An electrical network-powered hand-held power tool () includes a connection device for connecting the network cable with a power tool cabling and arranged on through-opening () through which a network cable () projects, with the connection device () having electrical connection elements () with which the network cable () is connectable, and securing elements () for securing the network cable (), and with the electrical connection elements () and the securing elements () being at least partially displaceable out of an interior () of the housing () through a mounting opening () of the housing () upon lifting of the mounting cover () off the mounting opening ().

Electrical network-powered hand-held power tool

A hand-held electrical combination hammer drill capable of being used both as a drilling hammer and as a chisel hammer, and including an actuation member () for actuating an electrical on-off switch of the hammer drill and located on the tool handle switching elements () for switching between drilling and chiseling operations, stop elements () actuated by the switching means () for retaining the actuation member () in a on-position of the on-off switch upon selection of the chiseling operation, and a stop switch () having, upon selection of the chiseling operation, a first position in which the stop switch provides for securing the actuation member () in its on-position with the stop elements (), and a second position in which the stop elements occupies a non-operative position in which the actuation member, upon being released, automatically moves into its off-position under an action of a biasing force.
