Sparkfun Illuminated Switch Schematic

I got these really nice illuminated switches from Sparkfun to control the Rubens’ Tube I built with a friend. Wiring them up was strangely non-obvious so I figured I’d post a schematic here.

    Wasn’t half of the problem that the switches are poorly labeled when we got them? Do you remember how they were labeled? That might help as well for reusing them in the future.

    Michael, my diagram is a pretty good representation of the actual switch. So a person should be able to hold up the switch, compare it to my image and go from there.

  3. Michael says:

    I just looked this up yesterday. It’s a real pain to reverse engineer wiring of things that are voltage sensitive without this schematic. The built in switch led drops the voltage enough to really effect things. It’s a little frustrating based on how nice these switches are to use.

    Heh, years later and they haven’t posted a schematic. I posted a “review” with the schematic on the Sparkfun site. Time flies, eh?

    Too be fair, A LOT happened in the interim. My brain always wants to run positive on the device line for some reason.
