A power tool includes a housing, an electric motor, an end effector coupled to the motor, a control circuit configured to control electrical power delivery to the motor, and a switch for selectively providing electrical power to the control circuit. The switch includes an elongated outer casing having at least a portion exterior of the housing. The casing is linearly moveable in a first linear direction generally transverse to a longitudinal axis of the housing. A linkage is disposed inside of the housing and coupled to the casing such that linear movement of the casing in the first direction causes linear movement of the linkage in a second direction generally transverse to the first direction. An electrical switch is disposed inside the housing and coupled to the linkage such that linear movement of the linkage in the second direction causes activation of the electrical switch.

Power tool having switch and rotary input control

A power tool includes an output shaft configured to rotate about a longitudinal axis, a motor drivably connected to the output shaft to impart rotary motions thereto, and a rotational motion sensor spatially separated from the output shaft and operable to determine the user-imparted rotational motion of the power tool with respect to the longitudinal axis. A controller is electrically connected to the rotational motion sensor and the motor. The controller determines angular velocity of the power tool about the axis, rotational displacement of the power tool about the axis, and/or a direction of the rotational displacement using input from the rotational motion sensor. The controller then controls the motor according to the angular velocity, the rotational displacement, and/or the direction of the rotational displacement.
