travel shown in the travels diagrams on page 134. The switch must be actuated at least with the positive opening force, shown in brackets,
underneath each article, near the value of the actuating force.
If not expressly indicated in this chapter, for correct installation and utilization of all articles see the instructions given on pages

Introduction
When the FT series safety switches with reset are operated they remain switched and they reset electrically through the integrated
solenoid. Thanks to this feature it’s possible to remote reset the switch without being physically near it. They are available with
different actuators and are adapt to many applications, particularly to the lift, the over-speed governor and generally to the safety
field. Some items can also be supplied with the manual reset.
4
According to EN 81-20 and EN 81-50
• Safaty contacts according
to EN 60947-5-1, encl. K.
• Protection degree higher
than IP4x.
• All switches are in
compliance with the
requirements set by the
new standards on safety
contacts.
Reduced actuating force (E26/E28)
On request FT series
switches can be supplied
with a reduced actuating
force.

Adjustment system version (C, D, E, F housing)
A B C
Pizzato Elettrica introduces a new integrated adjustment system designed purposely for
applications on over-speed devices.
The system allows a fine and sensitive adjustment of the switch position along its vertical axis.
Characteristics:
- Easy installation and adjustment
- Accurate vertical adjustment
- Wide adjustment travel (up to 4 mm)
)
- Unlosable components
)
Operation:
)
A
Make a hole in the fixing plate to insert the adjusting pin on the back of the switch. Apply the
)
switch to the over-speed device without blocking the two fixing screws.
B
)
Adjust the switch position by the screw on the front.
C
Finally lock the switch body to the over-speed device.
Safety lever
The adjustable lever code 56
(and variants) is supplied with
an indentation which blocks
the lever slipping in case of
fixing screw release.
Adjustable levers
In switches with revolving lever it is
10°
possible to adjust the
lever with 10° steps for
the whole 360° range.
The positive movement
transmission is always
guaranteed thanks
to the particular
geometrical coupling
between the lever and
the revolving shaft as
prescribed for safety
applications by the
German standard
BG-GS-ET-15.
Conduit entries
Switches with conduit
entries in several directions
are available, for applications also in restricted
spaces.
Overturning levers
obtain two different work plans of the lever.
Rotating heads
In all switches, it is possible to rotate the head in 90° steps.
It’s possible
to fasten
the lever on
switches on
straight or
reverse side,
maintaining
the positive
coupling.
In this way it
is possible to
