Description
- The present invention relates to electric switches, and more particularly, switches of a type in which the switching is carried out due to a pivoting switching member which moves between two stable positions.
- By "switch" is meant herein both a device that opens and closes a single contact and a device that opens one contact and simultaneously closes another contact, and vice versa (diverter switch).
- Several types of switches of the above kind belong to the prior art, generally including: at least two connection terminals, at least one fixed electric contact being electrically connected to one of the two connection terminals and a switching member, which is provided at one end thereof with at least one mobile electric contact and resting on a fulcrum or support that is electrically connected to the other of the two connection terminals. These switches further include an operating mechanism to be manoeuvred by means of an axial push-button, or lever, or rocker key for moving the switching member such that the latter rotates to reach either one of its two stable positions.
- A switch as discussed above and push-button operated is described for example in the International Patent Application
WO 2006/106554 . - By means of tests that have been carried out using a high-speed video camera, it has been possible to observe how, in the above prior art switches, the pivoting switching member, during the switching process, can be lifted from the fulcrum on which it is rested despite being held thereto by suitable resilient means.
- This disconnection, even though limited to a few split seconds, can impair the good operation of the switch. In fact, during this disconnections, electric micro-arcs are formed that cause local corrosions or fusions which can, in turn, cause overheating or power failure.
- The object of the present invention is to provide an electric switch which free of the drawbacks cited above with reference to prior art switches, or which is affected by these drawbacks in a very reduced manner as compared with prior art switches.
- This object is achieved by means of a switch as generally defined in

pin 29 has a rounded tip and is biased by a spring (not seen in the figures) that is compressed in a cavity of theblock 28 in order to provide an elastic connection between theblock 28 and theunderlying pivoting jumper 16, when thecontrol mechanism 20 is fixed to the supporting structure 2. Theblock 28 is shaped on top such as to have acavity 32 with substantially step-shaped surfaces. - The
control mechanism 20 further comprises a pressure transmission means 33, illustrated in phantom inFig. 1 , which has two substantiallypointed ends button 21 below thekey 23 in a pivoting manner about a third axis substantially perpendicular to the sheet plane. - Two

element 14 includes aforward region 15 which acts as a rest point and fulcrum for the switchingmember 16, and includes abackward region 31 that acts as the rest point for the laminarelastic element 30. - It should be observed that, in the particular example as illustrated in the figures, the supporting
element 15 is a metallic bar having theforward region 15 thereof substantially cusp-shaped and having thebackward region 31 that is a recess or notch of thebar 14. It should be further observed that, by providing the width of themiddle portion 17 of thepivoting jumper 16 to be of a greater size than the width of therecess 31, thepivoting jumper 16 is thus rested on twoparts 15 of thebar 14, which are counter-posed relative to therecess 31. Furthermore, by providing the width of the middle portion 34 of the laminarelastic element 30 to be lower than the width of therecess 31, the middle portion 34 of the laminarelastic element 30 is received within therecess 31. - In a particularly preferred embodiment, the middle region 34 of the laminar
