Hi I’m using spacers for mounting main pcb on wood baseboard of model rail but have one relay pcb and another pcb no mounting holes how can I fix please and still being removeable as looked at sticky Pads but my experience not very good any help would be much appreciated
Try searching for "snap track". It comes in DIN rail mount or flat surface. You probably want flat mount.
If you have an odd size pcb you could cut the snap track and modify it to your required dimensions.
