I'm not sure of the actual sequence of these letters, but I too was looking for these low voltage relays. I was scanning the internet, which in turn, led me to this site. I have a customer that has these in her house, and I have to replace a few. Her's are "Remcon". Other's I've worked with were called "Touch-Plate". Anyway, I'm glad I've finally found a source. If I can be of any help to anyone, please send me an email.
