Abstract

An electrical power tool may include a housing, a rotating tool that is rotatably attached to the housing, a motor that is positioned in the housing and is capable of rotating the rotating tool, a manipulating portion that is attached to the housing, and an indicator device that is disposed in the housing and is capable of indicating a condition of the electrical power tool. The manipulating portion is positioned to substantially cover the indicator device. The manipulating portion is constructed such that light emitted from the indicator device can be transmitted therethrough.

Claims

1. An electrical power tool, comprising:

a housing;

a rotating tool that is rotatably attached to the housing;

a motor that is positioned in the housing and is capable of rotating the rotating tool;

a manipulating portion that is attached to the housing; and

an indicator device that is disposed in the housing and is capable of indicating a condition of the electrical power tool,

wherein the manipulating portion is positioned to substantially cover the indicator device, and wherein the manipulating portion is constructed such that light emitted from the indicator device can be transmitted therethrough.

2. The electrical power tool as defined in claim 1, wherein the manipulating portion and the indicator device are attached to a circuit board of a circuit device for controlling the motor.

3. The electrical power tool as defined in claim 2, wherein the manipulating portion is partially projected from a slot that is formed in the housing.

4. The electrical power tool as defined in claim 3, wherein the manipulating portion comprises a speed setting dial that is capable of setting rotation speeds of the motor.

5. The electrical power tool as defined in claim 4, wherein the speed setting dial is rotatably attached to the circuit board while an outer peripheral surface thereof is partially projected from the slot.

6. The electrical power tool as defined in claim 4, wherein the speed setting dial is positioned to substantially encircle the indicator device.
