Hi Guys!
Hope you all had a good start into 2017!
As title says, maybe a dumb question .. but I've no good skills in reading electrical schematics! :(
In my 747-400 OVHD panels are lot of Korry 434 1/2 x 1-Inch Type I indicators. Here is the electrical schematic:

What does the wave (red arrow) exactly means?
Thanks for your help!
Cheers
Hans
PS:
If you are interested in: more tech info about the indicator here:

That symbol is usually a fuse.
Thanks, Kyle!
Interesting: one line with, another without fusing goes to the same lamps. Idea why?
Cheers

hi bud..did you get these panels from Jeff ? before you go tearing into them there is a part number.. which korry is it.because these might be from old Everett sim
Hi Bernard,
I got them all from UAM!They are mostly from United Airlines 747.
I've mainly two types as far as I recognized:
434-093-001
81590 9923
Type I
and
434-674-1031-2318
81590 0133
Cheers

then as stated with triangle i assume x2 because of built in redundancy ..do you have schematic for each type ?
This is imprinted on the indicator (same as schematic above):
