Abstract: An operation-indication mode switching structure, a circuit, and a method for operating the same are provided. The operation-indication mode switching structure is disposed on a housing of a device, and includes a switching mechanism that is used to switch multiple operation-indication modes. The switching mechanism is selectively connected with one of multiple signal terminals. When the switching mechanism is manipulated to switch to one of the operation-indication modes, a control unit of the device receives an operation-indication mode switching signal generated by the switching mechanism conducting or circuit-shorting one of the multiple signal terminals. A corresponding operation-indication mode that is a covert mode, a stealth mode, or a normal mode can be determined. The control unit is used to control an indication function of the device according to the operation-indication mode that is switched to.
