Abstract (en)
[origin: WO2009021667A1] The invention relates to an internal combustion engine valve drive switching device having a switching unit (36, 36a). It is proposed that the switching unit (36, 36a) has an implementation unit (38, 38a) which is provided to implement a first switching process on the basis of at least one signal, and thereafter, to implement a second switching process independently of an electronic evaluation.
