### Note
|
|
|
|
* It improves the feel of the buttons if none of the wire leads protrude through the top of the button board. (Otherwise, the button pad doesn't sit as nicely on top of it.) One way to assure this is to solder all connections only to the underside of the board, as is shown below. However, it is alternatively possible to poke the leads into the inside of the board as long as they don't protrude through the top.
