The power supply i'm using is the Meanwell SP-320 24V.
I decided to use a power inlet module with 2-pole swich and integrated fuse holder for maximum safety. The module i am using is the Bulgin BZH01/Z0000/11 fused Power Inlet Module with illuminated 2-pole switch. (Farnell: 9997237).
The images showing the result. For 230V supply voltage a slow 2.5A 5x20mm fuse is recommended.
The protective cover is available at Thingiverse.
