Definitions

  • the present description relates to the technical field of electrical installations and, more particularly, it relates to a changeover switch with rocking control member.
  • modular electric apparatuses such as modular switches or modular sockets - each designed to carry out a predetermined function - is widespread in modern electrical systems such as for example, household electric installation systems.
  • Relatively more complex assemblies may be obtained by conveniently combining such modular apparatuses with one another, such assemblies making available the sum of the various functions.
  • a changeover switch 1 of the known art is depicted in figure 1 , which shows a side view of the changeover switch 1, and in figure 2 , which shows an exploded axonometric view of the changeover switch 1.
  • the changeover switch 1 comprises a support structure 2 made of insulating material, or case 2, having a box-like shape and defining an inner compartment for housing and supporting electromechanical components belonging to the changeover switch 1.
  • the changeover switch 1 further comprises two sliding buttons 3a, 3b, each of which is under a respective covering member 4a, 4b, which is mechanically coupled, for example snap coupled, with the associated sliding button 3a, 3b so as to slide together therewith.
  • the sliding buttons 3a, 3b are adapted and configured to slide with respect to case 2 along a respective sliding axis.
  • the sliding button 3a in particular is adapted to slide along axis A-A while the sliding button 3b is adapted to slide along axis B-B.
  • the changeover switch 1 comprises two movable contacts 7a, 7b and two fixed contacts 8a, 8b.
  • the movable contacts 7a, 7b are arranged on two opposite ends of an electrically conductive rocking switching member 6 comprised in the changeover switch 1 and having a central portion 6c resting on an electrically conductive support fulcrum 9.
  • the support fulcrum 9 is made according to the teachings of European Patent EP2304749 B1 .
  • a user may operate the changeover switch 1 by means of the actuation buttons 3a, 3b by sliding the aforesaid buttons 3a, 3b by applying a manual pressure force thereon in order to cause a rotation of the rocking switching member 6.
  • the latter has three stable angular positions:
  • the changeover switch 1 further comprises a rocking control member 5 operatively coupled, and in particular hinged, to both buttons 3a, 3b and which may be moved, in particular rotated, by means of the aforesaid buttons 3a, 3b so as to cause the rocking switching member 6 to selectively take on one of the three stable angular positions.
  • a support frame 10 made of electrically insulating material is also comprised in the changeover switch 1, the support frame being inserted in case 2 to support the buttons 3a, 3b and the rocking control member 5. From a functional perspective, the support frame 10 may be considered part of case 2, given that it also performs a housing and support function for certain components of the changeover switch 1.
  • a changeover switch 1 of the above-described type has been widely used to date for example, for generating electric control signals in order to raise or lower rolling shutters or automated blinds associated with doors or windows in residential or commercial buildings.
  • a first drawback is given by the fact that the changeover switch 1 has a relatively high axial volume.
  • a second drawback is given by the fact that the manual pressure exerted on one of the two buttons 3a, 3b to push it towards case 2 automatically causes a sliding of the other of the two buttons in the direction moving away from case 2, whereby when the rocking switching member 6 is in one of the angular end of stroke positions, one button is lowered while the other button is raised, thus causing an unpleasant appearance due to the misalignment between the buttons 3a, 3b.
  • the fact that the movement of one of the two buttons also results in the movement of the other button moreover increases the overall inertia of the kinematic mechanism perceived by a user when the user manually operates the changeover switch 1.
  • a third drawback is given by the fact that starting from this circumstance in which the rocking switching member 6 is in one of the two angular end of stroke positions, if there is a desire to bring said rocking member 6 into the central angular position, there is a need to exert a manual pressure on the button which is higher with respect to the other one. If the manual pressure force applied to the button is not sufficiently accurately controlled, the central angular position may be overtaken and the rocking switching member 6 may be undesirably brought into the other of the two angular end of stroke positions.
  • modular electric apparatus means an electric apparatus intended to be installed in a wall mounting frame placed side-by-side with other electric apparatuses of the same type or other modular electric apparatuses in general, such as for example, electric sockets or sockets of other electric control apparatuses for controlling and distributing electric power.
  • the changeover switch 100 can be operated manually by a user and can be used for example, however without any limitation, to control an electromechanical device electrically connected thereto, such as for example, a rolling shutter or automated blind or curtain, or to control an optical signaling device, for example an optical signaling device adapted to take on three different signaling statuses.

  • final forward position means an end of stroke position in the approaching movement of the side buttons 30a, 30b to case 20
  • backward position means an end of stroke position in the distancing movement of the side buttons 30a, 30b from case 20.
  • the terms “forward” and “backward” refer to the position of the side buttons 30a, 30b with respect to case 20.
  • the side buttons 30a, 30b are independent from each other in the translation along the respective sliding axes A-A, B-B, in particular they are mechanically directly or indirectly coupled to case 20 so as to be independent from each other in translation.
  • the first side button 30a and the second side button 30b are adapted and configured to translate with respect to case 20 along the respective sliding axes A-A, B-B independently from each other.
  • the changeover switch 100 comprises, for each of the two side buttons 30a, 30b, at least one elastic return element 32a, 32b configured to push the respective side button 30a, 30b into the initial backward position.

