Referring to FIGS. 1, 9, and 10, the dual conduction key switch provided in this embodiment includes a base (1), a cover (2) provided above the base (1), and a conductive core (3), The cover 2 is covered on the base 1 to form a receiving chamber, and the conductive core 3 is provided in the receiving chamber, and an opening is provided on the cover 2 to allow the top of the conductive core 3 to penetrate ( 21) is opened, pressing down on the conducting core (3) to trigger conduction of the key switch.

The key switch of this embodiment also includes a first conduction module (4) and a second conduction module (5) that are sequentially turned on by triggering by the conduction core (3), and when the conduction core (3) is pressed down, the first conduction module (4) and the second conduction module (5) are turned on. 1 The conduction module 4 and the second conduction module 5 are connected back to back, that is, the first conduction module 4 and the second conduction module 5 have different conduction steps, and the key switch is double conductive. Implement the function.

Specifically, as shown in FIG. 2, this embodiment includes at least one first conductive trigger component 31 and a second conductive trigger component corresponding to the first conductive module 4, respectively, on the conductive core 3. It is provided with at least one second conduction trigger part 32 corresponding to the module 5, and the first conduction trigger part 31 triggers the first conduction module 4 to conduct a conduction stroke and a second conduction trigger. The conduction process in which the component 32 triggers the second conduction module 5 to conduct electricity is different. Therefore, when pressing the conductive core 3 downward, the first conduction trigger part 31 triggers the first conduction module 4 to become conductive first, and when continuously pressing the conduction core 3, the second conduction trigger is triggered. The component 32 can later become conductive by triggering the second conduction module 5 .

In addition, a first inclined surface 311 is formed on the side of the first conductive trigger part 31, a second inclined surface 321 is formed on the side of the second conductive trigger part 32, and the first The inclination of the inclined surface 311 is greater than the inclination of the second inclined surface 321, and since the inclinations of the first inclined surface 311 and the second inclined surface 321 are different, the first conductive trigger part 31 and the second conductive trigger When the component 32 moves downward along the conductive core 3, sequential conduction between the first conduction module 4 and the second conduction module 5 can be implemented.

In this embodiment, both the first conduction module 4 and the second conduction module 5 have a stationary piece conduction structure, and the specific structures are as follows.

As shown in FIG. 3, the first conduction module 4 includes a first stop piece 41 and a first moving piece 42, and a first stop contact on the first stop piece 41. 411, and a first moving contact 421 corresponding to a first stop contact 411 on the first moving piece 42, and a first moving contact 421 on the first moving piece 42. 1 Form at least one first contact protruding block 422 corresponding to the conductive trigger part 31. Specifically, the quantity of the first contact protruding block 422 and the first conductive trigger part 31 can be set to two each, and can also be set to correspond one by one. Regarding the installation of the first stationary piece 41 and the first movable piece 42, the first stationary piece 41 and the first movable piece 42 are installed on the base 1, and a conductive core ( 3) It may be located on the outside of the first conductive trigger part 31, specifically, the first stop piece 41 is located on the inside, and the first moving piece 42 is located on the outside, As shown in Figure 8. In addition, the lower ends of the first stationary piece 41 and the first moving piece 42 penetrate the lower surface of the base 1 and are electrically connected to the PCB board. While the conductive core 3 moves up and down, the first conductive module 4 does not undergo longitudinal displacement.

