INSTALLATION SWITCHGEAR HAVING A LEAD-SEALABLE ACTUATION LEVER

The invention relates to an installation switchgear having an insulating material housing and a switch handle that can be actuated by an operator on a front side of the housing and switched between a switched-on setting and switched-off setting. It is characterized by a frame-shaped slider having a holding protrusion, the slider being displaceably mounted on the front side between a locked and a release position, wherein in the locked position the holding protrusion of the slider blocks the switch handle from being switched, and wherein in the release position the holding protrusion of the slider releases the switch handle for switching, and wherein the slider can be prevented from sliding out of the locking position by lead-sealable means that can be supported on one side by slider bars extending transversely to the sliding direction of the slider and on the other side by structural elements of the front side of the housing corresponding to the bars.
