Relay question (adding relay to Oscars LED driver board) - it works!

JoyMonkey:

I've got these cathode lights hooked up behind my cocktail cabinet's control panels, they work great, but I'd like to add a relay so they only light during gameplay. I can use an AdvMame script to set the Scroll Lock LED to only light up when a game is being played.

My question is how do I get the scroll lock LED to control the cathode light? What kind of relay do I need?

Popcorrin:

I would use a SPST relay, but a SPDT or DPDT would work fine also.  It will need to switch off of a 5V supply but it will need to draw a low amount of current, I would find one that is rated at a nominal wattage of 200 milliwatts or so.    As far as the current flowing thru the relay to your cathode lights, a rating of 1 amp should be fine.

JoyMonkey:

Do you think  this relay would do the trick?
Sorry, I'm a little clueless when it comes to this electronical lark.

Popcorrin:

That should be perfect.

JoyMonkey:

Cool. Thanks!
