Can someone help me interpret these diagrams?
That datasheet is not entirely clear to me - I'd want to get the switch in hand and measure continuity between terminals before laying out a PC board.
It appears that with the button released terminals 6 and 4 are connected, as are 1 and 3.
With the button pressed, 6 and 5 are connected, and 1 and 2 are connected.
To me, the connector drawing doesn't really indicate that - the two arrows pointing in opposite directions are confusing.
