Definitions
- the magnetic core has an effective core surface adjoining the trigger coil at the end.
- the advantage here is that no separate or integrated magnetic core has to be attached or shaped. Both the material required for this and any attachment can thus be saved.

- a pair of wings preferably adjoins the magnetic core, as a result of which the electromagnetic principle on which the trigger is based can be advantageously influenced.
- the cylinder is advantageously designed as a deep-drawn part. In this way, a cost-saving shortening of the production cycles can be achieved.
- the base body forms a leg with its free end, which has a recess arranged therein, which also serves to guide the release anchor. This is a useful and parts-reduced storage. An extension for electrical connection to the is preferred
