Installation for safety applications:
Use only switches marked with the symbol
next to the product code. Always connect the safety circuit to the NC contacts (normally closed
contacts: 11-12, 21-22 or 31-32) as required by EN ISO 14119, paragraph 5.4 for specific interlock applications and EN ISO 13849-2 tables D3
(well-tried components) and D.8 (fault exclusions) for safety applications in general. Actuate the switch at least up to the positive opening
travel shown in the travel diagrams on page 216. Actuate the switch at least with the positive opening force, reported in brackets below each
article, next to the actuating force value.
If not expressly indicated in this chapter, for correct installation and utilization of all articles see the instructions given on pages
211 to 222.

FK series position switches with reset
Pizzato Elettrica has developed a reset device code W3 to make perfectly simultaneous the actuator and the contact block tripping. This new
device consists in a block to be mounted between the body and the head of the switch that can be rotated independently from the head. This
new device offers the following advantages:

IMPORTANT
For safety applications: join only switches and actuators
marked with symbol next to the product code.
For more information about safety applications see details on
page 211.
Increased actuating forceIncreased actuating force
The switch can be delivered with increased
actuating force (option W4). Ideal for vibration applications.
Actuators Actuating force
01, 14, 15, 16 7 N
02, 05 6 N
07 3.5 N
30 … 57 0.08 Nm
To order the switch with reset and increased
actuating force, replace the -W3 option with -W4
in the order code.
Example: FK 3301-W3M1 FK 3301-W4M1
Separate actuators
IMPORTANT: These separate actuators can be used only with items of the FR, FM, FX, FZ and FK series.
