Circuit arrangement for time-limited signal emission, and use of the circuit arrangement in a warning device

摘要

On the one hand the design, and on the other hand the use, of a circuit arrangement (which consists of resistors, electronic components and a charge capacitor) for time-limited signal emission by means of a transistor are proposed, to be precise the transistor on the one hand can be influenced in a simple manner via a diode and on the other hand itself controls (essentially via a downstream-connected Darlington transistor) an optical and/or acoustic signal transmitter which is used as a warning device, the virtually unavoidable negative interference voltage influences which occur outside the circuit arrangement, in the circuit of the associated voltage source, being blocked via a further diode.
