Abstract

A hand power tool includes a drive unit, an electronic unit, and a switching unit. The switching unit includes at least one actuating element configured to activate and deactivate the drive unit. The switching unit also includes at least one switching element configured to be positioned in at least one first switching position to set at least one first operating mode. The at least one switching element is also configured to be positioned in at least one second switching position to set at least one second operating mode.

First claim

What is claimed is:

1. A hand power tool, comprising:
a drive unit;
an electronic unit; and
a switching unit, including:
at least one actuating element configured to activate and deactivate the drive unit; and
at least one switching element configured to be positioned in at least one first switching position to set at least one first operating mode and configured to be positioned in at least one second switching position to set at least one second operating mode,

wherein at least one stop element is formed on the at least one switching element and is configured to mechanically stop travel of the at least one actuating element when the at least one switching element is positioned in at least one of the at least one first switching position and the at least one second switching position.

2. The hand power tool according to claim 1 , wherein the at least one switching element is configured to be positioned in at least one third switching position to set at least one third operating mode.

3. The hand power tool according to claim 1 , wherein:
the first operating mode includes a normal operation, and
at least one of the at least one second operating mode and the at least one third operating mode includes at least one of an eco operating mode and a boost operating mode.

4. The hand power tool according to claim 1 , wherein the at least one switching element and the at least one actuating element are configured, at least partially, as a single piece.

5. The hand power tool according to claim 1 , wherein the at least one switching element is configured to be locked in at least one of the at least one first switching position and at least one of the at least one second switching position and the at least one third switching position.

6. The hand power tool according to claim 2 , wherein the at least one switching element has at least one latching element configured to lock the switching element in at least one of the at least one first switching position and at least one of the at least one second switching position and the at least one third switching position.

7. The hand power tool according to claim 1 , wherein at least one of the at least one switching element and the at least one actuating element includes a slide switch.

8. The hand power tool according to claim 2 , wherein the at least one stop element is configured to mechanically stop travel of the at least one actuating element when the at least one switching element is positioned in at least one of the at least one first switching position and at least one of the at least one second switching position and the at least one third switching position.

9. The hand power tool according to claim 1 , further comprising a drive unit including at least one EC motor.

10. The hand power tool according to claim 1 , wherein the hand power tool is an angle grinder.

11. A hand power tool, comprising:
a drive unit;
an electronic unit; and
a switching unit, including:
at least one actuating element configured to activate and deactivate the drive unit; and
at least one switching element configured to be positioned in at least one first switching position to set at least one first operating mode, positioned in at least one second switching position to set at least one second operating mode, and positioned in at least one third switching position to set at least one third operating mode,
wherein the at least one switching element has at least one latching element configured to lock the switching element in at least one of the at least one first switching position and at least one of the at least one second switching position and the at least one third switching position.

12. A switching unit of a hand power tool, the switching unit comprising:
at least one actuating element configured to activate and deactivate a drive unit of the hand power tool;
at least one switching element configured to be positioned in at least one first switching position to set at least one first operating mode and configured to be positioned in at least one second switching position to set at least one second operating mode;
an electrical switch;
a converter element coupled to the electrical switch and configured to convert a movement of the at least one actuating element to the electrical switch; and
a locking element configured to mechanically lock the at least one switching element in at least one of the at least one first switching position and the at least one second switching position.
