Two-piece capsule trigger unit for initiating pyrotechnic elements

The invention relates to a trigger unit for initiating pyrotechnic elements. The invention relates to trigger units for initiating pyrotechnic elements which usually consist of a switch and control unit, ignition means and an ignition charge body. Said switch and control element is triggered by way of an electric coupling via a line in order to initiate ignition. The line for the electric coupling and the dimensions of the switch and control element which are usually accommodated in an IC housing complicate the design and the automatic assembly of the trigger units. According to the invention, the switch and control element () is surrounded by a first shell (). Said first shell () is connected to a second shell () which contains the ignition charge body (). The invention is further characterized in that the ignition means () dip into said second shell ().
