The invention relates to a gasoline motor powered, hand-operated working machine, which is stopped by short-circuiting an electric circuit (70), said stop device being designed in the form of an electric switch comprising a stop control (11), which can be moved manually between two end positions; a drive position for start of the motor and for motion of the motor, in which drive position said circuit is not short-circuited, and a fixed stop position in which the circuit is short-circuited and the stop control is locked. The characteristic features are that the electric circuit is short-circuited also in a non-locked intermediate position (II) of the stop control, which the stop control must pass, if it is brought all the way from the drive position (I) to the fixed stop position (III), and that a spring (60) is provided to return the stop control to the drive position, if the stop control is moved from the drive position to said intermediate position and then released, implying that the intermediate position is a re-springing stop position of the stop control. |
