Abstract
A shaft lock arrangement having a shaft lock slidably mounted in the housing of a power tool. The shaft lock has a keyhole-shaped aperture having a circular portion circumscribing the output shaft of the power tool when the shaft lock is in a RUN position and a rectangular portion, the sides of which straddle flat portions of the output shaft preventing the output shaft from rotating when the shaft lock is in the LOCKED position. The shaft lock further has a run detent resiliently engaged by a toggle of a cut-out switch to hold the shaft lock in the RUN position and a lock detent resiliently engaged by the toggle of the cut-out switch to hold the shaft lock in the LOCKED position. The cut-out switch prevents electrical power from applied to the motor of the power tool when the shaft of the power tool is locked by the shaft lock.
