sub-guide section 2131, and a second included angle is formed between the second sub-guide section 2132 and the third sub-guide section 2133.

An end of the first sub guide segment 2131 away from the second sub guide segment 2132 is connected with the first contact connecting segment 212; an end of the third sub guide segment 2133 remote from the second sub guide segment 2132 is connected to the second contact connecting segment 214.

The second sub-guide segment 2132 is used for making the second contact connecting segment 214 and the first contact connecting segment 212 have a distance therebetween in the vertical direction, and the first sub-guide segment 2131 and the third sub-guide segment 2133 are used for making the second contact connecting segment 214 and the first contact connecting segment 212 have a distance therebetween in the horizontal direction.

The second sub-guide segment 2132 and the first sub-guide segment 2131 form a first included angle therebetween, and the second sub-guide segment 2132 and the third sub-guide segment 2133 form a second included angle therebetween, for example, the first included angle and the second included angle may be 60 ° to 120 °. In some examples, the first angle and the second angle are both 90 °, which makes the forming and manufacturing process of the conductive connection portion 21 simpler and facilitates reducing the size of the conductive connection portion 21.

An end of the first sub guide segment 2131 remote from the second sub guide segment 2132 is connected to the first contact connecting segment 212, and in some examples, both the first sub guide segment 2131 and the first contact connecting segment 212 extend in a horizontal direction and a top surface and a bottom surface of both remain flat, respectively.

The first contact connecting section 212 is simultaneously connected with the terminal connecting section 211 and the guide section 213, i.e., the first sub guide section 2131. The terminal connection section 211 and the guide section 213 may be connected to opposite sides of the first contact connection section 212, respectively, or the terminal connection section 211 and the guide section 213 may be connected to adjacent sides of the first contact connection section 212, respectively. In the embodiment of the present invention, as shown in fig. 6, the terminal connection section 211 and the guide section 213 are respectively connected to two adjacent sides of the first contact connection section 212, and since the guide section 213 is located at one side of the first contact connection section 212 along the width direction of the half-pulling switch, the terminal connection section 211 is located at the adjacent side rather than the opposite side (i.e. along the width direction), so that after the terminal connection section 211 is connected to the outgoing terminal 24, the outgoing terminal 24 does not occupy a space along the width direction, which is beneficial to reducing the width of the half-pulling switch.

In some examples, the terminal connecting section 211 is connected perpendicular to the first contact connecting section 212, and the terminal connecting section 211 extends downward such that the outlet terminal 24 is located in a space below the first contact connecting section 212.

When used in a mid-trip switch, referring to fig. 7 and 8, two outlet terminal assemblies are used, namely, a first outlet terminal assembly 201 and a second outlet terminal assembly 202 are located on the same side as the arm 14 of the rocker, and the first outlet terminal assembly 201 and the second outlet terminal assembly 202 are arranged side by side and across to cooperate with the two rockers arranged side by side.

The guide segment 213 of the second outlet terminal assembly 202 is brought closer to the rocker than the guide segment 213 of the first outlet terminal assembly 201, i.e., the shielding groove 2134 provided on the guide segment 213 of the first outlet terminal assembly 201 serves to shield the guide segment 213 of the second outlet terminal assembly 202 to reduce the arrangement space. The second contact connecting segment 214 of the first outlet terminal assembly 201 and the second contact connecting segment 214 of the second outlet terminal assembly 202 are arranged side by side along the width direction of the mid-way trip switch, the second contact connecting segment 214 of the first outlet terminal assembly 201 is positioned above the arm portion 14 of the first rocker 101 such that the respective second movable contact 16 and second stationary contact 23 are positioned opposite, and at the same time, the second contact connecting segment 214 of the second outlet terminal assembly 202 is positioned above the arm portion 14 of the second rocker 102 such that the respective second movable contact 16 and second stationary contact 23 are positioned opposite.

Therefore, when the outgoing terminal assembly and the rocker provided by the embodiment of the invention are matched, the width of the midway trigger switch can be obviously reduced, and the volume of the midway trigger switch is further reduced.

According to another aspect of the embodiments of the present invention, there is provided a midway tripping switch, as shown in fig. 4, including: a first rocker 101, a second rocker 102, a first outgoing terminal assembly 201 and a second outgoing terminal assembly 202, wherein the first rocker 101 and the second rocker 102 are all any one of the rockers provided by the embodiment of the present invention, and the first outgoing terminal assembly 201 and the second outgoing terminal assembly 202 are all any one of the outgoing terminal assemblies provided by the embodiment of the present invention.

The first and second

outlet terminal assemblies

201 and 202 are arranged side by side and crosswise, the first contact connecting segment 212 of the first outlet terminal assembly 201 and the first contact connecting segment 212 of the second outlet terminal assembly 202 are arranged side by side along the width direction of the mid-way trigger switch, the first contact connecting segment 212 of the first outlet terminal assembly 201 is located below the arm 14 of the first rocker 101 so that the respective first movable contact 15 and first stationary contact 22 are in opposite positions, and at the same time, the first contact connecting segment 212 of the second outlet terminal assembly 202 is located below the arm 14 of the second rocker 102 so that the respective first movable contact 15 and first stationary contact 22 are in opposite positions. The guide segment 213 of the second outlet terminal assembly 202 is brought closer to the rocker than the guide segment 213 of the first outlet terminal assembly 201, i.e., the shielding groove 2134 provided on the guide segment 213 of the first outlet terminal assembly 201 serves to shield the guide segment 213 of the second outlet terminal assembly 202 to reduce the arrangement space. The second contact connecting segment 214 of the first outlet terminal assembly 201 and the second contact connecting segment 214 of the second outlet terminal assembly 202 are arranged side by side along the width direction of the mid-way trip switch, the second contact connecting segment 214 of the first outlet terminal assembly 201 is positioned above the arm portion 14 of the first rocker 101 such that the respective second movable contact 16 and second stationary contact 23 are positioned opposite, and at the same time, the second contact connecting segment 214 of the second outlet terminal assembly 202 is positioned above the arm portion 14 of the second rocker 102 such that the respective second movable contact 16 and second stationary contact 23 are positioned opposite.