As shown in FIG. 4, the second conductive module 5 includes a second stop piece 51 and a second moving piece 52, and a second stop contact on the second stop piece 51. (511), and a second moving contact 521 corresponding to a second stop contact 511 on the second moving piece 52, and a second moving contact 521 on the second moving piece 52. 2 Form at least one second contact protruding block 522 corresponding to the conductive trigger part 32. Specifically, the quantity of the second contact protruding block 522 and the second conductive trigger part 32 can be set to two each, and can also be set to correspond one by one. Regarding the installation of the second stationary piece 51 and the second movable piece 52, the second stationary piece 51 and the second movable piece 52 are installed on the base 1, and a conductive core ( 3) It may be located on the outside of the second conductive trigger part 32, specifically, the second stop piece 51 is located on the inside, and the second moving piece 52 is located on the outside, As shown in Figures 8 and 9. In addition, the lower ends of the second stationary piece 51 and the second moving piece 52 penetrate the lower surface of the base 1 and are electrically connected to the PCB board. While the conductive core 3 moves up and down, the second conductive module 5 does not undergo longitudinal displacement.

In this embodiment, both the first movable piece 42 and the second movable piece 52 are made of a material having certain elasticity, for example, stainless steel.

Under the initial non-pressing state, as shown in FIG. 5, when the first conductive trigger part 31 supports the first contact protruding block 422 on the first movable piece 42 toward the outside, the first movable piece 42 (42) The upper part is curved and deformed toward the outside, causing the first moving contact 421 and the first stationary contact 411 to be separated, so that the first conductive module 4 is in a non-conductive state. In addition, when the second conductive trigger part 32 supports the second contact protruding block 522 on the second moving piece 52 toward the outside, the upper part of the second moving piece 52 is curved and deformed toward the outside. 2 The moving contact 521 and the second stationary contact 511 are separated, so that the second conduction module 5 is in a non-conductive state.

When pressing down on the conductive core 3, as shown in Figure 6, the conductive core 3 moves downward constantly, and the conductive core 3 moves down to the first contact protruding block 422, When in contact with the first inclined surface 311 on the first conductive trigger part 31, under the guiding action of the first inclined surface 311, the upper part of the first movable piece 42 is in contact with the first movable contact 421 and the first movable contact 421. When the stop contact 411 springs back inward until it makes contact, the first conductive module 4 becomes conductive. In this process, the second contact protruding block 522 and the second inclined surface 321 on the second conductive trigger part 32 come into contact, and under the guiding action of the second inclined surface 321, the second moving piece 52 Since the upper part springs back toward the inside and the inclination of the first inclined surface 311 is greater than that of the second inclined surface 321, the first moving contact 421 and the first stopping contact 411 inevitably conduct first, and the first 1 When the conduction module 4 has just become conductive, the second moving contact 521 is not yet in contact with the second stationary contact 511. That is, in this first section in which the conductive core 3 moves downward, the first conductive module 4 is conducted and the second conductive module 5 is not conducted.

If the conductive core 3 is continuously pressed down, as shown in FIG. 7, the conductive core 3 continues to move downward, and under the guiding action of the first inclined surface 311, the first moving piece 42 ) When the upper part continues to spring back inward and the first moving contact 421 and the first stationary contact 411 are in contact throughout, the first conduction module 4 continues to conduction. In this process, under the guiding action of the second inclined surface 321, the upper part of the second moving piece 52 continues to spring back inward until the second moving contact 521 and the second stationary contact 511 come into contact. , the second conduction module 5 is conducted. That is, in this second section in which the conductive core 3 moves downward, the first conductive module 4 continues to conduction, and the second conductive module 5 begins to conduction. This implements sequential continuity between the first conduction module 4 and the second conduction module 5.

In the process of pressing the conductive core 3 downward, the spring 6 provided between the conductive core 3 and the base 1 is compressed.

When releasing the pressing of the conductive core 3, under the action of the elastic recovery force of the spring 6, the conductive core 3 is restored to its upward position, and the inclination of the first inclined surface 311 is changed to that of the second inclined surface 321. Because it is greater than the slope, the second conduction module 5 is interrupted first, and the first conduction module 4 is interrupted later, restoring the initial non-pressed state.

