General characteristics
Available versions
Pizzato Elettrica new emergency pushbuttons, which function is to
allow the operator to stop a device or a machine in case of danger
by pushing the same button, are classified by their release modality:
push-pull, turn to release and key release.
State indication
The push-pull and turn to release emergency pushbutton can be
provided with a visual state indication through a mechanical indicator.
The state is indicated by green colour when the pushbutton is not
actuated and red colour when it is actuated.
Protection degree IP67 and IP69K
Designed to be employed also in
severe environment conditions, Pizzato
Elettrica pushbuttons have protection
degree IP67 and IP69K, suitable for use
in machineries subjected to intense
washing with high pressure and high
temperature water jets.
Mechanical endurance
All emergency pushbuttons have been tested to endure 300.000
mechanical cycles.
Emergency pushbuttons
Installation for safety applications:
Use only switches marked with the symbol . The safety circuit must always be
connected with the NC contacts (normally closed contacts: 1-2) as stated in the
standard EN 60947-5-1, encl. K, par. 2.
In conformity with standards:
IEC 60947-1, IEC 60947-5-1, IEC 60947-5-5, IEC 60204-1, EN 60947-1, EN 60947-5-1,
EN 60947-5-5, EN 60204-1, EN ISO 13850, UL 508, CSA 22-2 N°14
In conformity with requirements requested by:
Low Voltage Directive 2006/95/EC, Machinery Directive 2006/42/EC and
Electromagnetic Compatibility 2004/108/EC.
Positive contact opening in conformity with standards:
IEC 60947-5-1, EN 60947-5-1, VDE 0660-206.
Temperature range extended
Special versions can be ordered
for use in environments where the
temperature changes from +80°C
to -40°C.
They can be installed inside cold stores, sterilizers or other equipments
with very low ambient temperature. Special materials that have been
used to realize these versions, maintain unchanged their features also
in these conditions, widening the installation possibilities.
