Abrégé

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). Advantageously, the pneumatic connector (36) defines at least one connection channel (44) placing the distribution valve (32) in fluidic connection with the control means (40), wherein inside the connection channel (44) at least one anti- explosion means (52) is inserted, positioned coaxially to the connection channel (44) so as to reduce the through cross-section (56) thereof by a predefined length of the connection channel (44), said through cross-section (56) being confined on an outer circular crown of the connection channel (44), delimited between an inner side wall (60) of the connection channel (44) and an external lateral wall (64) of the anti-explosion means (52).

Abrégé

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.

Abrégé

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.

A rotary switch (4) comprising a body (8) housing inside itself a rotating shaft (12) operatively connected to a valve or actuator. The switch (4) further comprises a cover (20), associated to the body (8) by threaded coupling means (36), provided with an indicator (28) swivelling integrally with the shaft (12), so that it enables visual signalling of the angular position and/or operating status of the shaft (12). The switch (4) comprises centering means (56), mechanically distinct from the threaded coupling means (36), which ensure the centering of the cover (20) in relation to the body (8) and the coaxial relation between the cover (20) and the rotating shaft (12).

A signal actuation device (4) for switches (16) with high resistance to corrosion. The device (4) allows the assembly of a revolving activation element (20) without requiring the use of brasses or bushes and also allows the earthing of the device by applying an earth wire directly to the device body (8).
