Hi,

I bought this nice push button on/off switch on ebay and can control an LED with 12V+ fine with their suggested "ON light ON, OFF light OFF" diagram:

http://www.ebay.com/itm/New-16mm-12V...-/231195939188

However, i also have an LED that turned on with GND signal instead. The LED similar to the DOME light:

from battery ---> DCC --- My_GND_LED ------> GND_wire

If i connect that GND_wire to GND on card, the my_GND_LED will be on alright.

Any electrician could help me out to connect this button to my_GND_LED to "ON light ON, OFF light OFF" ?

Thank you in advance.
