Abstract
The actuation device has nail-shaped contact pins (1), the heads (3) of which project into an ignition chamber (8), with the ends of a resistor wire (6) being attached to the heads (3) of the contact pins (1). The detonator (9) which fills the ignition chamber (8) is a detonator which is free-flowing during the manufacture of the device, which envelopes the heads (3) of the contact pins (1) and the resistor wire (6) and which subsequently solidifies. The contact pins are surrounded by an electrically conductive extension (23) of the housing of the actuation device, so that a spark gap (F) is formed here; to discharge overvoltage, several sparks can flash over this gap simultaneously.
