To prevent spurious responses of a semiconductor switching element used in triggered magneto-type semiconductor ignition-switching systems, primarily due to noise signals introduced by the magneto, the control circuit for the ignition system includes a common, parallel connected R/C compensation circuit, connected through decoupling diodes to the ignition trigger pulse sources for the respective cylinders and the grounded main terminal of the switching element to supply a compensating voltage which suppresses noise voltages which increases with increasing speed of the internal combustion engine and thus dynamically compensates for generated noise pulses.
