资源简介：
A control assembly for selectively controlling actuation of an electric motor arranged to power a hand-held power tool based on combined performance of two dissimilar operator actions and a hand-held power tool including such a control assembly. A switch member may be closed responsive to an enabling action including a first of the two dissimilar operator actions. A throttle control member becomes operable responsive to actuation of the throttle control member past a first movement threshold， i.e. a second dissimilar operator action， while the switch member is in the actuated state. The throttle control member remains repeatedly operable above a second movement threshold， even if the switch member is opened. Actuation of the throttle control member to below the second movement threshold will render the throttle control member non-operable until renewed combined performance of the first and second dissimilar operator actions.
