The most commonly replaced parts of the power tools are the Switches and the Carbon Brushes. The symptoms of the breakdown of both the carbon brush and switches are similar, and the failure reason is also alike. Thus, it isn’t easy to diagnose between the carbon brushes and the switches. There are various cases where you can find the reason of the failures in both the part but in few cases it is a problem in the operation of the intermittent tool that causes the failure in the carbon brushes and the switch.
The switch usually lies behind the main trigger and controls the power flow from the tool’s wall. The less performance is done by the switch in case it got worn out. It works efficiently in the first attempt, but occasionally it needs to be clicked on a few times to get started. It will often make you click the trigger frequently, but it will work correctly once it gets started. So, you can replace the switch with the new one rather than throwing the power tool.
The carbon brushes do the power transfer to the motors of the power tool. But it is a little divergent to that of the switch. The cut out of the power tool starts while functioning when the carbon brushes become marginal. During this, the tool gets started by the trigger but not that well. This sort of issue depicts the problem in the carbon brushes. You have to diagnose the problem before replacing the carbon brush. Some carbon brushes get compatible with the power tools by using the Einhell Carbon Brushes to control the power flow.
Thus it is essential to notice and keep notes of issues in the switch and carbon brushes. It is very significant to inspect inside the tool, appliances, and machine before replacing it.
