When the knob rotates according to functional requirements, the locking structure drives the corresponding locking slots of the AC switch control button and the DC switch conduction assembly, causing the AC switch control button and the DC switch conduction assembly to rotate with the knob, thereby realizing the linkage of AC and DC control switches of the integrated AC / DC control rotary switch.

[0009] Preferably, when the two ends of the AC switch control button are not directly opposite the center of the fixed terminal or the spring terminal, one set of contacts A and B diagonally opposite each other are closed and the other set is open.

[0010] Preferably, the housing is divided into two accommodating cavities by a fixing plate, the base control assembly is installed in one of the accommodating cavities, and a reset torsion spring is installed on the other accommodating cavity on one side of the formed passage, and an elastic positioning structure is designed next to the reset torsion spring to match the stop engagement part on the knob.

[0028] Please see Figures 1 to 4 The integrated AC / DC control rotary switch of this embodiment includes: a knob 1, a base control assembly 2 mounted on the knob 1, an AC switch control button 3 and a DC control board 4 mounted in the base control assembly 2, a DC switch conduction assembly 5 covering the DC control board 4, and a fixing screw 6 that passes through the DC switch conduction assembly 5, the DC control board 4, the AC switch control button 3 and the base control assembly 2 in sequence and is fixedly connected to the knob 1.

[0029] In a preferred embodiment, the knob 1 is provided with a rotating shaft 11, and a wave-shaped stop engagement portion 12 is formed on the side of the rotating shaft 11. A locking structure 111 is protruding on the rotating shaft 11, and the locking structure 111 is a protruding plate that protrudes from the periphery of the rotating shaft 11 at intervals.

[0030] The base control assembly 2 includes: a set of fixed terminals 22 and a set of spring terminals 23, each with double contacts and mirror-mounted, installed inside the housing 21; each spring terminal 23 has a contact B extending from a high-voltage spring 231 to a corresponding contact A of the fixed terminal 22; the AC switch control button 3 is installed between the fixed terminals 22 and the spring terminals 23, and controls the corresponding contact A and contact B to be turned on / off in conjunction with the rotating shaft 11. Specifically, each spring terminal 23 includes: a central leg installed on the housing 21; a high-voltage spring 231 that is snapped and fixed to one side of the central leg, with both ends facing the two fixed terminals 22 and gradually expanding in opening; and contacts B installed at both ends of the high-voltage spring 231, directly opposite to contact A; when the two ends of the AC switch control button 3 are not directly opposite the center of the fixed terminal 22 or the spring terminal 23, one set of contacts A and contact B diagonally closes and the other set opens. More specifically, the housing 21 is divided into two accommodating cavities by a fixing plate a. The base control assembly 2 is installed in one of the accommodating cavities. A reset torsion spring b1 is installed on the other accommodating cavity, next to the formed passageway. An elastic positioning structure b2 is designed next to the reset torsion spring b1 to match the stop engagement part 12 on the knob 1. The elastic positioning structure b2 includes a fixing block b23 with one end fixed to the fixing post b21 and the other end having a protrusion formed and fixed by the positioning torsion spring b22. One end of the positioning torsion spring b22 is hooked into the through hole formed by the fixing block b23. When the knob 1 is rotated, the stop engagement part 12 slides along the protrusion of the fixing block b23. When the external force is removed, the protrusion and the corresponding groove of the stop engagement part 12 are locked and positioned.

[0031] The AC switch control knob 3 is a rectangular structure with chamfered top corners, and has a first engaging rotating part 31 inside that engages with the rotating shaft. Specifically, the first engaging rotating part 31 has a slot that matches the locking structure 111. When the rotating shaft 11 rotates, the locking structure 111 drives the AC switch control knob 3 to rotate, thereby controlling the AC conduction and disconnection.

[0032] The DC control board 4 is designed with several DC gear positions, which are covered by the rotating shaft 11 and installed in the accommodating cavity. The DC switch conduction assembly 5 includes: a rear cover 51 with a protruding locking shaft c that engages with the rotating shaft 11 in the middle, and a low-voltage spring piece 52 that is installed inside the rear cover 51 and has a suspended protruding spring piece abutting part d, which is penetrated by the protruding locking shaft c; the fixing screw 6 passes through the protruding locking shaft c and is interference-fitted with the rotating shaft 11. Specifically, the bayonet of the DC switch conduction assembly 5 is recessed from the open end of the protruding locking shaft c to the other end. The locking structure 111 engages with the bayonet. When the rotating shaft 11 rotates, the bayonet is driven by the locking structure 111 to make the rear cover 51 and the low-voltage spring piece 52 move synchronously with it. The DC switch conduction assembly 5 rotates and abuts to the corresponding gear position, thereby realizing the integrated control and adjustment function of DC and AC.

[0033] The assembly method of this utility model is as follows: the base control component 2 is installed into the knob 1 through the rotating shaft 11; the AC switch control button 3 is installed in a receiving cavity of the base control component 2 with the locking structure 111 of the rotating shaft 11 through the locking slot and is located between the fixed terminal 22 and the spring terminal 23; the DC control board 4 is covered on the AC switch control knob 3 through the rotating shaft 11 and is located in the receiving cavity; the DC switch conduction component 5 is covered on the DC control board 4, and the locking slot formed on it locks the locking structure of the rotating shaft 111; the fixing screw 6 passes through the DC switch conduction component 5 and is interference-fitted into the rotating shaft, thereby fixing the entire structure. Knob 1 controls the rotation of shaft 11. The locking structure 11 on shaft 11 simultaneously matches the locking slots of AC switch control button 3 and DC switch conduction assembly 5, causing AC switch control button 3 to rotate. AC switch control button 3 acts on fixed terminal 22 and spring terminal 23, causing corresponding contacts A and B to be turned on / off, achieving AC control. Simultaneously, the rotation of DC switch conduction assembly 5 activates the corresponding switch position on DC control board 4, synchronously achieving DC control. This allows the product to achieve integrated AC / DC control. The product's structure is compact and reasonable, ensuring product performance while effectively reducing production costs.
