  • Patent number: 10796859
    Abstract: A hand-held power tool, in particular an angle grinder, includes a tool receiver, a tool housing, and a drive motor arranged in the tool housing. The drive motor is configured to be switched on and off via an electric On/Off switch for driving the tool receiver. The hand-held power tool also includes an actuating device configured to actuate the On/Off switch. The actuating device has a pivotably mounted actuating element and a pivotably mounted pawl that is configured to be coupled to the actuating element. The pawl is further configured, in a free-running state, to move pivotably relative to the actuating element and, in an actuation state, to exert upon the actuating element an actuating force that actuates the actuating device.
