Description

Rotary Switch Structure

technical field

The utility model relates to a switch structure, in particular to a rotary switch structure which can achieve different conduction effects through rotation.

Background technique

The general rotary switch mainly uses the rotation method to turn on different terminals to change the current in the circuit by turning on the terminals with different resistances, and to control the equipment to produce different operating effects through the changed conduction current. Rotary switches can be roughly divided into two types of rotation: stepless and multi-stage. As far as the multi-stage rotary switch is concerned, it is mainly provided with multiple teeth at the bottom of the rotary knob, and the shrapnel is pressed against the teeth, so that the rotary knob is pressed and restricted by the shrapnel to achieve multi-stage when rotating. rotation effect. However, most of the shrapnel are separate parts, and a special position for placing the shrapnel must be provided in addition, so that the shrapnel can be stably pressed against the teeth of the rotary knob. Therefore, this not only increases the processing steps and time, if the shrapnel If the set position is incorrect, it may also affect the conduction effect of the rotary switch. In addition, due to the poor design of the conduction terminal of the current general rotary switch, poor contact is prone to occur after the rotary knob is used for a period of time.

Detailed ways

In order to achieve the above objects and effects, the following will be described in detail with reference to the accompanying drawings and embodiments, so that those skilled in the art can implement the utility model.

First of all, please refer to Fig. 1, Fig. 2, Fig. 3, Fig. 4 and Fig. 5, which are three-dimensional appearance diagrams, three-dimensional exploded diagrams, partial schematic diagrams and preferred embodiment diagrams of the present utility model, as can be clearly seen from Fig. 1 and Fig. 2 Point out that the rotary switch structure 1 of the present utility model includes:

A base 2 has a convex portion 21 and an annular groove 23 formed on its upper end, and a plurality of conducting terminals 24 are provided on the bottom. In addition, a receiving groove 210 is provided in the middle of the convex portion 21, and the two outer sides of the base 2 correspond to Each is provided with two card blocks 22;

A pressing device 3 is arranged in the convex portion 21 of the base 2, and at least one light-emitting element 31 is arranged on its upper end;

A rotating member 4 is sleeved on the convex portion 21 of the base 2, and the outer surface of the bottom side is provided with a plurality of tooth portions 42. In addition, a through groove 41 is provided in the middle position, and a plurality of convex bodies are provided at the bottom 43;

A conducting member 44 is arranged at the bottom of the rotating member 4, and its upper end is provided with a plurality of fixing holes 441 and a plurality of contact ends 442, and the conducting member 44 is combined with the convex body 43 at the bottom of the rotating member 4 through the fixing holes 441 , so that the conducting member 44 can be stably arranged at the bottom of the rotating member 4, see FIG. 3 ;

A cover body 5 is set on the base 2, and its central position is provided with a through hole 50, and two sides are respectively extended with a limit elastic piece 51, and on the other two sides where the limit elastic piece 51 is respectively provided with a corresponding The fixing part 52 .

As shown in Fig. 2 and Fig. 4, when the rotary switch structure 1 is in use, mainly by rotating the rotary member 4, the conduction member 44 arranged at the bottom thereof contacts a plurality of conduction terminals 24 at the bottom of the base 2, and through the contact Different conduction terminals 24 are used to change the conduction current to achieve different conduction effects. Since the plurality of teeth 42 on the outer surface of the bottom side of the rotating member 4 are pressed by the limiting shrapnel 51, the rotation of the rotating member 4 It is a multi-stage rotation mode, and when the rotating member 4 is located on different segments, the conduction terminals 24 touched by the conducting member 44 at the bottom of the rotating member 4 are not the same, so the conducted current also varies. However, the rotary switch structure 1 can not only know the on or off state by pressing the light-emitting part 31 on the device 3, but also can make the rotating part 4 be located on different segments, so that the light-emitting part 31 can be different. Luminous variation in brightness.

In addition, the cover body 5 is mainly snapped onto the two clamping blocks 22 corresponding to the two outer sides of the base 2 through the corresponding fixing parts 52 provided on its two sides, so that the cover body 5 can be firmly arranged on the base 2, and due to the use of The limit elastic piece 51 to press the tooth portion 42 is also extended from the cover body 5, and the limit elastic piece 51 is correspondingly located on both sides of the cover body 5, so when the cover body 5 is firmly installed on the base 2, the position limit In addition to being used to press against the tooth portion 42, the elastic piece 51 is pressed by its corresponding two sides through the elastic force of the limiting elastic piece 51, which also has the effect of increasing the stability of the rotating member 4, and because the limiting elastic piece 51 is formed by the cover body 5 itself Therefore, there is no need to use the known shrapnel as an additional part, and a position for placing the shrapnel must be additionally provided. After the cover body 5 is combined with the base 2, the limiting shrapnel 51 is located and can be pressed to In the correct position of the tooth portion 42, not only the stop elastic piece 51 does not need to be manufactured separately to save costs, but also the processing time for setting the stop elastic piece 51 is eliminated, as shown in FIG. 2 .

The rotary switch structure 1 can not only achieve different conduction effects by rotating, but also can make the light-emitting part 31 on the upper end emit light by pressing the pressing device 3, and achieve different conduction effects, while the transparent part outside the light-emitting part 31 The casing is made of different materials through printing or laser engraving and the degree of exposure of the luminous element 31 to the rotating element 4 is different, so that the luminous element 31 can produce different luminous effects when emitting light. In addition, since the pressing device 3 is installed and positioned on the base The seat 2 is combined by dispensing glue, so if the user only needs the function of rotation, it is not necessary to set the pressing device 3 in the rotary switch structure 1, see Fig. 2 and Fig. 5 .

The conduction member 44 at the bottom of the rotating member 4 and different conduction terminals 24 produce different conduction effects, as shown in Figure 3, mainly because the conduction member 44 is a ring-shaped body, and a plurality of The contact ends 442 are at different circumferential positions, and the plurality of conduction terminals 24 are also distributed on different circumferential positions in sections in addition to the different circumferential positions in design. Therefore, when the rotating member 4 rotates to each segment Finally, since the contact end 442 of the conducting member 44 touches the conduction terminals 24 at different positions, and the resistance value of each conduction terminal 24 is different, that is, the current changes, thereby producing different conduction effects.

The above descriptions are only preferred embodiments of the utility model, and are not intended to limit the protection scope of the utility model. The patent protection scope of the utility model should still be based on the content of the claims.
