Abstract

An electrically operable machine tool, in particular an electrically operable angle grinder, includes at least one handle housing, and at least one switching unit. The at least one switching unit has at least one operating element mounted on one side of the at least one handle housing which faces a palm surface of a user'"'"'s hand when the handle housing is gripped for proper manipulation.

Claims

1. An electrically operable power tool, comprising:

at least one handle housing; and

at least one switching unit, which has at least one operating element mounted on a side of the at least one handle housing that faces toward an inner surface of an operator'"'"'s hand, when the at least one handle housing is gripped for proper manipulation.

2. The electrically operable power tool as claimed in claim 1, further comprising at least one output housing (22), wherein the at least one operating element, in each operating state, is positioned on a side of the at least one handle housing that is different from a further side of the at least one handle housing that faces toward an output side of the at least one output housing.

3. The electrically operable power tool as claimed in claim 1, wherein the at least one operating element is mounted so as to be pivotable about a pivot axis that is located outside of an operating surface region of the at least one operating element.

4. The electrically operable power tool as claimed in claim 3, wherein the pivot axis, as viewed along a direction of longitudinal extent of the at least one operating element, is spaced apart relative to an operating surface of the at least one operating element.

5. The electrically operable power tool as claimed in claim 3, wherein the pivot axis is located at an end of the at least one operating element that faces toward a connecting region of the at least one handle housing.

6. The electrically operable power tool as claimed in claim 3, wherein the pivot axis is located at an end of the at least one operating element that faces away from a connecting region of the at least one handle housing.

7. The electrically operable power tool at least as claimed in claim 1, wherein the at least one operating element is mounted in a translationally movable manner.

8. The electrically operable power tool as claimed in claim 7, wherein a movement axis of the at least one operating element runs at least substantially transversely in relation to a direction of longitudinal extent of the at least one handle housing.

9. The electrically operable power tool as claimed in claim 1, wherein the at least one operating element is configured such that after an actuation, an operating surface of the at least one operating element is at least substantially flush with an outer surface of the at least one handle housing.

10. The electrically operable power tool as claimed in claim 1, further comprising at least one switch-on inhibitor unit, configured to avoid a movement of the at least one operating element resulting from an unintentional actuation of the at least one operating element.

11. The electrically operable power tool as claimed in claim 10, wherein the switch-on inhibitor unit has at least one release element, which comprises an actuating region that is located, at least partially, laterally next to an operating surface of the at least one operating element.

12. The electrically operable power tool as claimed in claim 1, wherein the at least one operating element has a maximum longitudinal extent that corresponds to at least 60% of a maximum longitudinal extent of a stem-type grip region of the at least one handle housing.

13. The electrically operable power tool as claimed in claim 1, wherein the at least one operating element has a maximum transverse extent that corresponds to at least 60% of a maximum transverse extent of a stem-type grip region of the at least one handle housing.

14. A power tool switching device of a power tool that has at least one handle housing, the power tool switching device comprising at least one switching unit which has at least one operating element configured to be mounted on a side of the at least one handle housing that faces toward an inner surface of an operator'"'"'s hand, when the at least one handle housing is gripped for proper manipulation.
