Description

Technical Field

[0001] This utility model relates to the field of rotary mute switches, and in particular to a combined rotary mute switch. Background Technology

[0002] A rotary switch is a type of switch that controls the on / off state of a circuit by rotating it. A rotary switch typically consists of a knob, contacts, and a spring. When the knob is rotated, the contacts move accordingly, thereby changing the connection state of the circuit and controlling the power supply. Rotary switches are usually used by rotating the knob, which also makes them quiet.

[0003] There are various types of rotary switches, including combination rotary switches. Combination rotary switches are usually connected by multiple housing segments, with the knob and electronic components placed inside the housing. However, the multiple housing segments of a rotary switch are usually fixed by fastening them together in pairs. If it is necessary to inspect the inside of the rotary switch, each housing segment needs to be disassembled, which is cumbersome. Therefore, it is necessary to fix the multiple housing segments of a combination rotary switch in a unified manner. Utility Model Content

[0035] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0036] This utility model provides, for example Figure 1-3 The illustrated combined rotary mute switch includes a first housing 1 with a second housing 2 slidably sleeved on its side. Sealing cylinders are provided between the first housing 1, the second housing 2, and the third housing 3 for sealed interlocking connection. The third housing 3 is slidably sleeved inside the second housing 2, and a knob 4 is rotatably mounted inside the third housing 3. A connecting mechanism 5 is disposed outside the second housing 2 and is used to lock the relative positions of the first housing 1, the second housing 2, and the third housing 3 to uniformly fix the first housing 1, the second housing 2, and the third housing 3.

[0037] Furthermore, the connecting mechanism 5 includes a first frame 51, a second frame 52, a support plate 56, a locking member, and a connecting member. Both the first frame 51 and the second frame 52 are L-shaped. The first frame 51 is convenient to connect with the second frame 52, which in turn facilitates the close connection between the first housing 1 and the second housing 2. The support plate 56 facilitates the sliding of the limiting plate 57 on it, making it easy to provide sliding support for the limiting plate 57. The first frame 51 is fixedly connected to the outside of the first housing 1, and the second frame 52 is fixedly connected to the side of the first frame 51. The support plate 56 is disposed on the side of the second frame 52. The locking member is disposed on the support plate 56 and is used to lock the relative position of the second frame 52 and the support plate 56. The connecting member is located on the side of the support plate 56 and is used to support the support plate 56.

[0038] Furthermore, the connecting mechanism 5 also includes a positioning post 53, a positioning groove, and an assembly post 55. The positioning post 53 is useful for positioning the second frame 52 to increase connection stability. The assembly post 55 is useful for positioning the second frame 52. The positioning post 53 is fixedly connected to the outside of the second housing 2. The positioning groove is opened on the second frame 52.
