Abstract
An inductive ignition device for spark plugs of an internal combustion engine is having at least one activation circuit for at least one ignition coil and having at least one spark plug. A high-voltage switch associated with the at least one spark plug is brought by a first activation signal of the activation circuit into a conductive, switched-on state. In the switched-on state, the high-voltage switch has passing through it the spark current (I.sub.2) of the at least one spark plug (3; 3a to 3n), and which is designed so that without further activation it remains in the conductive state until the spark current falls below a certain value (holding current).
