Abstract
A hybrid relay () comprises an electromechanical part () with a movable contact (), a solid state relay () and a control unit () for applying a drive signal (S',S″) to the drivable coil () of the electromechanical part. A method for operating the hybrid relay comprises steps of determining a first minimum voltage (V) for the drive signal above which the movable contact () starts to move away from an open position (P) and a second minimum voltage (V) for the drive signal above which the movable contact () reaches the closed position (P), and a step of shaping a waveform (W) for the drive signal comprising a portion (W) consisting of a vertical segment jumping from zero to the first minimum voltage value, a portion (W) wherein the voltage gradually increases from the first minimum value to the second minimum voltage value, and a portion (W) consisting of another vertical segment jumping from the second minimum voltage value to an upper voltage boundary (V).
