As at 12/08/2021 I understand this part is now obsolete. Search for the parent brand Schulte
It's 24mm wide. The single pole switch is 12mm wide. See the comparison photo above.
This will fit many pressure cleaners with different part numbers, check out Pn. 3819620 for a more affordable alternative. Note: the actuator length, and length of travel and spring pressure can make a difference to if they will work or not.
I agree this is very confusing.
