Abstract

Oppfinnelsen vedrører en pyroelektronisk detonator (1) omfattende en elektronisk krets for i det minste å styre detonatorantenningen ved å levere antenningsstrøm til en elektrotermisk bro (4) og minst én elektronisk shuntinnretning (7) direkte forbundet til nevnte bro (4), der nevnte broinnretning (7) er styrbar mellom lukket lavelektrisk motstands stand av shunten og den åpne høyelektriske motstandstilstanden av denne og den elektroniske kretsen (2) kontrollerer nevnte tilstander. Shunten er konstruert på en slik m'ate at den kan være monostabil eller bistabil.
