Abstract

An electronic device for triggering safety devices 10 comprises a firing element ZP which is connected in series to a capacitor ZK. The firing element ZP is acted upon by currents from controllable current sources IQ1, IQ2, which, in accordance with an output signal of a sensor S, are triggered by an evaluation circuit AS.
