Hi   , I would need a  schematic,  or a explanation,  for using :  

all in 100mAh, 4 volt
a coil .150 mm diameter, 40meter of wire, ,
a sip, dip switch,
a rf receiver,  
in multiple quantity.

RF receiver gets the information
send it to 100 sip, dip  switch
voltage go to the coil for the switch that went on.
 
voltage ----------- switch
        \                /  
          rf receiver  

I tought it is a way of doing what I want but I work on it now.

What the heck is that? Either it's a Single Inline Pin (SIP) or a Dual Inline Pin (DIP) switch. It can't be both.
DIP switches are usually manual. How are you planning on getting it changed by the arduino?

Also this does not seem to be anything to do with LEDs and multiplexing, the forum's title.

Is going to take a hell of a lot more current than 100mA

0.15mm diameter copper wire has a resistance of about 1 Ohm/metre (0.98/m for the stuff I looked at, at www.roadrunnerelectronics.com). At 4V, the current will be almost exactly 100mA.

Been using that road runner stuff most of my life, it's also called the vero wiring system
Yes sorry it is thinner wire than I first thought. However from this page:-
http://www.cirris.com/testing/resistance/wire.html
130ft (40 meters) of 38 AWG gives 85R

Mind you I still don't know what the OP is talking about do you?

I'm not conversant with AWG, as we use metric sizes here. Before metrication we used the wire's diameter. Now mains cable is measured by the conductor's cross-sectional area. e.g. 2.5mm2 for up to 15A (250V). I'm not certain about how thinner wires are measured, as it seems like the manufacturer decides whether to go by area or diameter.

Nope. I'm still puzzling over what a SIP DIP switch is.
