CE marking
SUCO pressure switches rated
with an operating limit of 250 V
are covered by the Low Voltage
Directive 73/23/EC.
An EC Declaration of Conformi-
ty has been issued for these
pressure switches and is on file
at our offices. The correspondi-
ng switches bear the CE mark
in our catalogue.
Mounting options
for wall or manifold
mounting enable easy,
free-maintenance
installation.
Easily user-adjustable
switching point.
High overpressure safety.
Socket device allows
easy assembly on site.

Degree of protection IP65
The type approval does not apply without restriction to all environmental conditions. It is the responsi-
bility of the user to check whether the electrical connection complies with regulations other than those
stated, and whether it can be used for special applications which could not be foreseen by us.
Warning !
When using oxygen, the relevant accident prevention regulations must be observed. In addition,
we recommend that a maximum operating pressure of 10 bar is not exceeded.
Piston pressure switches are only to a limited extent suitable for use with gases.
See explanation on page 9.
Our pressure switches are
also available with factory
pre-set switching points.
