Oral-B Vitality Power Button Replacement

Introduction

Electric toothbrushes are powered on by a small on/off switch located on the outer case of the toothbrush handle. The on/off switch signals the circuit board to power the motor. If you press the power button and the toothbrush doesn't power on, most likely the power button needs to be replaced.

In my case no need to change the button, just redo the solder and this is it.

the vibration has damaged the solder.

If you try to unsolder the battery it has some protection and it won't work anymore

Before unsoldering the button, you can understand if it is good or not just bypassing it with a wire: with a copper wire you can touch two pins of the button (one on the right side, on on the left side); if the toothbrush starts and stop on each touch of the wire, the problem is the button. I recognize the problem in this way.

True except if the switch is permanently “on”. I think that was my case. Replacing the switch fixed the issue.
