The wavelength selecting switch is provided with an optical system, a switching attenuation unit, a switching attenuation control unit, a gravity acceleration sensor and a microprocessor, which are arranged in a main body, wherein the switching attenuation control unit is connected with the switching attenuation unit; a signal input end of the microprocessor is connected with the gravity acceleration sensor; and a signal output end of the microprocessor is connected with the signal input end of the switching attenuation control unit. The method comprises the following steps: sending a signal to the microprocessor by the gravity acceleration sensor; treating, storing, comparing and judging the signal by the microprocessor and outputting acceleration values after being changed in all directions; and controlling the switching attenuation unit by the switching attenuation control unit according to the received values. The wavelength selecting switch provided by the invention is simple in structure, low in cost and easily realized. The wavelength selecting switch can be applied to any optical communication device which is similar to the wavelength selecting switch, has a built-in switching attenuation unit and is based on a free space platform optical system. The problem of related index change, such as insertion loss, and the like, caused by different placing states or running states, is efficiently solved by using the wavelength selecting switch.
