Recomend me a decent pressure switch please

[Mantasport]

I have an old Ingersoll rand type 30 model 242 compressor that has been working well for years.

A while back the pressure switch stopped working one day, at least i found out the pressure blow off valve works fine!
Anyway i replaced it with an ebay switch and that isn't man enough for the job. After working for a few days it now needs a tap on the side of the switch to get it to kick in, does switch off still though.

Its really no use at all so am looking for a decent switch and hoping someone here might be able to point me in the right direction.

either buy a decent danfoss one or buy another cheap one and use the pressure switch to energise a seperate contactor to switch the motor if it hasnt allready got one

danfoss or amot

Amot used to be good enough for the lloyds shipping resister, so good enough for most jobs!
