Hey Guys and Gals,
I'm looking to replace my Button Board on my 4010. I'm assuming the board would be the same as the 406. I've searched the internet and it might as well be looking for nuclear codes. Lol
I've attached a photo. Can anyone point me in the right direction. I've tried suppliers of the Junsi charger and no one has been able to help. And when I say no help I mean no emails back with a YES or NO.

Thanks All!
John

If it is because a bad button, why not replace the button switch? It is called a tactile switch.

I just recently opened up my 308 duo to paint and the button board looks almost exactly the same as the 4010 board. I dont have the charger with me so i couldnt open it up again to confirm now. Any reason you want to replace the board? If its as Roelof said that some of the botton isnt working, you can simply buy replacement buttons to replace the faulty ones. One of my button isnt working that well as well and I need to press it pretty hard a few times before it registers.

I've got the same problem on an iCharger DUO 4010 - thank you to Google for finding this page.

Does anyone know exactly which tactile switch to buy?

I do not know...
A tactile switch comes in several dimensions, shapes and length of the button. When buying them from a good online electronics shop they always mention the dimensions or the factory product number with which you can find a datasheet with all the specs. And what you need is on the board....

But have you the capability of do you have a friend/colleague who can solder?

Looking at the picture ot top it seems they are so called through hole, high chance they are these:
