Operation-indication mode switching structure, circuit and method for operating the same

A device, comprising:

• a control unit;
• a main switch for activating the device to start or stop recording;
• a wheel switch disposed around a circumference of the main switch and rotatable to select a category from a plurality of categories for categorizing a video clip captured by the device;
• and
• a mode-switching switch disposed at a circumference of the wheel switch and configured to move along a predefined arc segment of the circumference of the wheel switch, wherein the mode-switching switch is electrically connected with the control unit, the mode-switching switch is used to switch multiple operation-indication modes of the device, the mode-switching switch is selectively connected with one of multiple signal terminals, and the multiple signal terminals are connected with the control unit of the device;
• wherein the control unit receives an operation-indication mode switching signal generated by one of the multiple signal terminals conducted or short-circuited by the mode-switching switch, the operation-indication mode switching signal corresponds to one of the multiple operation-indication modes, the control unit controls multiple indication functions of the device according to one of the multiple operation-indication modes to be switched, and at least one of the multiple indication functions controlled by the control unit based upon the one of the multiple operation-indication modes to be switched to is a muting of sound originating from a speaker.

An operating method for an operation-indication mode switching circuit, wherein the operation-indication mode switching circuit is disposed in a device, and the operating method includes:

• during an operation of the device, turning on multiple operation-indication functions by using a control unit;
• receiving an operation-indication mode switching signal based upon a position of a mode-switching switch disposed at a circumference of a wheel switch configured to be rotatable to select a category from a plurality of categories of events and disposed at a circumference of a main switch configured to be pressed to start and/or stop recording of a recording device associated with the operation-indication mode switching circuit;
• determining a corresponding one of multiple operation-indication modes when the control unit receives the operation-indication mode switching signal;
• and
• turning on or off one or more of the multiple operation-indication functions according to the corresponding one of the multiple operation-indication modes.
