I have to put a new pressure switch into me water pump. I have a square d with 4 terminals.

1. line
2. load
4. load
3. line

would I be right in thinking that the power in goes, brown/Red to line 1 and blue/black to line 3 and 2 and 4 with corresponding colours goes to the motor and the earth of course goes to the frame.

Yes, that would be correct IMO.
