Just to double check - can these be used for mains voltage safely?

Not in the open.
They are fine for internal wiring in an enclosure.

It's as much about current as voltage - you need the right crimp colour for the current & wire cross-sectional area. What do you want to use them for?

Just for info:

• RED CRIMP
  Area, wire size: 0.25 - 1.65mm²
  Current rating: 19A
  Material, contact: Electro-tinned Copper
  Material, insulator: Coloured Vinyl
  Temp, op: -20 - 85°C
  Voltage rating, AC: 415V
  
  
• BLUE CRIMP
  Area, wire size: 1.04 - 2.63mm²
  Current rating: 27A
  Material, contact: Electro-tinned Copper
  Material, insulator: Coloured Vinyl
  Temp: -20 - 85°C
  Voltage rating, AC: 415V
  
  
• YELLOW CRIMP
  Area, wire size: 2.63 - 6.64mm²
  Current rating: 48A
  Material, contact: Electro-tinned Copper
  Material, insulator: Coloured Vinyl
  Temp: -20 - 85°C
  Voltage rating, AC: 415V

For a new mains switch I'm adding to my WEM custom 15.

For a new mains switch I'm adding to my  WEM custom 15.

The red or blue crimps will be absolutely fine.
