INTRODUCTION

The Ashcroft

differential pressure switch is a precision built U.L.

and C.S.A. approved control device which features a mechanical

snap action switch. Controllers are available for operation on

various pressure differentials with fixed or variable switching dif-

ferentials. Also, manual reset types are available for operation on

increasing or decreasing pressure. The manual reset types

remain tripped until reset by pressing a button on the top of the

enclosure. The standard electrical switch is SPDT and is avail-

able with various electrical characteristics. Two SPDT switch ele-

ments mounted together are available except on variable dead-

band and manual reset types. Various wetted material construc-

tions for compatibility with a wide range of pressure media may

be obtained.

The Ashcroft snap action temperature switch is furnished in the

standard NEMA 4 and explosion proof NEMA 7 and 9 enclosure

styles. Both enclosures are epoxy coated aluminum castings.

All sales subject to standard terms and conditions of sale. I&M009-10007- (250-2248E) 10/12
