Embodiment Construction

[0015] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0016] The split state structure of the embodiment of the present invention is as follows Figure 1-9 As shown, the appearance of the assembled state is as follows Figure 10 , 11 shown.

[0017] Such as figure 1 , 2 In this embodiment, the rotary switch includes a basic fixed assembly 1 and a rotary assembly 2. The rotary assembly 2 includes a rotary cap 21 at the upper end and a rotary post 22 at the lower end. The rotary cap 21 and the rotary post 22 are integrally structured. It is completed in one piece during mold opening and injection molding. The inner wall of the fixed assembly 1 is symmetrically provided with slots 12 along the circumferential direction. Two fixed conductive sheets 13 are arranged on the inner bottom of the fixed assembly 1. These two fixed conductive sheets 13 are respectively connected with two switch pins 14....

Abstract

The invention discloses a rotary switch, including a fixed component and a rotary component, a lower end of the fixed component is provided with switch feet, side walls of the fixed component and the rotary component are provided with corresponding block portions connected mutually; an inner side of the fixed component bottom is provided with fixed conductive strip connected with pair of switch feet, an lower end of the rotary component is provided with movable conductive strip rotating along the rotary component; the block portion includes a groove or a slot arranged on the inner wall circumference of the fixed component and a barb arranged at a corresponding position of the rotary component outer wall; the movable conductive strip is an arc-shaped shrapnel, its middle is provided with a hole, the movable conductive strip is riveted to a prominency locating on a lower end of the rotary component through the hole. Comparing with the present technology, the rotary switch has a simple structure, a low processing cost, its volume is capable of being made smaller and it is capable of adapting various situation requirements; the rotary switch is provided with a plurality of conjunction structures, which gives attention to the conveniency and hand handle of the switching operation.

Description

technical field [0001] The invention relates to an electronic component, in particular to a rotary switch. Background technique [0002] At present, the rotary switch is mostly provided with a plurality of fixed contacts on a switch base, and the rotary operation knob used as a switch switch is installed on the switch base, and a contact piece that rotates with the knob is installed on the rotary operation knob, so that the contact piece Contact with the fixed contact on the switch base to realize the on-off connection of the line. This kind of rotary switch has a plurality of recessed structures preset on the outer periphery of the knob, and ratchet structures such as leaf springs are arranged in the recessed structures. [0003] With the development of technology, the scope of application of rotary switches is more and more extensive, and the types are also ever-changing. People are constantly pursuing its miniaturization and simple structure, and at the same time, they a...
