Pyroelectronic detonator provided with a circuit for shunting an electrothermal bridge

A pyroelectronic detonator includes an electronic circuit for at least controlling the detonator ignition by supplying igniting current to an electrothermal bridge and at least one electronic shunting element directly connected to the bridge, wherein the shunting element is controllable between the closed low-electric resistance state of the shunt and the open high electric resistance state thereof and the electronic circuit controls the states. The shunt is constructed in such a way that it can be monostable and bistable.