Example 2

The main difference between this embodiment and Example 1 is that, referring to FIGS. 11 to 14, the first conductive module 4 is an optical conductive module A 43 electrically connected to the PCB board 7, and the The second conductive module 5 is an optical conductive module B (53) electrically connected to the PCB board 7, and the first conductive trigger component 31 is a light blocking protruding block A (312), and the second conductive trigger component 31 is a light blocking protruding block A (312). The trigger part 32 is a light blocking protruding block B (322), and the distance between the corresponding light blocking protruding block A (312) and the optical conduction module A (43) is the distance between the light blocking protruding block B (322) and the optical conducting module B (53). ) is smaller than the distance between them. When the conductive core (3) is pressed and moved down, the light blocking protruding block A (312) and the light blocking protruding block B (322) move down together, and the light blocking protruding block A (312) and the light conducting module A ( 43) is smaller than the distance between the light-blocking protruding block B (322) and the optical conduction module B (53), so the light-blocking protruding block A (312) arrives at the light-conducting module A (43) first, and also the light-conducting module B (53). It blocks the light path of module A (43), and the light blocking protruding block B (322) later arrives at light conduction module B (53) and also blocks the light path of light conduction module B (53). Therefore, the optical conduction module A (43) generates an optical path blocking signal earlier than the optical conduction module B (53), that is, the optical conduction module A (43) conducts first, and the optical conduction module B (53) conducts first. Continuity is established later, thereby realizing the purpose of successive continuity. This embodiment implements the double conduction function of the switch by differentiating the first and second conduction cycles.

The distance between the light blocking protruding block A (312) and the optical conductive module A (43) is smaller than the distance between the light blocking protruding block B (322) and the optical conducting module B (53), and can be implemented using the following two methods. .

(1) The height of the light blocking protruding block A (312) is the same as the height of the light blocking protruding block B (322), and the height of the light conducting module A (43) is higher than the height of the light conducting module B (53). As shown in Figures 13 to 16. When the conductive core (3) is pressed and moved down, the light blocking protruding block A (312) and the light blocking protruding block B (322) move down together, and in the process of moving down, the light blocking protruding block A (312) ) is always the same as the height of the light blocking protruding block B (322). Because the height of the optically conductive module A (43) is higher than the height of the optically conductive module B (53), the light blocking protruding block A (312) arrives at the optically conductive module A (43) first, and also the optically conductive module A ( 43), and the light blocking protruding block B (322) later arrives at the light conduction module B (53) and also blocks the light path of the light conduction module B (53). Therefore, the optical conduction module A (43) generates a signal that the optical path is blocked earlier than the optical conduction module B (53), that is, the optical conduction module A (43) conducts first, and the optical conduction module B (53) conducts first. ) is connected later, thereby realizing the purpose of first-to-follow connection.

(2) The height of the light blocking protruding block A (312) is lower than the height of the light blocking protruding block B (322), and the height of the light conducting module A (43) is the same as the height of the light conducting module B (53). . When designing the specific structure, simply design the position height of the light blocking protruding block A (312) on the conductive core (3) to be lower than the position height of the light blocking protruding block B (322) on the conducting core (3). When the conductive core 3 is pressed and moved downward, the light blocking protruding block A (312) and the light blocking protruding block B (322) move downward simultaneously along the conducting core (3), and in the process of moving downward, The height of the light blocking protruding block A (312) is always lower than the height of the light blocking protruding block B (322). Because the height of the optical conduction module A (43) is the same as the height of the optical conduction module B (53), the light blocking protruding block A (312) arrives at the optical conduction module A (43) first, and also the optical conduction module A ( 43), and the light blocking protruding block B (322) later arrives at the light conduction module B (53) and also blocks the light path of the light conduction module B (53). Therefore, the optical conduction module A (43) generates a signal that the optical path is blocked earlier than the optical conduction module B (53), that is, the optical conduction module A (43) conducts first, and the optical conduction module B (53) conducts first. ) is connected later, thereby realizing the purpose of first-to-follow connection.

