AVAILABLE SWITCH MECHANISMS AND APPLICATION DATA
Series 75 switches are available with several different switch mechanisms – each designed for specific service conditions. Brief
descriptions of the individual switch mechanisms and their application are given below.
For electrical ratings, see bulletin BE 42-120.
Mercury switches – Series A & E
Hermetically sealed switches – Series F, HS, W & X
Mercury switches offer the advantage of quick visual
inspection of contact conditions.
Series A switches are heavy duty units with high load
carrying capability.
Series E switches are specifically designed to provide
greater vibration resistance.
Hermetically sealed switches are for use in special
applications where hermetically sealed contacts are
required.
The Series F switch is well suited for use in applications
where the process temperature does not exceed 400°C
(750°F).
The Series HS switch features a positively pressurized
capsule for the entire swicht mechanism including contacts.
It is suited for use in applications where the process
temperature does not exceed 290°C (550°F). It is available
with easy access terminals. These switches are ideal where
salt and other corrosive atmospheres are found.
Series W have silverplated and Series X have goldplated
contacts; both suitable for liquid temperatures up to 230°C
(450°F).
Mercury
High temperature mercury switches – Series 2 & 3
Available with all the features of the standard series of
mercury switches. Series 2 and 3 feature nickel/copper bare
wire and ceramic beaded insulation to allow use in
applications where the process temperature does not
exceed 400°C (750°F).
Series 2 switches correspond to series E switches.
Series 3 switches correspond to series A switches.
High temperature
mercury
Dry contact switches – Series B, C, D & U
These switches are specified in applications where mercury
must be avoided – such as in nuclear power plant
installations.
Series B and C switches are general purpose units with
electrical ratings dependent upon maximum liquid
temperature.
Series D switches are designed for high DC current
applications.
Series U have gold alloy contacts.
Dry contact

Series W & X
Series "HS"
with terminal block
Pneumatic Switches – Series J & K
Pneumatic switches are employed in process industry
applications where electrical power is not available or to
satisfy safety requirements.
The Series J bleed-type switch is intended for general
purpose applications.
Series K units are specially designed to provide non-bleed
operation with a high degree of vibration resistance.
Pneumatic
AVAILABLE SWITCH ENCLOSURES
Electric switches – non hazardous area = IP 65/NEMA 4X weather resistant.
Electric switches – hazardous area
= CENELEC/BASEEFA (IP 66)/NEMA 7/9 (IP 65) explosion proof.
Pneumatic switches
= NEMA 3R (IP 53) weather resistant.
Consult the factory for drain/heater options.
All housings are standard available with anti corrosive coating.

PRINCIPLE OF OPERATION
A permanent magnet ① is attached to a pivoted switch
actuator ②. As the float/ displacer ③ rises following the
liquid level, it raises the attraction sleeve ④ into the field of
the magnet, which then snaps against the non-magnetic
enclosing tube ⑤, actuating the switch. The enclosing tube
provides a static pressure boundary between the switch
mechanism and the process. On a falling level, an inconel
spring retracts the magnet, deactivating the switch.
