Abstract: A power tool includes an electric motor, an output member selectively driven by the electric motor and a battery receptacle configured to receive a battery. The power tool also includes a switch trigger moveable between a first position and a second position. The switch trigger inhibits electrical communication between the battery and the electric motor while the switch trigger is in the first position. The switch trigger operates a switch to provide electrical communication between the electric motor and the battery while the switch trigger is in the second position. A lock actuator prevents movement of the switch trigger to the second position while the lock actuator is in a locked position, and the lock actuator permits movement of the switch trigger to the second position while in an unlocked position.

Abstract: An illuminated keyswitch structure with an illuminating module includes a base plate, a drive circuit board under the base plate, a spacer between the drive circuit board and the base plate, and a light-emitting part on the circuit board. The spacer has a through hole communicating with an opening of the base plate in a vertical direction. The light-emitting part is located in the through hole, and falls within a projection of the opening in the vertical direction. The light-emitting part has a top surface that is lower than or equal to a bottom surface of the base plate in the vertical direction. The structure of the illuminated keyswitch structure around the light-emitting part can keep flat by the spacer. The spacer can prevent the light-emitting part from structurally entering the opening, avoiding structural interference between the light-emitting part and other components above the base plate.

Abstract: The resin molded article is molded by using an electrode sheet as an insert in a state where one surface of the electrode sheet is closely attached to an inner surface which serves as the inner side of the operation surface. The electrode sheet is formed by using, as a base material, a thermoplastic synthetic resin sheet which outputs an electrical signal according to the amount of change of electrostatic capacitance generated by a contact operation with respect to the operation surface. At least a whole or a part of the inner surface is formed in a three-dimensionally curved surface, and a passage is formed in the electrode sheet so as to allow a molten resin following in through a gate formed in a die which comes into contact with the other surface of the electrode sheet during molding to pass toward one surface side of the electrode sheet.
