Circuit arrangement for identifying switch-on sequences for an on/off switch

摘要: The invention relates to a circuit arrangement for identifying switch-on sequences an on/off switch, with first flip-flop (30) outputting state signal, wherein capacitor (C1) is charged by voltage supply (3) via diode (D1) and charging resistor (R3) charge time constant (1) switch when the latter switched on, this fed second (C2) applied switching input of (D2), output (A1) said then corresponding signal evaluation, wherein, off, discharged again discharge defined (2). likewise method generating on basis time-dependent actuation having steps of: - generation curve dependency differentiation pulse, application pulse one or more threshold value elements, resultant storage elements representing signal.
