An integrated electronic switch includes an input unit and a circuit board. The input unit is configured to receive a drive signal output by a user. A sensing module for sensing the drive signal transmitted from the input unit, and a control module electrically connected to the sensing module are disposed on the circuit board, where the sensing module and the control module are disposed on a first side surface of the circuit board.

A battery pack is provided including a body having a first wall forming a first face from which a connection port extends for connection to a power tool or a charger, and a second wall forming a substantially planar second face. A finger notch recessed in the second face extends along an elongate axis perpendicular to a longitudinal axis of the body.

Trigger activated tools are provided that have one or more activation lockouts. The activation lockouts include electrical resets, variable position lockouts, mechanical lockouts, shield lockouts, and any combinations thereof.

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. The lock actuator is biased into the unlocked position while the battery is positioned in the receptacle.

A trigger switch includes a housing including a casing; a trigger coupled to the housing to be capable of approaching and separating from the housing; a contact mechanism; a first terminal extending from outside of the housing to the casing; and a second terminal extending from outside of the housing to the casing and including a plate surface facing a plate surface of the first terminal. A first wire connection portion capable of connecting a conductor portion of a first wire is provided to an end of the first terminal located outside of the housing in an extending direction of the first terminal, and a second wire connection portion capable of connecting a conductor portion of a second wire is provided to an end of the second terminal located outside of the housing in an extending direction of the second terminal.

Trigger activated tools are provided that have one or more activation lockouts. The activation lockouts include electrical resets, variable position lockouts, mechanical lockouts, shield lockouts, and any combinations thereof.

A method is provided for identifying a battery pack that is operably coupled to a battery charger. The method comprises: measuring voltage at a plurality of designated terminals of a first battery pack while the battery pack is coupled to the battery charger; determining how many of the designated terminals are connected to a reference voltage, such as battery positive; and identifying an attribute of the battery pack based on how many of the designated terminals are connected to the reference voltage.
