Beschreibung
Zusammenfassung:	This invention relates to protective circuitry ( 12 ) for electrical initiation elements ( 10 ) and finds utility in preventing inadvertent functioning of electrical bridge-initiation elements, such as semiconductor bridges (SCBs), bridgewires, etc., by transient environmental electrical signals. The protective circuitry ( 12 ) of this invention comprises a timer portion ( 14 ) and a clamping portion ( 16 ) and is designed to divert from the electrical initiation element ( 10 ) at least a portion of an electrical signal received at the input nodes ( 10 a , 10 b) thereof for a suitable time interval that corresponds to the duration of an expected transient signal, which is typically significantly smaller than the duration of a proper initiation signal.
