Hello, I would like to electronically control my ceiling lights and lamps in my house, and I am trying to figure out which relays would work for me.
Based on wikipedia, I want a latching relay, so that the control signal only has to be applied for a short time, and then the lamp should stay in that state until I send another signal.
I am not sure what the relay resistance should be (ideally zero, but I don't know what would be considered tolerable). I don't know how much current will run through. I live in America so I have 120VAC wall sockets.
My control signal will be probably in the 5V range, and preferably battery operated.
So what kind of relays can I get? What should I estimate my current at? What is the maximum resistance I should tolerate? And if you have any other advice I would appreciate it.
thanks

I would like to use latched relays to control the lighting in my house. I don't want any control wires coming out of my light switches (I want to be able to control individual lights at the switch, not rooms at the circiut breaker) so I want it to be radio activated. I want to use latched relays so that I don't have to continuesly transmit an "on" signal (I realize I could use a solid state flipflop) and so that the switch wont take any power except while switching.
I would like the switch and its radio receiver circuit to be controled by a 9V battery, though I am considering building a AC to DC converter into the circuit to take the 120VAC to something like 5VDC.
Does that controll of the relay need a specific signal or can I just hit it with a 5V pulse?