For the convenience of moving the light blocking protruding block A (312) and the light blocking protruding block B (322) up and down, the present embodiment includes the light blocking protruding block A (312) and the light blocking protruding block B ( 322) forms a first position yielding opening 11 that allows it to move up and down, as shown in FIGS. 15 and 16.

In this embodiment, the optical conduction module A (43) and the optical conduction module B (53) have the same structure and include light emitting elements (431, 531) and light receiving elements (432, 532), respectively. Under a situation where no blocking structure exists between the light emitting elements (431, 531) and the light receiving elements (432, 532), the light emitting elements (431, 531) emit an optical signal, and the light receiving elements (432, 532) receives an optical signal, and when a blocking structure appears between the two, the light receiving elements 432 and 532 cannot receive the optical signal emitted by the light emitting elements 431 and 531, that is, an optical path blocking signal is generated. Create.

A key switch using an optical conduction module is an optical axis key switch. The operating principle is as follows.

Under natural conditions, the light-blocking protruding block on the conductive core 3 cannot reach the light-conducting module, and the light-receiving element in the light-conducting module can normally receive the optical signal emitted by the light-emitting element, and the PCB substrate 7 Under these circumstances, through pre-setting of the upper circuit, the key switch is placed in a cut-off state.

When the conducting core 3 is pressed down, the conducting core 3 moves downward simultaneously by actuating the light blocking protruding block until the light blocking protruding block is inserted between the light emitting element and the light receiving element, By blocking the optical path between the light receiving element and the light receiving element, the light receiving element cannot receive the optical signal emitted by the light emitting element. That is, when the optical path blocking signal is generated, the key switch is set to conduction.

When releasing the pressing of the conducting core 3, under the action of the elastic recovery force of the spring 6, the conducting core 3 recovers its upward position, operates the light blocking protruding block to move upward, and the light blocking protruding block moves upward. When leaving between the light-emitting element and the light-receiving element, when the light-receiving element again receives the optical signal emitted by the light-emitting element, the key switch is restored to the cut-off state.

In this embodiment, since the distance between the light blocking protruding block A (312) and the optical conductive module A (43) is smaller than the distance between the light blocking protruding block B (322) and the optical conducting module B (53), the conductive core (3) When is pressed down, the light blocking protruding block A (312) is first inserted between the light emitting element 431 and the light receiving element 432, so that the light emitting element 431 emits light to the light receiving element 432. The light blocking protruding block B (322) blocks the signal and later blocks the optical signal emitted by the light emitting element (431) to the light receiving element (432), that is, the light conduction module A (43) is an optical conduction module. Since the optical path blocking signal is generated first compared to B (53), that is, the optical conduction module A (43) is conducted first, and the optical conduction module B (53) is conducted later, the purpose of first and second conduction is realized.

By releasing the pressing of the conductive core (3), when the conductive core (3) moves upward and recovers its position, the light blocking protruding block B (322) first leaves the light conduction module B (53), and then the light conduction module B ( The optical path blocking signal generated by 53) disappears first, and the optical path blocking signal generated by optical conduction module A (43) disappears later, that is, the optical conduction module B (53) is connected to the optical conduction module A (43). It is blocked first compared to .

Example 3

The main difference between this embodiment and Example 1 is that, referring to FIGS. 17 to 20, the first conductive module 4 is an inductive switch A 45 electrically connected to the PCB board 7, and the first conductive module 4 is an inductive switch A 45 electrically connected to the PCB board 7. 2 The conduction module 5 is an induction switch B (55) electrically connected to the PCB board 7, the first conduction trigger component 31 is a magnet A (312), and the second conduction trigger component 32 is magnet B (323), and the distance between magnet A (313) and induction switch A (45) is smaller than the distance between magnet B (323) and induction switch B (55). When the conducting core (3) is pressed and moved down, magnet A (313) and magnet B (323) move down together, and the distance between magnet A (313) and induction switch A (45) is equal to the distance between magnet B (323) and Because it is smaller than the distance between the induction switches B (55), the induction switch A (45) first induces the magnetism of the magnet A (313), and the induction switch B (55) later induces the magnetism of the magnet B (323). That is, the first conduction module 4 is connected first, and the second conduction module 5 is connected later, thereby realizing the purpose of the first conduction module 4 and the second conduction module 5 being connected first. Accordingly, this embodiment implements the switch double conduction function through the fact that the first conduction module 4 and the second conduction module 5 have different conduction strokes.

