Abstract

A hand-held device with a holder for a working tool has a sensing mechanism for automatically initiating different operating modes. Different configurations of working tools inserted into the holder can be sensed by sensing elements in the form of balls. The balls cooperate with pivotal levers and a sensor for producing switching signals for initiating a switching operation.
