I think I screwed up. I am building a test fixture and need to have some user controls on the board. I added a few push buttons as controls and LEDs for feedback. While I was browsing Mouser looking for good switches, I found an inexpensive 8 way joystick switch from ALPS. The data sheet seemed reasonable, so I added the part to my order. Now that I am laying out the board, I realize that the ALPS data sheet for the RKJXS1004001 does not have enough info to be able to connect the part in the circuit. It has a diagram showing the terminals with labels such as 1-4, C, E and P. But it does not indicate which terminal is closed for which movement or which terminal is the common, not to mention that there is one too many. Further, this is an SMD part with oddly shaped pads and they don't provide any dimensional data.
Looking at another, similar switch from ALPS, they provide all the info you would need. I have written the company as well as Mouser and have not gotten back anything useful. How does anyone design with this switch if they won't tell you how it works? I thought I might be able to ohm it out, but I just don't have enough hands (or feet) to hold the switch, the probes and push the control around. I don't even think you could do it with two people since the part is pretty small.
Anyone worked with this part before?
