The batteries were replaced 5 months ago and it worked as new. Now it stops working. When I press the switch, it power on for 1-2 seconds then stop. I believe it is is the switch problem. Any suggestion on where to get the part, a tact switch? or an alternative part to fix

I seem to have fixed my brush by removing it from the outer case and placing it in the oven at 50c for 15 minutes. It has now been working flawlessly for 2 weeks.

Seems as if there was moisture affecting the circuitry.

Same problem for me. Changed battery 10 months ago and now when I press the button it vibrates once then stops. Battery is fully charged but don't think the switch is faulty.
