[modeleng] SIP Compressor Problem

I have been refurbishing a SIP compressor.
It is has a 50 litre tank and is a belt driven type. Amongst the parts
I have replaced is the pressure switch (brand new from SIP). This has
two pressure connections. Both direct to the tank.
I am assuming that the two form the "high" and "low" pressure switches.
Switching off at >120psi and turning back on <80psi (approximately).
The problem I have is that from the moment that the tank reaches maximum
pressure (and the compressor turns off) there is tremendous leakage of
air from the pressure switch until <80psi is reached and the compressor
turns on again.
Both the "off" and "on" switches operate the same bank of contacts.
The question I have is very simple and the answer may be obvious (but
the obvious is not always the right answer!)
The question is - Is this a faulty switch, or have I missed a component
in the pressure system? (Although I can't think what).
Cheers
Peter
