Relay kit – What’s a relay? This one works. RELAY KIT2 wireless remotes and a relay.WHAT’S A RELAYA relay is a technogeek way of saying a switch, that’s controlled by another switch. You use them when you want to turn something on or off remotely. One example is the ignition switch in your car. It has small wires that go to the starter, which starts turning your engine over. The starter itself has large wires running to your battery because it uses a lot of juice. It would be expensive and impractical to run those large wires to your ignition switch, to the starter, and back to the battery. So, we use a couple relays, one at the ignition switch, and one at the starter.A wireless relay is even better than the above description, because it allows you to eliminate some wires altogether. Although you still have to wire the receiver in – you can do that as close as possible to the device you want to control – then you can use the wireless remote to activate the relay. I did this for my wife’s foglights after I installed them.We’ve all seen movies where they used cell phones, or other wireless triggers to set off their little devices. Those were methods to activate relays and turn their ‘devices’ on.This particular relay works at a great range (I can turn the wife’s fog lights on from inside the house.) It is also versatile enough that it can be used to turn any 12V electrical system function on or off remotely – car igntion, lights, stereo, anything.The directions for this product are sparse – but they don’t need to be too specific. The actual application depends upon YOUR imagination.Did you know your Malibu outdoor landscape lights are likely working on a 12V system? Mine are – I’m thinking about getting another of these units so I can turn them off and on should guests arrive when the lights aren’t programmed to be on.(I would also recommend you replace those halogen bulbs with the luxeon LED’s – 1 Watt vs 50Watt halogen will save you the cost of the bulbs in the first year of their 20 year estimated life span)Did you know that most of those wireless ‘spy’ cameras work on 12V systems? You’ve seen a teddy bear camera on TV to watch the sitter remotely – and make sure your kids are safe. The batteries in those can be hard to change. I bet they would last a lot longer if you could turn the camera on and off just when needed, instead of leaving it on all the time.Those halogen under counter lights? 12V (replace em with LEDs though)Your hot tub motor? (NOT 12V) – but what if you used a 12V relay to turn on a 110 household relay>? then you could activate a wall switch with your remote. Dreaming about the ultimate bachelor pad yet? Perhaps you are just thinking about how to impress your wife?The bottom line: With enough relays, you can turn ANYTHING on!(hope i just figured out how to turn on your smile!)
