Power Switch setup

[RaginCajun]

So I want to set up a bank of gun turrets, using a Power Switch to regulate the flow of power to/from the turrets.  I am guessing that I need to set up a single run of lines from the main grid>to the power switch>to the gun turrets.  But I am having issues and it doesn't seem to work.  I can't get the turrets to come on with the switch on or off. 

Basically here is my setup:
1: Grid one throughout my base
2. Grid two that runs in two directions to reach the guns (g)
g: gun turret bank
S: Power Switch


           2gggg2
           2      2
1         S2222
1        1
111111

Any suggestions?

Soooo  what i do is....I go inside a room or whatever is close to the "edge" of my base I run power lines to the corner, but I do not run one on the actual corner, then i do a power switch in that area and continue the line on the other wall  Hope this picture makes sense

s = switch
w = power line inside a wall
x = wall
- = power line no wall
t = turrets
              x
              x                t
              x
