Actuation handle for IMH safety switches, etc.

The innovation concerns an operating handle for NH fuse switches.

Such handles are used to switch the NH fuse switch on and off, They are usually on the front or top of the switch cover attached, whereby these devices in the height bzui. in depth around that Dimension of the handle can be increased. Switches attached to the front Operating handles also have the disadvantage that they cannot be built into encapsulated systems because of this handle arrangement the cover cannot be removed when the switch cover is switched on.

There are NH fuse switches known in which the switching square so are designed that their upper end faces have recessed grips. This arrangement eliminates the need for additional operating handles and the Switches can be made relatively low. Safe handling, however, requires a certain depth of the recessed grip and thereby also of the switch cover.

The innovation has set itself the task of a fuse switch to create, dgsean switch cover and operating handle so designed is that the device can be built in flat distributions. That The main feature of the innovation is that the operating handle rotatably mounted on the side walls of the switch cover and in a Trough is retractable.

It ···

In the drawing, an embodiment of the innovation is shown. It shows an NH fuse switch in side view.

The SichGrungsschalter consists essentially of the Schalternhassie 1 and 2. the rotatably mounted thereon selector cover This is designed to DAG its upper end forms a trough 3 which is laterally through the Be tenuuände 4 and limited by the base plate 5 downward. In the bearing points 6 of the Seiteniuände 4, an operating handle 7 is rotatably mounted. It is fully sunk in the recess 3. As an example. Switching off the switch cover 2, the actuating handle is pivoted into the position shown in phantom, in which it is locked by stops 8 on the sides 4.

As can be seen from the drawing, the renewal according to Arrangement despite the lower recessed grip bzui. lower switch cover one Functionally reliable actuation of the NH fuse switch achieved.
