5-pin SPDT (single pole, double throw) automotive relay.

Relays are essentially two parts in one package. The first part is an inductive coil (pins 85 and 86). This coil is the “trigger” function of the relay. By applying both a positive (+) and ground (-) to the contacts, current passes through the coil. When current passes through the coil, a magnetic field is generated and moves the switch (the arrow in the diagram). This is where the second part of the relay comes into play.

The second part of the relay is the “switch.” The switch has three interface contacts—common, normally closed, and normally open. “Normally” refers to the state of the relay not being energized.

While relays can be used for virtually any task, there are some very useful, simple applications for adding LED lighting to a vehicle. Please note that this wiring only pertains to the relay—not the wires in the vehicle. Before interfacing with a wire in a vehicle, always ensure you test the wire with a digital multimeter first to confirm circuit function.

Positive Switching

Positive switching is used for applications where the “trigger” for your switch or circuit is positive. This could be an ignition, brake, or reverse light wire for example.  This could be used for applications such as off-road light bars, work lights, additional brake lights, and other exterior lighting.

Negative Switching

Negative switching is used for applications where the “trigger” for your switch or circuit is negative. Negative triggers are often found in door, hatch, and trunk triggers as well as many interior switches. This could be used for applications such as footwell lighting, truck bed lighting, under-hood lighting, and other interior lighting.

Switch Activated With Ignition Override

This is useful for applications where you want to turn your light on or off with a switch but only want the light to remain on when the car is running or key is in the “ignition” position. The main advantage to this is—even if the switch is left on—the light (or output circuit) will shut off when the key is turned off so that the battery will not be run down.

If you are lucky enough to have a large family room or “great room”, you may encounter some exciting challenges when choosing home decor and lighting that complements and balances your space. A great room is a large room typically found in modern homes that combines the features of a living room with those of a dining room or family room.

Large, open spaces are very common to find in floorplans these days. The dining room incorporates the kitchen, which is part of the living room and leads into the den, etc.  This trend sees walls to separate activity spaces removed. You’ll find that the kitchen is no longer segregated from the rest of the home but may easily become a main focal point. As you’ll see, the key to lighting these types of spaces is variety. You’ll want to utilize ambient, task, wall, and spot lighting to eliminate a “cave-like” atmosphere and maintain a feeling of spaciousness and height.

Read on for tips on how to set up the perfect lighting scheme for functionality, elegance and entertaining.

Update Your Kitchen Island As An Activity Space

The strike doesn’t even have to be a direct hit on your home but can occur within half a mile.  As a matter of fact, the majority of surges that most people take are from problems at someone else’s home or somewhere further down on the power company lines.  A surge doesn’t have to be lightning; it can come from an automobile accident that hits a power pole or even from a routine maintenance on the main power lines when they turn the power back on.  This off and on of the power with the main electrical lines can send surges into your home or business that I have seen destroy lots of electronic equipment and appliances.

Almost every home has multiple computers, and expensive home entertainment systems.  Even our appliances are high-tech with monitors built into the doors of refrigerators and laundry appliances with electronic controls.  These items are especially vulnerable to spikes in your home’s electrical current that may cause melted circuit boards and overheated wires.  Repairs to these expensive gadgets are much more costly than replacing a blown out light bulb or electrical outlet.
