Abstract
The invention relates to an electrically powered hand tool which comprises a device for providing tactile feedback to an operator of the tool. The tool further comprises a user-operated trigger for activating the working member of the tool. The tactile feedback provided by the tool alerts the operator about the activation status of the tool. More specifically, the operator is provided with an indication that the power to the tool is ON. The tactile feedback is provided at least from the time when the power to the tool is turned ON to the point in time when the trigger is pulled to activate the working member of the tool.
