Hello all,I'm working on a small electronic circuit myself here ---->>>
**broken link removed**

I just have three question if anyone can help
1:I have 3 boxheader components here supplied by "spc multicomp",it says on the board that pin 10 and pin 1 of K1,K2,K3 should be opposite each other but i can't find a datasheet for the component I have so I don't know which pin is which,any ideas??

2:B1 and B2 on the board.I think the "+" pin of B1 and B2 is the goes on the bottom left on the board.Is this right?

3:T1BD139:Looking directly down on the board I think it placed pin 1 first,then pin 2 then pin 3,is this right?

Sorry i'm never very good at this so any help is appreciated
