Abstract
An electrical hand-held power tool includes a non-contacting electrical manual control switch (3) having an operating element (4) and a sensor switch (5), a pivotable carrier (6) which carries a switching element (13) and which is manually controlled by the operating element (4) of the manually control switch (3), the sensor switch (5) being connected with the carrier (6) vibration-free, and pivot transmitting device (7) axially displaceable along the vibration axis A) of a vibrating assembly (2) of the power tool relative to the operating element (4) for pivoting the carrier (6) in response to actuation of the operating element (4).
Claims10
An electrical hand-held power tool, comprising a housing (11);
- an assembly (2) arranged in the housing (11) and vibrating along a vibration axis (A), the housing (11) being isolated from the vibrations of the vibrating assembly (2);
- a non-contacting electrical manual control switch (3) having operating means (4) and a sensor switch (5);
- switching means (13) for displacing the control switch (3) between ON/OFF positions thereof;
- a pivotable switching means carrier (6) which is manually controlled by the operating means (4) of the manually control switch (3) and a pivot axis of which is oriented parallel to the vibration axis (A) of the vibrating assembly (2), the sensor switch (5) being connected with the switching means carrier (6) vibration-free;
- and pivot transmitting means (7) axially displaceable along the vibration axis (A) of the vibrating assembly (2) relative to the operating means (4) for pivoting the switching means carrier (6) in response to actuation of the operating means (4), the pivot transmitting means (7) having a first element (8) associating with the vibrating assembly (2) and a second element (9) associated with the housing (9).
