一种旋钮型切换开关

本发明属于转换开关领域，提供了一种旋钮型档位开关，包括旋转轴、至少一个公共极导电片、多个档位导电片及至少一个切换组件，切换组件具有公共极咬合部和档位咬合部，随着旋转轴的转动，带动切换组件同步转动，在转动的过程中，公共极导电片始终与对应的公共极咬合部相咬合，而档位咬合部与不同的档位导电片相咬合，从而使公共极导电片与不同的档位导电片通过切换组件形成电流通路。而公共极导电片与电路板上的总输入电路电连接，档位导电片与电路板上的切换电路电连接，因此，一个电路输入总线能够与多个切换电路电连接，从而实现多档位切换。本发明提供的旋钮型转换开关的结构简单，利于大规模生产与推广。 The invention belongs to the change-over switch field, and provides a knob type gear switch. The gear switch comprises a rotating shaft, at least one common pole conducting sheet, a plurality of gearconducting sheets and at least one switching component. The switching component has a common pole occlusion portion and a gear occlusion portion. The switching component is driven to rotate synchronously along with rotation of the rotating shaft. In a rotating process, the common pole conducting sheet is occluded with the corresponding common pole occlusion portion all the time, the gear occlusion portion is occluded with the different gear conducting sheets, and the common pole conducting sheet and the different gear conducting sheets
