Correct whale pump socket replacement

[cencerrita]

I need to replace my whale pump smart pressurized water socket with microswitch in it . Confused when looking at spares as mine is as the photo and has a yellow box attached which is the pressure unit (IC controller)? Unsure which part needs replacing although the blue inside back does not seem to stay flush with housing but pops out a bit. Can i just use the existing yellow controller? The spare sockets I find do not seem to have 3 connection pins on the back except ones fitted with a manual pressure switch adjuster on them which i do not need.
Thanks
Alan

The "smart" ones are prone to failure. You may be better off replacing it with a manual one.
