In this case, a loose connection generated head and melted part of the plastic switch casing in the circled area: Fried power switches will have to be replaced, but it's a pretty easy and quick fix that will keep the power tool running down the road.

They are almost always retangular or square with one end connected to the wiring coming from the switch, and the other end making contact with the motor.

Carbon brushes touch part of the motor assembly called the armature. The part of the armature that carbon brushes touch is called the commutator and is located on one end of the armature usuallly the end closest to the power switch assembly. Carbon switches are held into place by brush holders which make sure that the brush makes contact with the armature at the correct angle.

Brushes also have springs to make sure that the brush applies the right abmount of pressure to the amature when making contact. Everyday Wear: A tool's armature assembly spins while the tool is operating including the commutator which means that carbon brushes wear down naturally with regular use. Replacing worn brushes is important to maintain a good electrical current running through the tool.

What to look for: Worn down brushes will make it hard for a tool to start up, but it will be off-and-on. One minute it will work fine, and the next minute it won't work at all. This is because the brush is alternately connecting and not connecting with the armature—completeing and disrupting the circuit. Hint: This can look a lot like a power switch failure at first, but if the switch checks out ok which is the right place to start , then a bad or worn brush is the next part that should be inspected.

Brushes will normally have a contoured wear pattern on its contact end that matches the contour of the commutator where it touches the armature. When wear on the brush passes the wear line marked on it, it is time for a replacement. Heat Damage: An overheating power tool will wear carbon brushes down faster and damage the surviving portion of the brush, making it less conductive.

The tool will work off-and-on , like with worn brushes, so checking the power switch is the first step in figuring out the source of the problem and what needs to be replaced. What to look for: Brushes that have overheated can show a few different signs. The first signs of an overheated brush are dark burn marks on the brush itself and a heavy contoured wear pattern.

Discoloration can also appear on the wiring connected to the brush. The shade of discoloration can range from silver to copper or gold, depending on the power tool. See the example of wire discoloration below: Chipping Damage: Carbon brushes are sometimes chipped by a damaged or worn armature. Chips n a brush means that there will be gaps in conductivity when the armature spins, making it so the tool only works off-and-on when the gaps line up just right.

Again, this problem might look like a power switch issue until the switch checks out ok. What to look for: A chipped brush should be easy to identify just by looking at it. If the brush really is chipped, taking a look at the armature for chips is a good idea while the tool is dismantled.

Installing a new brush into a tool with a chipped or worn armature will probably just cause the new brush to be chipped as well. Checking an armature for chips and wear is explained below under Armature. A burr can cause the same problems as other brush issues by preventing the brush from sliding into its brush holder correctly. Luckily, most carbon brush burrs only need to be filed down a little to be fixed. But a new burr might just form again if the worn armature that caused it isn't replaced.

What to look for: Just look for the burr and file it down. Checking the armature for wear or chips is a good idea while inside the tool. For a "Brush Diagnosis" article--Click here. An armature is the first major half of the motor assembly. An armature is a shaft -like assembly piece that spins as the tool operates. Armatures connect to the tool's brushes at one end of the armature called the commuator , which is the copper, segmented section on the left-hand end of the armature assembly pictured below.

Commutators are important because they are the site of contact between the electrical current in the tool and the tool's motor assembly. The commutator is located at one end of the armature shaft. Most armatures also include fans to remove dust from the tool and to keep it cool.

Most aramtures pretty tough. A tool's brushes are much more likely to wear down before a tool's armature suffers heavy wearing or chipping, but overheating the tool will speed up armature wear a great deal. Wear-Damage and Chipping: Commutators are segmented , with each segment divided by a groove.

If a place between the grooves is chipped or worn down low, then the comutator will not be able to deliver consistent power to the rest of the armature and motor assembly. Chipped or worn armatures commutators can chip brushes in turn, increase a brush's wear, or develop a burr on a carbon brush.
