Here's my version, with just a bit more info since I took my URC apart.
The bi-colour LED is only necessary if you're using a pushbutton switch that doesn't give any indication as to which state it's in (ie. in/out), but if you use a toggle or rocker switch then you don't need it (unless you like more lights!)

I found the connector at Newark Electronics, their part # 97K5346. $3 - so buy a couple - the pins are tiny and the ABS can melt if you don't solder quickly.
