Please explain. The 15-1994 doesn't send RF. Is this an X-10 controlled switch, so you are implying that an IR-X10 converter such as the IR543 is also used? What was the cost? Do you know if it is identical to other X10-branded switches, or switches by Leviton, PCS, etc? Is it a pushbutton, decora-style pseudo-rocker, or decora-style true rocker?
