Hello and welcome to this annual us on in which are going to cover switch testing us which is basically

2
00:00:07,650 --> 00:00:15,530
an element that allows current to flow to continue or to connect a circuit elements together.

3
00:00:15,570 --> 00:00:20,580
Now it comes in different shapes as you can see in this image.

4
00:00:20,760 --> 00:00:32,340
And if you want to start using a multimeter using that continue to test on switch means that the multimeter

5
00:00:32,340 --> 00:00:39,470
will beep when you are connecting your blobs of the multimeter to the tool that two terminals of the

6
00:00:39,480 --> 00:00:40,700
switch.

7
00:00:40,770 --> 00:00:48,510
If you are connecting them and you switch off your switch it will not be this way.

8
00:00:48,600 --> 00:00:51,890
You know that your switch is working just fine.

9
00:00:51,960 --> 00:00:59,760
Now if it does beep in both way and on state and off state it means that there is a problem with that

10
00:00:59,760 --> 00:01:00,630
switch.

11
00:01:00,630 --> 00:01:07,680
And if it does not be at all even if it was on it means that it's not working properly.

12
00:01:07,860 --> 00:01:12,660
So it's very easy very straightforward very similar to the fuse testing.

13
00:01:12,810 --> 00:01:14,280
So that's it.

14
00:01:14,280 --> 00:01:15,510
Thanks for watching this lesson.

00:01:15,510 --> 00:01:18,180
