[GreenKeys] Keyboard always pulled high model 19

[Windows XD]

Dear Greenkeys people,

When I use the keyboard (model 19 but this part should be the same as a 15)
it always shows high. When I remove the keyboard and turn it by hand it
works like it should, and testing the contacts (after bypassing the switch
that shorts them when theres no keyboard) inside there is no short between
the contact and the cable. Only when I put the keyboard in the unit does it
always show as shorted.

Any help is appreciated!
