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.

With the explosion of home renovation shows such as House Detective, Holmes On Homes and Income Property, you would be hard pressed to find the person who isn’t aware that any renovation of an older home would require the specialized services of a licensed, qualified electrician. Often conjuring up images of the older, ‘quaint’, 40+ year-old home, the word “renovation” has almost become synonymous with a neglected home in disrepair, complete with bundles of wiring that could pass for extension cords. Obvious stuff that would appear glaringly unsafe to the average person.

What doesn’t come to mind is your typical, one or two-story home built anywhere from the 1980’s to early 2000’s.  But in today’s housing market, doing a kitchen and bath remodel could mean the difference between a sale and seeing no movement at all. Whether it’s to compete with newly built homes in a weak housing market or to increase the value and enjoyment of one’s home, a homeowner would be prudent to consult a licensed electrician when making any updates to their home. There can be unforeseen dangers when combining newer, modern appliances and lighting with existing wiring and a licensed electrician can inspect and update your home’s electrical framework, ensuring its safety and increasing energy efficiency.

In a case of one trend bringing about another, the increasing popularity of in-home offices and theater rooms has  sparked the inclusion of structured wiring, or heavy-duty electrical and data cables designed to manage the latest (and yet-to-be-invented) electrical devices. Take into account that almost 50% of new homes built in 2008 included structured wiring and you can see that this trend could very well become the norm in the near future.

One of the most popular lighting trends of the past decade has been the use of via etsy.com

Antique or edison light bulbs generally come in a few different shapes. One popular shape is the tubular light bulb, and the DIY fixture above is a great use for the tubular light bulb shape. Tubular antique light bulbs really show off their filaments, and the glowing filaments are the star of the show!

2. Also Pretty Tubular!

Candelabra based antique light bulbs are very popular and are great for use in chandeliers, pendants, and other fixtures that use this smaller kind of light bulb. I didn’t want you to think that antique light bulbs only came in medium-based varieties. No, you can create a vintage lighting look with your fixtures that use candelabra based light bulbs, too.

4. Blowing the Dust Off an Old Look

Another popular shape for edison light bulbs is the globe. This envelope shape is more spherical and looks great alone, but when grouped together as in the above photo, you can see the reflection of the glowing filaments in all the globes of glass, and this is a pretty neat effect. Such a warm look.

6. The Industrial Look

Some people like to use antique light bulbs in new fixtures that look old, and some people like to use antique light bulbs in old fixtures that look new. In this case, very old cages have been restored to use in a new light fixture. This represents what edison bulbs are all about, holding onto the beautiful things of the past. In this age of integrated LEDs and the dawning of things like via etsy.com

This homemade light fixture features quartz crystals hanging down amongst the edison bulbs. This is pretty neat. The crystals are the perfect things to arrest the warm glow emanating from the antique light bulbs. What a creative idea.

9. Wall Sconce

Anytime you pay money to a contractor, there are going to be risks. Hiring someone for a job may be a source of anxiousness for you as you try to determine who is going to do the best job in a timely, professional manner without breaking the bank. This is a decision that deserves some time. You will definitely need to do a little homework before you hire anybody to complete a big job that actually puts the safety of your home and ultimately your family in their hands. When you need the right electrician, Los Angeles homeowners can count on the team at The Electric Connection to do a job up to code and up to your high standards.

There are 4 things you should look for when you begin your search for an electrician in Los Angeles.

1-Overall good reviews from people who have used the electrician or company in the past. Checking Angie’s List is one way to get some honest reviews from real people. You will likely find testimonials on the business website as well.

2-Ask around. Businesses have a reputation in the community. Talk with neighbors, co-workers and friends to ask if they have a particular electrician they would recommend. They can give you an honest opinion and the little details you won’t hear anywhere else.

3-Every contractor you hire to perform work in your home should be licensed and bonded. This insures your home is covered should something happen during the course of the work and also protects the Los Angeles electrician. Homeowners can check the status of the license by making a quick phone call.

4-A company that has a good record of showing up as scheduled is also important. Everyone has schedules to keep and one person showing up late can throw it all off. Punctuality and the ability to stick with a completion schedule is very important.

If you are in need of an electrical contractor, give The Electric Connection a call and let them take care of your electrical needs.
