I am a bit concerned about the comment left by tonyvr below about intermittent contact - but otherwise I like the button a lot.<p>For wiring ... if you look closely there are markings ... + goes to the positive side of the LED - goes to the negative side of the LED. There is already a current limiting resistor or something in there ... you don't need an external resistor. The LED draws 8.2 mA at 5V (measured) ... I have the blue button.</p><p>The other three contacts are labeled C1, NO1 (normally open), NC1 (normally closed). So when the button is <em>not</em> pushed, C1 is connected to NC1. When the button <em>is</em> pushed, C1 is connected to NO1.</p></p>

<li><p>The part you press is smaller than all but my pinky finger, so pushing it in far enough to latch is difficult.</p></li>
<li><p>The circuit is completed BEFORE it passes the latching point, so if it fails to latch (most of the time, for me), then it acts like a momentary switch.</p></li>
</ol><p>I was going to use this to turn on power to a device, but it is completely unacceptable for this purpose, sending brief pulses of power to my device when it fails to latch.</p></p>

Apparently they are resistant to "strong water jets" so you can even have a Super Soaker fight around it (but it may not be a good choice for scale-model or full-size submarines)</p>

(when pushed on, it sits indented from when it is off.) (when it is off it is flush with the mounting surface.) hope this helps.</p>
