Abstract

A control lever for a power tool of a type which is normally held in an operator's hand during use and has a generally cylindrical body and an on/off switch. The switch is operated by an arm of the which is pivotally connected at or adjacent one end to the body. The arm is biased towards a first position in which the switch is `off` and is pivotably movable to a second position in which the switch is `on`. A latch member is mounted for pivotal movement relative to the body and biased by a torsion spring towards a first position in which, when the arm is also in its first position, the latch member engages the arm to prevent unintentional movement of the arm to its second position. The latch member has a thumb engageable section which extends through a slot or aperture in the arm whereby an operator can pivot the latch member towards a second position thus permitting the arm to be moved towards its second position to turn the switch `on`.
