I'm a rookie at this and still having some trouble with my first build... but that's another issue.
Anyway, i'm just trying to understand all this cause i don't like to create something without really understanding it.
In my head a 3PDT switch has each column independent from each other, that is, Lugs 1,2,3 independent from lugs 4,5,6 and lugs 7,8,9. I concluded this from the fact that are needed jumpers between different columns of lugs. If this is true does the signal flow free between each column (that is, between lugs 1,2 and 3, between lugs 4,5,6 and between lugs 7,8,9) ???
Oh, and only after writting the things above i understood this.
On a DPDT or 3PDT stomp switch the columns are isolated from each other. For a dual throw switch there are two columns of lugs (3 for a 3PDT). The center lug is called the Pole. The lug above and the lug below the Pole are the Throws.
