The paper concerns the problem of heterogeneous triggering of button interfaces located in close proximity on the same control panel. The paper analyzes and classifies the existing hardware solutions, as well as its own methodology for solving this problem. An experiment showing the effectiveness of the proposed design is presented. The relevance of the work is confirmed by the degree of use of button interfaces in various spheres of human life. Button interfaces are widespread, as evidenced by their popularity in control panels of electronic industry devices. Due to the increase in production technology, and with it the interfaces of control panels, more and more cases of erroneous operator commands caused by the problem of differently triggered buttons from the tactile pressure, for this reason the work of the company was disrupted or stopped. The current state of this situation requires the creation of a solution to the problem of user interaction with button interfaces of different manufacturers, which have different types of triggering. The object of the study was to develop a solution for leveling of different types of triggering, rattle and noise suppression for button interfaces of different purposes used in unified control panels. Conduct experimental studies to validate the effectiveness of the proposed. The main methods used were analysis, synthesis, classification description, experiment setting, formalization, and comparison. As a result, a hardware solution has been developed, the correctness of its operation, as well as its high efficiency in reducing the negative impact of the problem of user interaction with button interfaces that have different types of triggering, is confirmed by the conducted experiment. The developed hardware solution allows to combine several control panels into a single panel and at the same time reduce the chance of operator error, because it brings different types of presses to a single output signal. It also levels the influence of rattle and interference. #CSOC1120.
