Hi Per!

Another question because I'm having problems with the keyboard.
Two of my Hall-Sensors-Ic are defective. I couldn't repair it, because I couldn't find a replacement for it.
To make it work at all, I swapped the sensors on the two defective buttons. I.e. I swapped them with those of two "unimportant" buttons.
Do you know a source for these keyboard parts?

Hi Axel

No im not aware of where you can get those. I dont have the keyboard handy, it's in place of the monroe right now.

But is it the ic's or the buttons you meen?

Hello Per

The problem is in the key. It's not a mechanical problem.

When you press the button, a magnet is pushed in front of a Hall_iC.

This sits on a small circuit board and is inserted into the key housing from below.

There is a picture of the building block in the attached document.

On page 10 --> Model "three-terminal(E)"
