Where can I buy electronic latched relays with dual post? (One post to turn the relay on and the other to turn it off.)
I need to turn on and off 6 lamps (normal 100 watt lamps in my home – 120 volts with about 0.8 amps each). The triggering mechanism will be the Arduino Duemilanove ($45 from Arduino). Wires will extend from the digital pins to the post. For examples:
Lamp #1 digital pin 1 for ON digital pin 2 for OFF
Lamp #2 digital pin 3 for ON digital pin 4 for OFF
Lamp #3 digital pin 5 for ON digital pin 6 for OFF
Etc for all 6 lamps.
The power from the digital pins will be about 4 volts and 34 mAmps.
