knowing switch phones

 

The existence of the switch in the phone is absolute. And usually in a mobile phone, there can be a switch. That was just to turn on or turn off the phone, now more and more functions. Call it the phone to wake us from the position of "sleeping" or otherwise make the phone "sleep".

Have you also count the number of times we turn on and off screen mobile phone. If we often do it over and over again, it could lead to switch on / off function becomes damaged or not returned. Without this switch would be difficult to turn on the phone.

If damaged, how do I make sure? The easiest is to feel it. Have you ever felt when we hit the switch, there is something that happens on the switch. There is a kind of vibration or if our ear, no sound when the switch is pressed. Well this is one of the important indicators to determine whether or not the switch.

But the "voice" in the top 75 percent should only be trusted alone. Measurement needs to be done.

1. Use MTD (digital multitester) is set to Buzzer.
2. Measure the foot switch on / off.
3. There should be no sound and should be number 1.
4. Then press the switch must be sound and pointed to the number 0.
