PROBLEM TO BE SOLVED: To obtain a hand-held power tool device having a non-contact electric manual switch disposed at a handle and insensitive to vibration. SOLUTION: In the hand-held power tool device comprising at least one handle 3 projecting laterally, insulating vibration, and rotatable around a handle pivot point G, and the manual switch 4 having an operating means 5 disposed at the handle 3, the operating means 5 is switchably connected to at least one sensor switch 8 disposed in the vicinity of the handle pivot point G in a structural unit 2 via a switching rod 7, having a switch means 6, displacable, and rotatably attached to a switch pivot point S spaced from the handle pivot point G so that it is separated from a vibration axis A, in the handle 3. Preferably, the switch pivot point S is disposed at the position which is 1/3 of the distance between the handle pivot point G and the operating means 5, a sensor switch 8 comprises a hall element and the switch means comprises a permanent magnet.
