triggered momentary switch

I need to design and build or find a board available for purchase that will close a circuit momentarily using a 5VDC trigger from a small r/c receiver. I just need to close the circuit (to gnd) momentarily, I don't need to apply power. I can find plenty that will apply voltage, but the board I'm trying to trigger has that wired to it.

Am I better off SCR or IC to start?