In some possible implementations, as shown in fig. 9, the guide segment 213 of the first outlet terminal assembly 201 has a first avoidance slot 2134 thereon, the first avoidance slot 2134 being used to avoid the guide segment 213 of the second outlet terminal assembly 202; alternatively, the guide segment 213 of the second outlet terminal assembly 202 has a second avoidance slot 2134, and the second avoidance slot 2134 is used to avoid the guide segment 213 of the first outlet terminal assembly 201.

Through the design of the avoiding groove 2134, the crossing arrangement between the conductive connecting part 21 of the first outlet terminal assembly 201 and the conductive connecting part 21 of the second contact terminal assembly is more compact, and the volume of the midway trigger switch is reduced.

Further, as shown in fig. 10 and 11, the midway trigger switch provided by the embodiment of the present invention further includes: a first inlet terminal assembly 301 and a second inlet terminal assembly 302; wherein the first and second

inlet terminal assemblies

301, 302 each have a support end 3001 and a terminal end 3002. The support end 3001 of the first incoming terminal assembly 301 is movably connected to the support portion 11 of the first rocker 101 to allow the first rocker 101 to swing around the support end 3001; the terminal end 3002 of the first inlet terminal assembly 301 is located on opposite sides of the arm portion 14 of the first paddle 101; the support end 3001 of the second inlet terminal assembly 302 is movably connected with the support portion 11 of the second rocker 102 to allow the second rocker 102 to swing around the support end 3001; the terminal end 3002 of the second inlet terminal assembly 302 is on opposite sides of the arm 14 of the second rocker 102.

In the embodiment of the present invention, the first and second

inlet terminal assemblies

301 and 302 both function as a support rocker and a connection inlet terminal 34. In the midway trigger switch, because the first and second

outlet terminal assemblies

201 and 202 are located on the same side as the arm portion 14 of the rocker, the first and second

outlet terminal assemblies

201 and 202 no longer occupy the space on two opposite sides of the rocker in the length direction thereof at the same time, but only occupy the space on one side, so that the space on the other side of the rocker opposite to the occupied side is vacant. Thus, the first and second

inlet terminal assemblies

301 and 302 are located at the empty space of the rocker along the other side of the rocker in the length direction, i.e. the terminal end 3002 of the first inlet terminal assembly 301 and the arm 14 of the first rocker 101 are located at opposite sides, and the terminal end 3002 of the second inlet terminal assembly 302 and the arm 14 of the second rocker 102 are located at opposite sides. Therefore, the incoming terminal assembly and the outgoing terminal assembly only occupy the spaces on two sides of the rocker distributed along the length direction of the rocker, and the spaces on two sides of the rocker distributed along the width direction of the rocker are prevented from being occupied, so that the width of the midway switch is obviously reduced, and the volume of the midway switch is further reduced.

The above-mentioned halfway-pulling switch is actually a one-position halfway-pulling switch, which is more compact and miniaturized. Referring to fig. 5, when a two-position midway switch is prepared, two such one-position midway switches can be arranged side by side along the width direction, which is beneficial to reducing the volume of the two-position midway switch (through tests, the volume of the formed two-position midway switch can be reduced to about half of the volume of the traditional two-position midway switch). In addition, the one-position midway switch and the two-position midway switch can share functional components, so that the universality of the functional components of the midway switch is improved, the additional wiring during the formation of the two-position midway switch is avoided, the structure and the assembly process are simplified, the cost is reduced, the service life is prolonged, and the user experience is improved.

In some possible implementations, as shown in FIG. 12, the first and second

inlet terminal assemblies

For example, the supporting end 3001 of the conductive supporting portion 31 is circular arc.

In order to improve the strength of the conductive support 31, a metal plate may be bent at a predetermined position to form an arc-shaped top portion as the support end 3001, and the rest of the laminated plate may be used as the support body.

In some examples, the conductive guide 32 includes: first direction section, second direction section and third direction section, wherein, the one end of first direction section is connected with the bottom of electrically conductive supporting part 31 is perpendicular, the other end that deviates from electrically conductive supporting part 31 of first direction section is connected with the bottom of second direction section is perpendicular, the top of second direction section is connected with the one end of third direction section is perpendicular, the third direction section is parallel with first direction section, the other end that deviates from the second direction section of third direction section is connected with electrically conductive connecting portion 21 is perpendicular. In this manner, wire inlet terminal 34 is disposed on one side of the respective paddle with conductive guide 32, i.e., wire inlet terminal 34 and wire outlet terminal 24 are located on opposite sides of the paddle.

The conductive connection portion 33 extends in the up-down direction and is located below the third guide section, and the conductive connection portion 33 may be connected to the corresponding inlet terminal 34 by means of plugging.

Finally, the outlet terminal 24 of the second outlet terminal assembly 202 is closer to the corresponding rocker than the outlet terminal 24 of the first outlet terminal assembly 201, and the outlet terminal 24 of the first outlet terminal assembly 201 has more operating space.

With such an arrangement, when the outlet terminal 24 is assembled, the first outlet terminal assembly 201 can be assembled first, and then the second outlet terminal assembly 202 can be assembled in sequence, so that the difficulty caused by the fact that two outlet terminal assemblies are arranged in a crossed manner first and then assembled at the same time is avoided, and the assembly difficulty of the outlet terminal assemblies is facilitated to be simplified.
