The results of an experimental study of the influence of switching conditions: the magnitude of currents and magnetic field sources of switching devices on the characteristics of magnetically controlled contacts are presented. To determine the necessary parameters, the transfer characteristics obtained due to the inclusion of the studied reed contact according to the scheme of a classical four-pole were used. The analysis of a set of experimental conditions determining the magnitude and spread of the resistance values of magnetically controlled contacts during repeated switching, as well as the influence of the magnetic field sources of switching devices on the reproducibility of parameters calculated according to the developed program: the shape index and the spectral power density of LF noise .The experimental conditions under which the maximum reproducibility of the results is achieved are revealed. The purpose of this work is to study the factors affecting the spread of the resistance value and the parameters of the LF noise spectra during multiple repeated switching of the reed contact using a magnetic field from different sources.
Key words: : LF noise, magnetically controlled contacts, measuring installation, contact resistance, power spectral density
