Found some other information regarding swapping the actuator from the old DA3 to the new DB5: https://pu-parts.com/sub-microswitch-5647-12693
It seems and IIRC the actuator of the DA3 does not fit very well on the DB5 due to slightly different geometry of the "nose" where the actuator "clips" on
Wondering that this topic/discussion does not pop up more often tough
