Shaking and overshifting will not occur. The positioning curved surface at the top of the vertical arm of the elastic arm cooperates with the three positioning grooves on the inner wall of the lower cover of the switch to move, so that the knob-type strobe switch can get a good feel, and the elastic arm can provide sufficient and suitable balanced damping force during the movement , so that the control force of the knob-type strobe switch is uniform and easy to control. The switch upper cover is installed on the balance body of the strobe switch through the upper positioning post and the lower positioning post, and is fixed in the four upper cover fixing slots through four upper cover fixing clips, which not only plays a fixed role, but also reduces the need for switching on the switch. Axial wobble when the cover is rotated.
工作原理:通过旋转开关上盖,开关上盖就会通过上定位柱和下定位柱带动选通开关平衡本体一起转动,实现选通档位功能。在开关上盖和选通开关平衡本体的旋转运动过程中,当旋转至起始档位,止动位被外限位柱限位;当旋转至终止档位,限位槽被内限位柱限位,使得开关的圆周运动得到有效地停止,不会产生过档现象。 Working principle: By rotating the upper cover of the switch, the upper cover of the switch will drive the balance body of the gating switch to rotate together through the upper positioning post and the lower positioning post to realize the gating gear function. During the rotation movement of the upper cover of the switch and the balance body of the strobe switch, when the rotation reaches the initial position, the stop position is limited by the outer limit column; when the rotation reaches the end position, the limit slot is limited by the inner limit column. Limit, so that the circular movement of the switch is effectively stopped, and no over-shift phenomenon will occur.

These advantages are not available in traditional rotary switches. The present invention can adjust the length of the two elastic arms according to the actual size of the upper cover of the switch, and the elastic arms can provide sufficient and suitable balanced damping force. As a result, when the switch is operated in a circular motion, the shaking amount is greatly reduced, and the operating force is uniform and smooth. The gears are clear and the control force meets the design requirements. The present invention is designed as a symmetrical structure, and can be installed in two directions of 0 degree or 180 degree during assembly, and is simple, reliable and practical.
因此,本发明具有作圆周运动操作时晃动量大幅减少、操作力均匀且档位清晰、集成度高、加工容易、安装快捷、手感好、简单可靠、实用性强、低成本、高性能的优点。 Therefore, the present invention has the advantages of greatly reduced shaking during circular motion operation, uniform operating force and clear gear positions, high integration, easy processing, quick installation, good hand feeling, simple and reliable, strong practicability, low cost, and high performance. .
