Abstract: A rotary switch (4) comprising a switch body (8) which identifies an inner space (10) which rotatably houses a shaft (12) operatively connected to an actuator device external to the switch (4), a distribution valve (32) positioned outside said inner space (10), a pneumatic connector (36) and at least one control means (40), such as a solenoid, operatively connected to the pneumatic connector (36), arranged in the inner space (10). The control means (40) is operatively connected to the external device, the distribution valve (32) is operatively connected to the control means (40) by means of the pneumatic connector (36).

Abstract: A rotary valve position indicator utilizes a magnet keyed to a shaft, and a magnetic field sensor mounted beside the magnet, to indicate the angular position of the shaft. A magnetic pole sensor detects the initial polarity of the magnet during setup to determine how to correlate the output readings of the magnetic field sensor with the position of the valve. The sensors are located so they permit the shaft to extend through to a mechanical visual indicator.

Abstract: A rotary switch comprising a body housing inside itself a rotating shaft operatively connected to a valve or actuator. The switch further comprises a cover, associated to the body by threaded coupling means, provided with an indicator swivelling integrally with the shaft, so that it enables visual signalling of the angular position and/or operating status of the shaft. The switch comprises centering means, mechanically distinct from the threaded coupling means, which ensure the centering of the cover in relation to the body and the coaxial relation between the cover and the rotating shaft.

Abstract: A switch device includes a container of the hermetic type, at least one switch contained inside the hermetic container, and actuation devices at least partially contained inside the container and suitable to actively select the switch. The actuation devices have at least one internal ferromagnetic element, moving inside the container so as to influence an actuation button of the switch, and a transmission body having a first extremity which interfaces in contact with said internal ferromagnetic element and a second extremity which interfaces in contact with said actuation button. The transmission body is a rigid body which receives and transmits the movement of the internal ferromagnetic element from a rest position in which it does not cause the actuation button to be actuated and a functioning position in which it presses and acts on the actuation button by contact.

Abstract: A switch device comprising a container of the hermetic type, at least one switch contained inside the hermetic container, actuation devices at least partially contained inside the container and suitable to actively select the switch. Advantageously, the actuation devices comprise at least one internal ferromagnetic element, moving inside the container so as to influence an actuation button of the switch, and comprising in addition a transmission body having a first extremity which interfaces in contact with said internal ferromagnetic element and a second extremity which interfaces in contact with said actuation button. The transmission body is a rigid body which receives and transmits the movement of the internal ferromagnetic element from a rest position in which it does not cause the actuation button (28) to be actuated and a functioning position in which it presses and acts on the actuation button by contact.

Abstract: A handling device is associable to an on-off valve and comprises handling means suitable for being gripped by an operator, a connection device for supporting said handling means, spring back means for returning said valve from the open configuration to the closed configuration (or vice versa) and a positioning and support device through which the handling means support the spring back means in a position suitable for operating properly.
