Claim:
An installation switching device comprising: an insulating housing having a front face; a switching handle disposed on the front face and configured to be operated by an operator and switched between a switched-on position and a switched-off position; a slide fitted to the front face and moveable between a locked position and a released position, the slide being in the form of a frame and having at least one transverse web transverse to a movement direction of the slide and a holding projection configured to block any switching of the switching handle when the slide is in the locked position and to release the switching handle for switching when the slide is in the released position, the holding projection including a flat tongue extending from the at least one transverse web into an interior of an opening of the frame, the flat tongue being configured to engage with a corresponding locking contour in the switching handle when the slide is in the locked position so as to provide a coupling between the slide and the switching handle, the coupling blocking a switching of the switching handle, wherein the front face includes at least one structural element corresponding to the at least one transverse web; and a lead-sealing device configured to prevent movement of the slide from the locked position, wherein the at least one transverse web and the at least one structural element support the lead-sealing device.
