摘要:
A switch monitors an access (A) to a machine or plant. The switch has a switching device (3) housing switching mechanism, an actuator device (2), and a push-button panel (12). The housing switching mechanism operatively connects to one or more circuits of the machine or plant. The actuator device (2) interacts with the switching mechanism at the opening/closing of the access (A). The push-button panel (12) has a shell (14) provided with controls (13) designed to operate on one or more of the circuits of the machine or plant. The shell anchors to a fixed part (F) of the access (A) to allow the rotation of the shell (14) around a rotation axis (R), so as to vary an orientation of the shell (14) with respect to the switching device (3) and/or to control and/or service circuits.

An adapter for mounting electric units to be wired to an electric system comprises a hollow anchoring body (10) having an upper portion (17) with a hole (12) for the passage of a driving control (6), a lower portion (16) removably coupled with the upper portion (17), a pair of reciprocally opposite side faces (15) at least partially open to allow the wires to access to electric units (2) housed into the anchoring body (10), means (14) for removably mounting the anchoring body (10) to a support (R), first holding means (27) adapted to removably fix the electric unit (2) to the bottom wall (13) of the lower portion (16). The first holding means (27) comprise at least one first and one second recesses (29) formed in the bottom wall (13) at respective open side faces (15) to house and snap-hold the electric unit (2).
摘要:
A safety switch with a lock-out device including a switching unit, switching elements and actuating elements. The switching elements and the actuating elements are electronic and are respectively associated with a first communication element and a second communication element adapted to remote communicating therebetween by a signal and to allow the switching elements to discriminate the presence of an operating unit close to the switching unit. The switching unit includes a movable guard having a shielding element adapted to interpose itself between the communication elements when the guard is into the active position to avoid the transmission of the signal and the closing of the switching elements.

A safety switch with a lock-out device comprises a switching unit (2) adapted to be anchored to a fixed part of a structure and provided with switching means adapted to be operatively connected with at least the power supply circuit of the plant to be controlled for the opening/closing thereof, an operating unit (3) adapted to be anchored to a movable part of the structure and having actuating means (5) adapted to interact with the switching means upon the closing of the movable part on the fixed part to enable the closing of the power supply circuit, a lock-out device (16) associated with the switching unit (2) and having a guard (17) movable between an inactive position adapted to allow the interaction between the switching means and the actuating means (5) and an active position wherein the interaction is avoided. The switching means and the actuating means (5) are of the electronic type and are respectively associated with a first communication element (6) and a second communication element (7) adapted to remote communicating therebetween by means of a presence signal and to allow the switching means to discriminate the presence of the operating unit (3) close to the switching unit (2). The movable guard (17) comprises a shielding element (20) adapted to interpose itself between the communication elements (6, 7) when the guard (17) is into the active position to avoid the transmission of the signal and the closing of the switching means.
摘要:
A protection assembly with an operating knob (1) for an electrical potentiometer comprises a substantially tubular housing (2) defining a longitudinal axis (L), an electrical adjustment device (3) held within the housing (2) and having an adjustment shaft (4) rotating about the longitudinal axis (L) and an internal variable resistor interacting with a longitudinal end (5) of the shaft (4), an operating knob (6) attached to the other end (7) of the shaft (4), limit stop means (8) for restricting the rotation of the shaft (4) within a predetermined maximum angle of rotation (a). The knob (6) comprises an annular anchoring member (9), which is designed to be removably coupled to the housing (2) and an operating member (10) coupled to the shaft (4) and rotating relative to the anchoring member (9). The anchoring member (9) and the operating member (10) have mutually facing cylindrical surfaces (11, 12), with said limit stop means (8) interposed therebetween to limit the infiltration of external impurities.

A potentiometer comprises a cylindrical case (2) having an upper edge portion (3) and housing an electric adjustment device (5) enclosing a variable resistance, means (8) for the electrical connection of the electrical adjustment device (5) to the circuit to be controlled, a knob (9) partially inserted into the case (2), a drive shaft (10) at least partially housed in the case (2) with a first end (11) associated with the knob (9) to be integral in rotation therewith and a second end (12) interacting with the variable resistance to vary the instantaneous value thereof upon the rotation of the shaft (10). The electric adjustment device (5) comprises a box-like housing (14) coupled to the electrical connection means (8) and housing the variable resistance and having a longitudinal passing-through hole (15) suitable for snugly fit the second end (12) of the shaft (10).
