World's most basic button circuit question.

[system]

Thank you for your reply Lefty. I thought that might be the problem so I rotated the button 90 degrees. When I do that the LED never lights.

By the way, when you say "adjacent" do you mean the first or second layout below? (I don't have a multimeter yet)

1:

--| |-- (a)
--| |-- (b)

2:
(a)---- (b)
--| |--
--| |--

Thanks!
