Software engineer fearlessly venturing into the deep, terrifying, murky waters of electronics here. And hoping everyone can take pitty on me (and be gentle) as I ask this simple question...

I'm looking to connect this momentary switch to a solderless breadboard but its datasheet seems to be a datasheet for a generic set of devices in the same family of switches that the manufacturer makes.

I'm just looking to understand what its wiring would look like. I have to assume (based on my heavily limited knowledge of electronics) that there are pins for: output signal (when the switch is pressed/closed), ground/GND and (because its illuminated) its internal LED...or would pressing the switch also trigger the internal LED to light up?

I guess my question is: is there information in its datasheet, or on the DigiKey page, that would tell me how to wire it up on a breadboard? Or is the datasheet junk? Or am I supposed to just have working knowledge with switches/electronics to begin with and the wiring of this device would be obvious to most EE folks? Thanks in advance!

  • \$\begingroup\$ Looks like the PN on the site is not corresponding to the actual part. It is listing A22NZ-*, but the family is A22NL. Also I can't find the specific PN in the catalog ordering information. \$\endgroup\$ – Eugene Sh. Oct 3 '17 at 18:47
  • \$\begingroup\$ Yeah thanks @Transistor (+1) - remember I'm a newb so from the device page (linked in the question above) I see a link for Datasheets. Is that not correct? \$\endgroup\$ – smeeb Oct 3 '17 at 18:48
  • \$\begingroup\$ @Smeeb.. the issue with your link is... in 6 months digikey may no longer carry that part so the link will be broken here. Use the direct link to the manufacturer instead. \$\endgroup\$ – Trevor_G Oct 3 '17 at 19:35
  • \$\begingroup\$ Also it often helps if you list the exact part number here when the datasheet is for a family. We have no idea which particular variant especially LED voltage you have chosen. \$\endgroup\$ – Trevor_G Oct 3 '17 at 19:39

With switches look for the switches internal connection diagrams that are usually included.

Here from page 15 of your switch you linked..

enter image description here

Note the illumination is fully under your control.

  • \$\begingroup\$ Thanks @Trevor but what exact URL is that from?! I can't find it anywhere on the DigiKey page linked in my qestion! \$\endgroup\$ – smeeb Oct 3 '17 at 18:50

    \$\begingroup\$ @smeeb DIgikey always links to the actual Datasheets which is nice. Look at the link under documents and media in your linked page. \$\endgroup\$ – Trevor_G Oct 3 '17 at 18:55

    \$\begingroup\$ It's a normally-closed switch. The X in a circle is your lightbulb \$\endgroup\$ – Eugene Sh. Oct 3 '17 at 19:17

    \$\begingroup\$ No, no, no. The diagram is of internal connections. Which are inside the switch. If you want it to close some circuit, when pushed, you connect that circuit on pins 3&4. If you want it to disconnect on push, you connect it to 1&2. If you want it to light up, you connect voltage to X1&X2 \$\endgroup\$ – Eugene Sh. Oct 3 '17 at 19:33