As the distance between magnet A (313) and induction switch A (45) is smaller than the distance between magnet B (323) and induction switch B (55), it can be implemented using the following two methods.

(1) The height of the magnet A (313) is the same as the height of the magnet B (323), and the height of the induction switch A (45) is higher than the height of the induction switch B (55), as shown in FIGS. 18 to 21 As shown. When the conductive core (3) is pressed and moved downward, magnet A (313) and magnet B (323) move downward simultaneously along the conductive core (3), and in the process of moving downward, magnet A (313) The height and the height of magnet B (323) are the same throughout. Since the height of induction switch A (45) is higher than the height of induction switch B (55), when magnet A (313) approaches induction switch A (45) preferentially compared to magnet B (323), induction switch A (45) ) first induces the magnetism of the magnet A (313), and the induction switch B (55) later induces the magnetism of the magnet B (323), so that the first conduction module (4) conducts first, and the second conduction module (5) This implements the purpose that is followed later.

(2) The height of the magnet A (313) is lower than the height of the magnet B (323), and the height of the induction switch A (45) is the same as the height of the induction switch B (55). When designing the specific structure, simply design the position height of magnet A (313) on the conductive core (3) to be lower than the position height of magnet B (323) on the conduction core (3). When the conductive core (3) is pressed and moved downward, magnet A (313) and magnet B (323) move downward simultaneously along the conductive core (3), and in the process of moving downward, magnet A (313) The position height is always lower than the position height of magnet B (323). Since the height of induction switch A (45) is the same as the height of induction switch B (55), when magnet A (313) approaches induction switch A (45) preferentially compared to magnet B (323), induction switch A (45) ) first induces the magnetism of the magnet A (313), and the induction switch B (55) later induces the magnetism of the magnet B (323), so that the first conduction module (4) conducts first, and the second conduction module (5) This implements the purpose that is followed later.

Regarding the installation method of magnet A (313) and magnet B (323) on the conductive core (3), as shown in Figures 19 and 20, in this embodiment, the side sides of the conductive core (3) each face outward. It is provided with a protruding installation part A (33) into which the magnet A (313) is inserted and a protruding installation part B (34) into which the magnet B (323) is inserted. When the protruding installation part A (33) and the protruding installation part B (34) move up and down as a whole along the conductive core (3), the magnet A (313) and the magnet B (323) also move up and down simultaneously, creating double conduction in front and back. Implement the purpose.

When the conductive core (3) is pressed down, the conductive core (3) moves downward by actuating the magnet, and the conductive core (3) is pressed downward at a constant stroke, so that the magnet and the Hall element on the PCB board (7) When a certain distance is reached, the Hall element induces magnetism, that is, the Hall element generates a signal (e.g., a signal of resistance value change, a signal of voltage value change, etc.), and as the magnetic force increases, the signal value increases. increases along with it and also increases linearly, and when the electrical performance is output, the circuit is conducted, that is, the key switch is in a conductive state.

When releasing the pressing of the conducting core 3, under the action of the elastic recovery force of the spring 6, the conducting core 3 recovers its upward position, operates the magnet and moves upward, and the distance between the magnet and the Hall element is sufficient. When the Hall element on the PCB board 7 fails to induce the magnetism, that is, when the Hall element does not generate a signal, the circuit is cut off and the key switch is restored to the cut-off state.
