25PS, 42PS, 44PS, 45PS and 46PS

Series Pressure Switches

for 2.5 million cycles.† In applica-

tions such as split room air condi-

tioning systems, the 46PS as a head

pressure control can result in signifi-

cant cost savings when used instead

of a pilot duty switch and relay.

able in SPST and SPDT, offers a

variety of pressure settings, port

fittings and electrical connections.

Key Features

• SPST or SPDT switch with normally

open or closed contacts

Ap p lic a t io n s

• Electrically rated to 600 Vac (44/45PS)

• High cycle life capability (42/44PS)

This line of pressure switches is

designed for direct control of

motors and other demanding loads

requiring precise pressure settings.

Op e ra t io n

• Factory calibrated pressure setpoints

from vacuum to 750 psig

The snap-acting stainless steel

diaphragm reverses its curvature

when pressurized to a customer

specified value. When the disc

snaps, it opens or closes a set of

electrical contacts by means of a

transfer pin. Resetting the switch

occurs automatically when pressure

drops below a preset value.

• Snap-acting stainless steel

hermetically sealed sensor

Extended electrical capacities and

life cycles, in both environmentally

sealed and unsealed configurations,

encourage usage in the most rigor-

ous fan cycling and high/low

• Available with environmentally

sealed switch

• High current capability

pressure protection applications.

The 25PS series is an automatic

reset pressure switch designed to

meet a broad variety of application

requirements. This series is avail-

The 46PS pressure switch is capable

of breaking 2 amp loads at 480 Vac
