Hi, Thanks for answering a newb question... I have this pushbutton http://happcontrols.com/pushbuttons/5700044x.htm Which side is the ground for the led? I know the configurations for the button itself. Thanks again, Blue |

The shorter leg of the LED is the cathode: http://www.kpsec.freeuk.com/components/led.htm |

Is that the right link? That's a lamp, not an LED. |
| blueboy:
Hmm..dunno why it linked there. It's part 57-0004-41 Looks like both sides are the same though? Any help THanks, Blue |

Do you mean this? http://happcontrols.com/pushbuttons/91115700.htm If it's a drop in replacement and you get the correct voltage, then you shouldn't have any problems just trying it out in both directions (only the correct way will light up). |
