Abstract: A relay with an intermediate alert mechanism and a method for producing an intermediate alert in association with a relay. The relay comprises an input sampling module configured to detect a parameter of a source to be monitored; a processing module configured to determine a working range based on a threshold level and a working condition, and the processing module further configured to automatically determine at least one intermediate level within the working range based on the threshold level. The processing module causes the transmission of an intermediate trigger signal when the detected value of the parameter reaches the intermediate level.

Abstract: A relay control device for a relay module and a relay module are provided, the relay control device comprising, one or more docks, each dock specifically adapted to mate with a modular contact device and comprising a first mating portion for the mating; one or more power terminals for coupling an energy source to energise the relay control device; an electromagnet disposed in a housing of the relay control device, the electromagnet comprising an electromagnetic coil; and a core, wherein the electromagnetic coil and the core are configured to cooperate with each other upon energization of the relay control device to provide a push mechanism of the relay control device to switch a state of at least one modular contact device.

Abstract: A plug and socket assembly comprising (i) a socket that includes a mating means disposed thereon, and an electrical contact on the socket, and (ii) a plug that includes a matching means for mating with the mating means disposed on the socket, and a conducting terminal for coupling electrically to the electrical contact on the socket. The matching means is configured to be adjustable between a compatible mode and an incompatible mode. When in the compatible mode, the matching means allows the electrical contact to contact the conducting terminal, and when in the incompatible mode, the matching means substantially prevents the electrical contact from contacting the conducting terminal.

Abstract: An optical traffic signal column including stacked levels fixed to one another by rotation. The base of each level includes, distributed along its periphery, oblong passages and fixed connectors. The conductors include rods each having two ends angularly offset from one another, and including a common conducting rod and a stage-specific conducting rod. The connector rods are identical and respectively fix the bottom of a conducting rod of the relevant level and the top of the respective conducting rod of an adjacent level, the angular offset between the two fixing points corresponding to that of ends of the conducting rods. The conducting rods are mutually arranged and mounted to effect, from one level to the next level, an essentially identical angular position of the common conducting rods and an angular offset of the stage-specific conducting rods.

Abstract: The invention relates to a signaling column with levels which are assembled by a relative pivoting limited in amplitude and interconnected by axially-extending conductors. The body of a level includes a locking bar which extends axially to penetrate an opening in an adjacent level and abuts an edge of the opening on a rotation attempt. The ends of the bar may be displaced and the opening is of such a size as to accommodate the top end of a relevant bar and the bottom end of the bar above.

Abstract: The invention relates to a signalling column with levels which are assembled by means of a relative pivoting limited in amplitude and interconnected by means of axially-extending conductors. The body of a level (A) has a locking bar (30) which extends axially to penetrate an opening (23) in the adjacent level and abuts an edge of said opening on a rotation attempt. The ends (30a, 30b) of the bar may be displaced and the opening is of such a size as to accommodate the top end of the relevant bar and the bottom end of the bar above.

Abstract: The invention relates to an, in particular, optical traffic signal column composed of stacked levels and fixed to one another by rotation. The base of each level has, distributed along its periphery, oblong passages (12) and fixed connectors (30). The conductors (20) are rods each having two ends (21, 23) angularly offset from one another, and the common rod (20C) is identical to the other rods (20A). The connectors are identical and they respectively fix the bottom (23) of a rod (20) of the relevant level and the top (21) of the respective rod of an adjacent level, the angular offset between the two fixing points corresponding to that of the ends of a rod. The connectors (30) and the rods (20A, 20C) are mutually arranged and mounted in order to effect, from one level to the other, an essentially identical angular positioning of the common rods and an angular offset of the other rods.

Abstract: A switch including a switch box housing an electrical switching assembly, the box having a front part, a middle part and a back part that has two lateral wing-shaped walls, with a detection head located in the front part and a removable cable connector located in the back part for connecting a cable to output contacts, wherein the removable cable connector is located in the switch box between the wing-shaped walls, and has a body having at least one surface for releasable attachment to the switch box by the locking mechanism, and the electrical switching assembly and the body of the removable cable connector are substantially identical in width and depth to a transverse cross-sectional dimension of the switch box, and are housed for removable insertion one behind the other lengthwise in the switch box for electrical connection therebetween.

Abstract: A position switch whose box houses a switch assembly that can be maneuvered by an activation head holding a push button and located in a recess on one surface of the box so that it can be angularly adjusted at regular intervals. The head has a tubular bearing surface facing the box and in which a plunger slides for actuating the switch assembly. The bearing surface has notches at regular intervals for alignment with corresponding notches in the box recess. A lockable fork retains the head in position.

Abstract: Switch, more specifically a position switch, whose box is roughly prismatic. The box 10 has wings 15a,16a,13a at the back that define the external template of the box and the wings of a housing A in which a connector 30 fits. The connector is fitted so that it is detachable from the housing and has a built-in body between the wings 15a,16a,13a and has at least one surface 35,36 defining the external template of the box.
