The main electrical characteristics (current - voltage characteristic, differential conductivity and
electron density) of Au - C14H9 - Au nanoswitch have been calculated within the framework of the Hückel model combined with the method of nonequilibrium Green's functions. Based on the analysis of the results, we can say that the Au - C14H9 - Au nanoswitch can be created, which operates reliably under the influence of noise signals. The amplitude of this nanoswitch is 1,03 nA, therefore the presence of fluctuation current (noise) with amplitude of about 1 nA in electronic circuit has a directly influence on nanoswitch operation. It was revealed that the particularities of electric
characteristics of considered nanostructures allows to exclude the error operation of nanoswitching device by selection of optimal value of threshold current ±145 nA, as the oscillation of current in the interval of voltage -3÷-1.2 V can be neglected. In this way, nano commutation device operation modes are determined. These results will provide an important
contribution to the development of promising new switching devices for nanoelectronics.
