Hi Klem,
as I already mentioned the HCF4027 is pretty touchy and sensitive to noise.
It may be a better idea to make a PCB.
Here is a revised circuit including the debouncer circuit.
Shorting wires instead using a switch will result in multiple triggering of the circuit, although it already contains a minimum debouncing circuit.
The HCF4093 gives clean square wave clock pulses, no matter how often you "retrigger" the input. The output swings high until you release the pushbutton + the the time determined by the RC network.
The board size has increased to a length of 88mm and a width of 21mm with one wire jump, clearly marked.

P.S. The PCB layout is not finalized yet.
