Abstract: A switching device for an electric tool includes: an output shaft unit disposed in an outer casing, having an output shaft, a movable ratchet wheel mounted such that the movable ratchet wheel is movable axially along the output shaft and is non-rotatable therewith; a fixed ratchet unit having a fixed ratchet wheel sleeved around the output shaft and having ratchet teeth for meshing with ratchet teeth of the movable ratchet wheel; and a function switch unit having a switch ring mounted rotatably on the casing. Rotation of the switch ring about its axis results in rotation of pawls within the switch ring, thereby driving the pawls about its pivot points and meshing and/or non-meshing of the pawls with external ratchet teeth of the fixed ratchet wheel, thereby switching the output shaft among a continuous rotation, rotation in a single direction and simultaneously providing an axial impact during the rotation.

Abstract: A method for managing an alternating current adaptor system is disclosed. A direct current voltage is received at a high impedance power delivery network from a primary side of an alternating current adaptor system. An isolated voltage is output from the high impedance power delivery network to components of a secondary side of the alternating current adaptor system. A transition in a power state identification of an information handling system associated with the alternating current adaptor system is detected. An output voltage level of the alternating current adaptor system is alternated in response to the transition in the power state identification of the information handling system.
