Safety switch with tumbler, door handles

Complete portfolio of high-performance components and systems for human safety.



Safety switch with guard locking, door handles

To protect the people and machines, it is important to secure danger zone in such a way that people cannot enter the area.

These areas are protected by means of door interlocks. These are designed as safety switches with guard locking and also as a feature in a door handle.

General information about safety interlocks and switches:

Safety switches of the NG series are mainly used on machines where a hazard exists, even after the machine's standstill control has been triggered. Mechanical parts such as guide rollers, saw blades, etc. could still be moving after the machine has been switched off, or parts of the machine could still be hot or under pressure. The switches can thus also be used if you only want to open individual protective devices under certain conditions.


- A series connection of several switches is possible. (Up to 32 pieces)

- Safety levels PL e according to EN ISO13849-1

- SIL 3 according to EN 62061 guaranteed.

Series NS with electromagnet and RFID technology:

The NS series switches are suitable for controlling protective devices on machines where - even after the machine's stop signal has been triggered - a hazard still exists: dangerous moving parts could still be moving after the machine has been switched off, or parts of the machine could still be hot or under pressure.


"Lock-out" device LK S for NS series safety switches:

The device is made entirely of metal and is attached to the side of the holes of the NS devices without an additional mounting plate or bracket.

The slide not only closes the insertion opening for the actuator, but also serves as a shield for RFID receiver antenna of the NS switch and thus provides double protection against unintentional closing of the safety guard and early restart of the machine. This is particularly effective, for example, on machines where a low-code actuator is installed, and prevents any attempt to bypass the switch.

When the slide is raised, an elongated eyelet appears at the top of the device into which you can hook up to 5 padlocks.

Safety sensors


  • High switching reproducibility
  • Reliable sensing
  • Large range
  • Robust housing
  • Easy installation and adjustment
  • High dirt resistance
  • High protection classes


General information about safety sensors:

Thanks to their extremely compact design and non-contact RFID technology, the ST series sensors guarantee a long-term durable solution for frequently operated safety devices. They can also be used in difficult environmental conditions.

The choice of 3 different actuators with different mounting and actuation directions makes these sensors particularly

versatile. They are suitable for installation on almost all types of machines and large as well as small guards.

General information about security door handles:

New, revolutionary safety door handle from Pizzato Elettrica

In the new P-KUBE Krome series from Pizzato Elettrica, integrated LED indicators provide information on the status of the safety device with a visual signal.

With the optional built-in command button and the optional integrated indicator light, the robust ergonomic safety door handle P-Kube Krome from Pizzato offers a fully integrated visual status and operating status signaling.

Thanks to RGB technology, the signal colors for the operating status of the system can be freely selected by the user.

Special features of the series P-KUBE Krome:

  • Compatible with safety switches of the series NG and NS (+ RFID technology according to EN ISO 144119)
  • Reduction of storage costs (handle on swing and sliding doors optionally right or left, without parts replacement)
  • Long service life due to robust design (mounting plate made of 5 mm steel)
  • Manipulation-proof due to snap-in protective caps
  • Manipulation-proof due to RFID-supported actuator with high coding level
  • Integrated, illuminated pushbutton for various functions: Request-Open, Close, Reset ...
  • Local status indication at guard by integrated RGB LED
  • Flexible signal color of handle
