I know you all know my six dof robotic arm 
and I am a power problem and ı need yor advices I have SSC-32 card and it has one switch
both conrol microcontroler and servos I think it creates power problems because my servos do not work well , it means when I switch on All power feeds microcontroller and servos I use firstly 9V then 6V batteries both nothing changes in fact I hope ane switch is enough please help me about this thank you.
This switch that you mentioned…
Is it the DPDT switch + RC connector that you can purchase at LM, or is this a switch that you bought seperately?
If you bought the switch seperately, it’s internal contacts might not be large enough to flow the 3A or so that your servos will need.
Try connecting them without the switch.
If it works fine, then buy a switch that’s rated well over the current that you’ll need.
If problems persist, post some pictures (you can upload them at www.putfile.com or many other similar sites) of your setup, and we’ll take a look.
You are one number one my firend that is link putfile.com/serdarmg/images can you look at it please
thank you very much
The switch and connections look good. However, the red & black power supply wires (from the switch to the SSC-32 board) are pretty skimpy (too thin). Also as Nick said, you need more power. Try 4 “D” batteries (6Volts) or a 6V lantern battery and replace the wires from your switch & batteris to the SSC board with higher guage (thicker) ones.

I’m thinking it’s the wire, as well.
It looks like you’re using communication wire (about 24 AWG).
You’ll want to use wire that’s at least 18AWG.
I’d recommend going up to 14-12AWG, though, since it wouldn’t hurt.
That switch is, indeed, fine.
Toggle switches like that are usually rated for high currents at AC levels, so you’re definitely in the clear.
Thank you firends my robot start to moving with your helps but It sometimes move different motions I think it is about a power problem I also use battery for moving my robot and I think ıt’s power does not enough to move All joints of my robotic arm proberly so I tihnk ı use my adpater putfile.com/pic.php?pic=main/7/2 … .jpg&s=f10 you can see my problem will solve what do yu think? ; my only problrm is this adptor for 120Ac but in my country Electricih is 220Ac so I need a converter thank you for your helps 
If that’s a 6-8VDC 2-3A transformer, then it should do the trick.
You’ll probably want to put in a fuse, as well, just in case your servos overdraw the supply.
If you can’t find an adaptor for the head, and you decide to just cut and strip the wires, the wire with the white stripe is usually positive.
Sorry I forgot write my adaptor properties it is 5V DC 2.5 A is it enough
you think? thank you
yea, the servos can run at 4.8 volts andi dont think they’d draw that much current
The 5vdc wall pack is enough current to make the arm work. However you need to supply the VL (logic) input with a separate supply to prevent the SSC-32 from resetting. Remember to remove the VL = VS jumper when doing this. The arm works best with 6vdc for the servos. The extra volt makes the servos stronger.
First of All thank you for your intrests and advices they helped me very much ;I am another question in my country we use 220 V in our city electricty system but my adapter which produces 5V DC 2.5 A from 120 AC I order a converter but it is from 220 to 110 V AC do you think is there a differencs between 120 V and 110V for servos and micrococontoller if there is I will look for a 220 to 120 V adaptor
thank you very much
going to 110V should be fine.
Thank you for all your attention and advices My software Rioa and robotic arm are working perfectly I am a haapy man :)
