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.

Each and every household has at least one reason to conserve energy. This is a very basic idea, and should be important for everyone in all classes of society. By conserving energy you are being less wasteful, which can have a positive impact both on the environment and on your monthly energy bills. In most areas, electrical utility companies still use fossil fuels to provide our homes with the electricity that we use on a daily basis. This includes materials such as natural gas, coal and oil. The exhaust and other by-products of burning these fuels can be very harmful to the environment. Furthermore, they all have a limited supply that is rapidly declining due to the increased demand placed by humans.

What can you do to conserve energy at home?

One of the best places to start is to use your appliances mindfully. By this, we mean turning them off when they are not in use. For further power savings, you can even unplug them or turn an attached power strip off to avoid losing any “standby” power.

Your large home appliances, such as washing machines, dryers, refrigerators, air conditioners and heaters can account for up to two-thirds of the energy that you use at home. By unplugging them when not in use, or ensuring that they are only being used when necessary, you can make a significant dent in your electric bill. Take important steps such as turning your thermostat up when you leave the house, or improving your insulation. You can have your electrician in Los Angeles install time-saving devices such as programmable thermostats and dimmer switches to make this job even easier for you.

The bottom line is that everyone should be doing their best to conserve as much electricity as possible. While the effects may seem small, they truly add up and can benefit you both personally and everyone around you.

The relationship between weather and energy usage is a never-ending cycle. Spikes and drops in temperature and humidity lead to spikes and drops in energy use (and costs), which in turn correspond with spikes and drops in greenhouse gas emissions, further affecting climate. What does this relationship mean when it comes to your energy usage?

Temperatures above 100 and below 40 stress your heating and cooling system, pushing it to capacity, reducing efficiency, and draining energy supplies, along with your wallet. Quite simply, this amounts to less bang for your buck in terms of comfort. Add to temperature issues, wind, cloud cover, and precipitation and the snowball effect continues, further impacting comfort levels, not to mention your ability to illuminate interior spaces. Compound the issues – and the population affected – and you’ve got grid strain to boot.

That depends on the source of energy. In the US, 83 percent of energy usage comes from fossil fuels, which release gases such as CO2 into the environment during the creation of energy. Unfortunately, these gases trap heat in the atmosphere. Atmospheric greenhouse gases have increased 30 percent since the pre-Industrial Revolution era alone, and the level continues to rise with energy demand. As levels increase, so does the effect on the environment. Thousands of scientists agree the trapped gases are currently affecting the climate, and will increasingly weigh on it as time goes on. This has resulted in an increase in interest in cleaner forms of energy, including nuclear, solar, wind, and geothermal.

If you are looking for a Garland electrician, be sure to find one who cares enough about safety to help determine if your home is up to par. Some older homes often lack basic precautionary features that are inexpensive, yet vital to the safety of the family. One of these features is the GFCI, and any Garland electrician should be able to determine if your home has one.

Recently in Texas, a family experienced a heartbreaking illustration of what can happen without a GFCI. The mother was bathing her two children, ages five and six, when a hairdryer that was plugged into a nearby outlet fell into the tub. Both children were killed by the electrical current passing into the bathwater.

One of the most horrifying things about this story is that this accident was preventable! Installing a Ground Fault Circuit Interrupter, or GFCI, could have saved these children’s lives, at a cost of less than $60. The circuit in their bathroom was not equipped with this simple piece of equipment, simply because their home was an older home.

When the electrical current is imbalanced, it indicates that the current is passing through something that it is not intended to pass through. A GFCI handles that situation by quickly interrupting the flow of current before it can do harm. Water is an especially dangerous conductor of current, so a GFCI should be installed everywhere that an electrical device might be plugged in near water. This means that GFCIs should be on outlets in not only kitchens and bathrooms, but also in garages, outside, near countertops, and near hot tubs and pools. While a layperson might not realize that, an electrician should. That is why, whether you are looking for a Dallas, Garland, or Rowlett electrician, you should make sure to find one with enough experience to spot potential hazards before they cause tragic results.
