@jm
many thanks for your patience with my problem.
The following text are my messages in the ide.
I shorted the two contacs ab and then cd. No changes with the leds. Then I took my voltmeter. A=3,3V B=open. Then I pressed the button and B=3,3V. The same with cd. I think, the button must be ok. After that I controlled the voltage of the Pin (I think it's PC13) on the µP with is connected with the button =0V. If I pressed the button voltage=3,3V .
I made another test. I load a programm into to RAM and pressed the resetbutton. Nomally the code was lost, in this case not. I think, the button has no function.
