Power button details?

#1

I recently purchased Anker MP141 portable speaker from UK Amazon for outdoors and it is worth all money.
Although I moved back to India a month ago and Now the power button has gave in.
There are no service centers around and to ship it to nearest country for the same, costs more than the speaker value. Me being expert in Embedded designs can replace the switch myself only if I can get the details of it. I failed to identify it, so did my friends. I obviously don’t want to go for mediocre replacement.

Anyone to focus light on this is well appreciated in advance. This awesome speaker is just sitting idle without the proper switch replacement.

have you taken it apart and taken pictures of the internals?

I’m having the same problem I think. It just randomly refused to switch on or charge.
The switch has 3 terminals. In the two states the terminals read the following voltage vs ground:
OFF
1 - Vbat
2 - Vbat
3 - 0.18V

ON
1 - Vbat
2 - Vbat
3 - 0.68V

No change in terminals 1 and 2. Normally a 3 position switch will be a changeover (switching the centre pin between the two side pins). Anyone with a working speaker wanna check the switch voltages vs ground for us :hugs:) these devices and their planned obscolescence really annoy me.

I had an anker Bluetooth headphone set which did exactly the same thing. Working perfectly one day. Put it down. Pick it up the next day and it refuses to switch on or charge. I’m suspicious they build this into the firmware. Because it was exactly 1 month after the warranty expired -_-
