A circuit for switching on a partial circuit includes a first switching element (T1), a second switching element (T2 to T6), an activation circuit for the first switching element, a first diode (D1), a second diode (D2), and a third diode (D3). During operation, when the partial circuit is being switched on, first switching element (T1) is activated and second switching element (T2 to T6) is assigned no activity. The activation circuit for the first switching element (T1) includes a storage capacitor (C1) and a DIAC coupled to a control electrode of the first switching element (T1). First diode (D1), second diode (D2), and third diode (D3) are arranged such that stored energy in storage capacitor (C1) is more effectively utilized for activating the first switching element (T1), thus allowing use of a smaller capacitance for the storage capacitor (C1).
