2 I neogeo:

as described above indicates the point of the wall at which the switch is mounted. The base plate 1 is secured in the same manner as in the previous embodiment. l

The base plate maybe of any desired form, and thus for example may be constructed in the form of a strip clamped between the switch and the wall. Or alternatively it is also possible to employ a number o strips proceeding in different directions and if necessary connected with each other.

Buttons, fuses, electric door openers and similar arrangements may be illuminated in the lsame manner. By the use of glow lamps it is possible to employ the device as desired for all voltages, so that in accordance .with

the invention an independent unit is produced capablel of being employed with existing switches or the like in the most simple manner without anypalteration whatever.

The holes shown in the plates, strips, etc. in the drawing enable the ground plate or the like to be secured by the same screws employed for holding the switc As stated above, I do not limit myself to the particular forms of embodiment shown, and various modifications may be made without departin from the spirit of the invention as descri 4d above and set forth in the ap ended claim.

at I claim as new and .desire to secure by Letters Patent is:

In an indicator, an electric wall switch a amp adapted to burn when the said switch is in the oi position, a base plate adapted to be disposed between the rear part of the said switch and the wall to which the said switch is secured, and an edge abutment on the said base lplate adapted to receive the said lamp.

In testimony whereof I have affixed my signature.

ALEXANDER LULKI.
