Abstract

A trigger device (10) for activating an action by detection of a predetermined sequence, the sequence being given by characteristic changes in a natural magnetic field, and where the trigger device (10) comprises one or more magnetic field sensors and means for detecting and interpreting said changes in a natural magnetic field. The trigger device (10) is constituted further by an independent unit with no moving parts which is signal- connected and/or mechanically connected to one or more device that are to be activated to perform an action. The device can be implemented to activate and operate different types of tools.
