The present invention relates to a circuit arrangement for switching on a partial circuit arrangement with a first switching element (T1), the first switching element (T1) having a control electrode and a reference electrode, which is connected to a reference potential; a partial circuit arrangement, the first switching element (T1) having to be activated when the partial switching arrangement is being switched on; at least one second switching element (T2 to T6), which is required for the operation of the circuit arrangement after the partial circuit arrangement has been switched on, but which is assigned no activity when the partial circuit arrangement is being switched on, the at least one second switching element (T2 to T6) having a control electrode and a reference electrode, which is connected to the reference potential; an activation circuit for the first switching element (T1), the activation circuit comprising a storage capacitor (C1) which, to activate the first switching element (T1), is connected via a DIAC to the control electrode of the first switching element (T1); and a first diode (D1) which is arranged between the reference potential and the storage capacitor (C1) in such a way that it is made possible for a current to flow to activate the first switching element (T1); in series with the first diode (D1), on the side of the first diode (D1) facing away from the reference potential, a second diode (D2) being arranged in the same orientation as the first diode (D1), the junction between the first and the second diode (D1, D2) being connected to the control electrode of the at least one second switching element (T2 to T6) and, in series in a connection between the control electrode of the second switching element (T2 to T6) and the reference potential, in addition to the second diode (D2), at least one third diode (D3) being connected in the same orientation as the second diode (D2).
