资源简介：
Described herein is a control assembly (1) for selectively controlling actuation of an electric motor arranged to power a hand-held power tool (3) based on combined performance of two dissimilar operator actions and a hand-held power tool (3) comprising such a control assembly (1). A switch member (6) may be closed responsive to an enabling action comprising a first of the two dissimilar operator actions. A throttle control member (7) is configured to become operable responsive to actuation of the throttle control member (7) past a first movement threshold (REF_LATCH)， i.e. a second dissimilar operator action， while the switch member (6) is in the actuated state. The throttle control member (7) remains repeatedly operable above a second movement threshold (REF_RELEASE)， even if the switch member (6) is opened. Actuation of the throttle control member (7) to below the second movement threshold (REF_RELEASE) will render the throttle control member (7) non-operable until renewed combined performance of the first and second dissimilar operator actions.
