Technical Field

[0001] This utility model relates to the field of electronic switch technology, specifically a rotary switch. Background Technology

[0002] A rotary switch is a switch that controls the opening and closing of a circuit by rotating it. Household appliances such as lamps, fans, and microwave ovens all use rotary switches.

[0003] Existing rotary switches are prone to wiring problems. For example, a rotary switch with publication number CN219575469U discloses an upper cover and a lower cover, which together form a receiving cavity. The receiving cavity contains two contacts electrically connected to a wire, a rotating core, and a rotating assembly. A guide post is provided on the side of the lower cover facing the upper cover, and the two contacts are located on both sides of the guide post. The rotating core is connected to the rotating assembly and is rotatably mounted on the guide post. This rotary switch is wired through two contacts, which are prone to poor contact when connected to the wire, thus requiring further improvement. Utility Model Content

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0024] See Figures 1-6 A rotary switch includes a housing 1, a rotating assembly, a conductive rotating core 4, a first contact 5, and a second contact 6. The conductive rotating core 4, the first contact 5, and the second contact 6 are all disposed within the housing 1. The rotating assembly drives the conductive rotating core 4 to rotate and contact the first contact 5 and the second contact 6. Specifically, when the rotating assembly is turned, causing the conductive rotating core 4 to rotate to a first position, both the first contact 5 and the second contact 6 contact the conductive rotating core 4, thus achieving energization. When the rotating assembly is turned to reset the conductive rotating core 4 to a second position, the first contact 5 and the second contact 6 contact the rotating assembly, thus achieving an de-energized state.

[0025] Both the first contact 5 and the second contact 6 are "S" shaped structures; the first contact 5 includes a first conductive half 7 and a first wiring half 8, the included angle of the end of the first conductive half 7 is less than 90°, and the middle of the first wiring half 8 is provided with a first elastic contact plate 9; the second contact 6 includes a second conductive half 10 and a second wiring half 11, the included angle of the end of the second conductive half 10 is greater than 90°, and the middle of the second wiring half 11 is provided with a second elastic contact plate 12; the housing 1 is provided with two limiting posts 13, the two limiting posts 13 are respectively located in the concave part of the first wiring half 8 and the concave part of the second wiring half 11. When the conductive core 4 rotates to the position of contacting the first conductive half 7 and the second conductive half 10, the first conductive half 7 and the second conductive half 10 clamp the conductive core 4 in both directions, which can better contact and avoid poor contact. The wire abuts against the first elastic contact plate 9 / second elastic contact plate 12. The wire is clamped between the first elastic contact plate 9 / second elastic contact plate 12 and the first wiring half 8 / second wiring half 11, which also plays a better wiring role.

[0026] In this embodiment, the housing 1 includes a bottom shell 14 and a top shell 15, and the bottom shell 14 and the top shell 15 are detachably connected. There are various options for the connection method between the bottom shell 14 and the top shell 15 to achieve a detachable connection, such as a snap-fit ​​connection or a bolt connection.

[0027] In this embodiment, the bottom shell 14 is provided with a receiving groove 16 and a guide shaft 17. The conductive rotating core 4 is sleeved on the guide shaft 17. When the conductive rotating core 4 rotates, the guide shaft 17 has a limiting effect on the conductive rotating core 4 to prevent the conductive rotating core 4 from shifting. The first contact 5 and the second contact 6 are accommodated in the receiving groove 16. The shape of the receiving groove 16 is adapted to the first contact 5 and the second contact 6, so that the first contact 5 and the second contact 6 can be accommodated in the receiving groove 16 and fixed.

[0028] In this embodiment, the rotating assembly includes a knob 2 and a toggle member 3. The toggle member 3 is disposed inside the housing 1 and engaged with the conductive rotating core 4. One end of the knob 2 is engaged with the toggle member 3, and the other end protrudes outside the housing 1. Manually turning the knob 2 causes the toggle member 3 to rotate, which in turn causes the conductive rotating core 4 to rotate.

[0029] In this embodiment, the end of the knob 2 is provided with four inclined locking positions 18 arranged in a circle, and the actuating member 3 is provided with four inclined locking grooves 19 adapted to the inclined locking positions 18. When the knob 2 is rotated, the locking positions engage with the inner walls of the locking grooves and drive the actuating member 3 to rotate.

[0030] In this embodiment, the actuating element 3 is provided with a guide hole 20 at its center, and the knob 2 is provided with an auxiliary shaft 21 at its end. When the knob 2 engages with the actuating element 3, the auxiliary shaft 21 is inserted into the guide hole 20 to prevent displacement during rotation.

[0031] In this embodiment, the conductive rotating core 4 is provided with two locking feet 22 around its perimeter, and the side wall of the actuating member 3 is provided with four locking blocks 23, forming a locking groove between adjacent locking blocks 23. The two locking feet 22 are respectively located in the two locking grooves. When the actuating member 3 rotates, the locking blocks 23 lock the locking feet 22, thereby driving the conductive rotating core 4 to rotate.

[0032] In this embodiment, the bottom shell 14 is provided with two wiring holes 24, which correspond to the first wiring half 8 and the second wiring half 11 respectively. The two wiring holes 24 are used for inserting positive wires and negative wires, and respectively contact the first elastic contact plate 9 and the second elastic contact plate 12.

[0033] The above description is merely a specific embodiment of the present invention, enabling those skilled in the art to understand or implement the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features claimed herein.