  • the side buttons 30a, 30b preferably are made of electrically insulating material, e.g. plastic.
  • Case 20 of the changeover switch 100 comprises a tubular side wall 22 and a bottom wall 23 joined to the side wall 22. Case 20 comprises an open side 24 opposite the bottom wall 23.
  • the tubular side wall 22 and the bottom wall 23 delimit an inner compartment adapted to accommodate the electromechanical components of the changeover switch 100 and at least three electric connecting terminals 73a, 73b, 73c, for example three screw operated clamps.
  • the changeover switch 1 further comprises a rocking control member 50 adapted to be rotated in two opposite directions by means of the first side button 30a and the second side button 30b, respectively.
  • the side buttons 30a, 30b are independent from the rocking control member 50, for example the changeover switch 1 being devoid of any direct mechanical constraint between the side buttons 30a, 30b and the rocking control member.
  • the side buttons 30a, 30b do not interfere in abutment with the rocking control member 50 in the initial backward position thereof, said side buttons 30a, 30b being adapted and configured to come into contact with the rocking control member 50 from a certain point onward, along the sliding thereof from the initial backward position to the final forward position thereof.

  • the support fulcrum 90 is made of bent and cut metal sheet, for example.
  • the support fulcrum 90 preferably comprises a support and contact portion 91 shaped so as to define a groove, for example having a V-shaped cross section.
  • the support fulcrum 90 more preferably further comprises a connection portion 93 which forms part of a connecting terminal 73c of the changeover switch 100.
  • the second end portion 62 of the rocking switching member 60 rests on the support fulcrum 90, in particular on the support and contact portion 91.
  • the rocking switching member 60 is an L-shaped plate having a larger base which rests on the support fulcrum 90 and an arm which is narrower than the base and to which the movable contacts 70a, 70b are fastened.

  • the changeover switch 100 comprises a support frame 21 inserted in case 20, to which a given number of components of the changeover switch 100 are fastened, such as for example, the side buttons 30a, 30b and the rocking actuator 50.
  • the support frame 21 is for example, snappingly fitted in case 20.
  • the support frame 21 preferably is made of electrically insulating material, e.g. plastic. From a functional perspective, the support frame 21 may be considered part of case 20 given that it also performs a housing and support function for certain components of the changeover switch 100. It is therefore correct to affirm that case 20 comprises the support frame 21.
  • the support frame 21 comprises one or more side walls 25, 26 and a bottom wall 27.
  • An opening 28 adapted to be crossed by the fixed contacts 80a, 80b and by the movable contacts 70a, 70b preferably is defined in the bottom wall 27.
  • the aforesaid opening 27 preferably is crossed by the rocking switching member 60 and by the contact-holder supports 83a, 83b of the fixed contacts 80a, 80b so that the fixed contacts 80a, 80b and the movable contacts 70a, 70b are arranged in the support frame 21.
  • the elastic return elements 32a, 32b have an end portion which reacts against the bottom wall 27 of the support frame 21 and which preferably rests on the latter. It is worth noting that the elastic return elements 32a, 32b in this embodiment are operatively interposed between the support frame 21 and the side buttons 30a, 30b.
  • the provision of the support frame 21 has the advantage of simplifying the assembly of the changeover switch 100 and of allowing the use of the space available in case 20 to be optimized. In the practice, such a support frame 21 causes a division of the space in case 20 and also for this reason is called partition frame or baffle. Although the provision of the support frame 21 in case 20 is advantageous, the support frame 21 may be omitted in an alternative embodiment. From now on, however without any limitation, reference will be made to the case in which the changeover switch 100, and case 20 in particular, comprises the support frame 21. Thus, when it is described that certain components of the changeover switch 100 are fastened to the support frame 21, this is to be understood in the sense that such components may be directly fastened to case 20, if the support frame 21 is not provided.

  • the changeover switch 100 proposed allows the preset objects to be completely achieved in terms of overcoming the drawbacks of the switches of the known art. Indeed, a significant reduction of the axial volume was obtained due to fact that the rocking switching member 60 rests on the support fulcrum 90 with an end portion thereof because the rotation angle of such a member may be kept more limited with respect to the known art while successfully ensuring the provision of three stable angular positions of such a rocking member 60.
  • the two side buttons 30a, 30b may be moved independently from each other, they may always be kept perfectly aligned, whatever the stable angular position taken on by the rocking switching member 60. Moreover, the inertias are reduced during the movement of the side buttons 30a, 30b.
  • the presence of the central button 30c allows the rocking switching member 60 to accurately take on the stable central angular position.
  • a changeover switch 100 of the above-described type may be for example, however without any limitation, used in hotels for controlling a signaling device aiming to inform the hotel service personnel of a do not disturb request and a please make up my room request.
  • Pressing the side button 30a may be carried out for example to signal a do not disturb request.
  • Successively pressing the central button 30c brings the changeover switch 100 to a neutral position, which practically resets the aforesaid signaling.
  • the central button 30c may be made so that it may transmit an optical radiation therein, for example by making it of clear material.
