Switch position indicators for electrical switchgear

The innovation has a switch position indicator for electrical Switchgear to the subject

The known switch position indicators arranged within the device usually consist of a two-armed lever swinging around a fulcrum, on one arm of which the switch lever, a traverse and the like are articulated, and on the other arm an indicating surface movable in front of a viewing opening with the The words "EIN ¹¹ and« AUS ^{11 are} attached to the so-called position.

As you strive for it, the gearshift indicator near the gearshift lever to bring, difficulties often arise and a considerable one Effort with regard to the transfer elements

In order to provide a simple design of a switch indicator for electrical To obtain switching devices ■, this exists according to the invention from one in a wall of the housing of the switching device a viewing opening with a cathetus directed against this opening Prism made of e.g. glass and one in front of the other cathetus de * prism provided with a characteristic surface, movable lengthways, from the drive of the switch or from the contact bridge directly or indirectly operated slide and one behind the part of the slider to be moved away further identification »

It is recommended to put the mark on the surface of the slide and to form strips of different colors behind the part of the slide that is to be moved

The drawing shows an embodiment of the invention in two figures

FIG. 1 shows the illustration of a device designed as a series device and a remote switch operated by a solenoid,

FIG. 2 shows an enlarged section of the switching device, in which the ad is located

As usual, the switch has a housing 1, in the top 2 of which a viewing opening 3 is arranged · In front of this viewing opening 3 there is the prism 4 »in such a way that one cathetus 5 is in front of the viewing opening 3 · In two" arranged on the drive magnet Guides is behind the narrow wall 6 of the holder housing 1, a switch slide 7 for the actuation of the switch springs B out, which is connected to the drive _{armature 9 of the drive magnet β} The end of the slide switch 7 faces the second cathetus Io and has a color coating on its front , z «B * a green stripe 11» On the projecting wall 12 behind the slide switch 7 there is also a colored stripe, ζ · Β «of red color 13» By reflection on the hypotenuse 14 of the prism 4 one can see at the viewing opening 3 recognize the color and thus the switch position of the switch «
