Z/T and E.95 range position switches are suitable for sliding and hinged safety guards, which need to be closed to ensure the necessary operational security.
In combination with AES and/or AZR range safety monitoring modules all position switches class 1 shown in this chapter achieve Control Category 3 or 4 to EN 954-1.
Further applications for positions switches class 1 are most varied positioning duties. The variety of requirements to be found in practice can be met in detail by means of a wide range of actuating elements.
Design and mode of operation:
On the position switches class 1 the guarding device and the positive break NC contact are positively linked.
Schmersal make both standard and AS-i Safety at Work position switches with safety function.

Pull-wire emergency stop pushbuttons are mounted on machines and sections of plants which cannot be protected by guards. In contrast to mushroom head Emergency stop push buttons, on pull-wire switches the Emergency Stop command can be initiated from any point on the wire.
In combination with one of the AES and AZR range safety monitoring modules, see chapter 10.3, ZS range pull-wire emergency stop switches can be used for Control Category 3 or 4 to EN 954-1.
Design and mode of operation:
All of the pull-wire emergency stop switches conform to European Standard EN 418. They have a positive linkage between the NC contacts and the wire rope. The pull-wire emergency stop switches are brought into the operational condition by pre-tensioning the wire, i.e. the NC contacts are then closed and the NO contacts open.
Schmersal make both standard and AS-i Safety at Work pull-wire emergency stop switches.

Manufacturer of safety switches FR series
Pizzato Elettrica switches of the FR series with separate industrial actuator reach the 4th generation. These switches are ideal for gates, protections, carter and all different guards which protect dangerous parts of a machine. The stainless steel actuator is fixed to the mobile section of the protection in order that every time the protection is opened the actuator is pulled out of the switch. A particular mechanism assures the positive opening of the electrical contacts by the pulling out of the actuator. These switches are easy to install and can be applied to any type of protection (hinged, sliding or removable). Furthermore the possibility of operating the switch only with the specific actuator assures that the machine can start again only when the guard is closed.
Pizzato Elettrica switches of the FR series distinguish themselves for the following characteristics:
Rotating heads: by unscrewing the fixing screw the head can be rotated in 90° steps.
Not detachable heads: the head 93 is perfectly interchangeable and compatible with the previous head 92 but it has the advantage that it is not detachable from the body, nonetheless it can rotate in 90° steps (Pizzato Elettrica patent). Practically speaking the new head is safer because its not possible to damage it during the installation.
The FR series complements the range of products that Pizzato Elettrica can offer to its customers. For further information, please visit the website www.pizzato.com or ask for the relative documentation. |

These protection switches are ideal to control gates, sliding doors and other guards protecting dangerous parts of machine. The stainless steel actuator is fastened to the moving part of the guard, so it is removed from the switch on every opening of the guard. The switch mechanism guarantees that removing the actuator forces the positive opening of the electrical contacts. Easy to install, these switches can be applied to any kind of protection (with hinge, sliding and removable ones). Besides, the possibility to actuate the switch only with its actuator guarantees that the machine can be restarted only when the guard has been closed.
- Polymer housing, three M20 or M16 knock out conduit entries
- Protection degree IP67
- 6 contact blocks available
- 8 stainless steel industrial actuators available
- 30 N actuator extraction force versions
- Silver contacts gold plated versions
- Cylindrical or slotted fixing holes

Application:
Safety switches with separate supplier of actuator are suitable for sliding, hinged and particularly removable safety guards, which need to be closed to ensure the necessary operational security. They are also suitable for professional fitting on profile sections and existing equipment.
In combination with safety control modules all safety switches with class 2 shown in this chapter achieve Control Category 3 or 4 to EN 954-1.
Design and mode of operation:
On the safety switches with class 2, the switching element is not physically connected to the actuator but functionally brought together or separated for switching. When the guarding device is opened, the actuator is separated from the base unit. In the process, NC contacts are positively opened and NO contacts closed.
Enclosure rating of all the safety switches is IP 67. The safety switches can be fitted in any desired mounting position.
Schmersal make both standard and AS-i Safety at Work safety switches with separate actuator.
