Abstract

An electrical hand-held power tool includes an assembly ( 2 ) vibrating along a vibration axis (A) during operation of the power tool, at least one, transversely projecting, vibration-decoupled pivotal side handle ( 3 ), a manual switch ( 4 ) having an actuation element ( 5 ) arranged in the side handle ( 3 ) and switchingly connectable with at least one sensor switch ( 8 ) which is located in the assembly ( 2 ) in vicinity of the handle pivot point (G), by a switching rod ( 7 ) having a switching element ( 6 ) and being pivotally supported on the side handle at a switching pivot point (S) spaced from the handle pivot point (G) and from the vibration axis (A).

Claims (4)

1. An electrical hand-held power tool, comprising an assembly ( 2 ) set in vibration along a vibration axis (A) during operation of the power tool; at least one, transversely projecting, vibration-decoupled side handle ( 3 ) pivotal about a handle pivot point (G); a manual switch ( 4 ) having actuation means ( 5 ) arranged in the side handle ( 3 ); a displaceable switching rod ( 7 ) for switchingly connecting the actuation means ( 5 ) with at least one sensor switch ( 8 ) located in the assembly in vicinity of the handle pivot point (G), the switching rod ( 7 ) having switching means ( 6 ) and being pivotally supported on the side handle at a switching pivot point (S) spaced from the handle pivot point (G) and from the vibration axis (A).

2. An electrical hand-held power tool according to claim 1 , wherein the switching pivot point (S) is located in a middle third between the handle pivot point (G) and the actuation means ( 5 ).

3. An electrical hand-held power tool according to claim 1 , wherein the sensor switch ( 8 ) is formed as a Hall sensor switch, and the switching means ( 6 ) is formed as a permanent magnet.

4. An electrical hand-held power tool according to claim 1 further comprising a further sensor switch ( 8 ) associated with the switching means ( 6 ), the at least one sensor switch ( 8 ) and the further sensor switch ( 8 ) being arranged on opposite sides of the switching means ( 6 ) and being spaced therefrom in a direction transverse to a switching direction.
