Definitions

  • the present invention relates to electric switches and, more particularly, a switch of the type in which the switching occurs as the effect of the displacement of a rocker arm between two stable positions.
  • the object of the invention is to propose a switch of the rocker-arm type, but operated by a push-button.
  • connection terminals 21.1, 21.2 Two of the three connection terminals, 21.1, 21.2, are connected, in the present example as integral portions, to respective sheet-metal tags 24.1, 24.2 situated within the structure 16 below the base wall 11. Each tag is provided at one of its ends with a fixed electric - contact, respectively 3.1, 3.2, that can be accessed from inside the supporting structure 2 by means of a rectangular opening 25 provided in the wall 11.
  • the third connection terminal 21.3 is connected, in the present example as an integral portion, to an L-shaped sheet-metal bar 27 arranged in the structure 16 at right angles to the longer side of the base wall 11 in such a way that its edge 26 emerges from the opening 25 in a central position with respect to the fixed electrical contacts 3.1, 3,2.
  • a control element 47 is formed by a small block 6 made of insulating material and a spring-controlled pin 7.
  • the small block 6 is mounted inside the supporting structure 2 in such a way as to be capable of pivoting around an axis a2 parallel to the axis of rotation of the jumper element 4. More particularly, on the walls 12, 13 there are situated two opposite holes 33 that accommodate two opposite prominences 32 on the block 6 of the control element 47.
  • the pin 7 has a rounded tip and is pushed by a spring (not visible in the figure) that is compressed in a cavity of the block 6 to constitute an elastic connection between the block 6 and the metallic jumper element 4 below it.
  • the upper part of the block 6 is designed in such a way as to have a cavity with surfaces 36 that are shaped substantially as steps and are symmetrical with respect to a plane containing the axis of rotation a2.
  • the supporting structure 2 is closed at the top by an operating organ 46 that is connected to the control element 47 and comprises a push-button 42 made of insulating material.
  • the push-button 42 consists of a rectangular plate 9 and four coupling elements 45 that are integral with the plate.
  • the elements 45 are formed by elastic tongues 40 projecting at right angles from the plate 9 near the ends of its larger sides and guide teeth 41 projecting from the ends of the tongues.
  • the operating organ 46 also comprises a pressure-transmission means 8, which has two ends 44 and a flat surface that faces the lower surface of the plate and is fixed below the plate 9 in such a way as to be capable of pivoting around a third axis a3 parallel to the two axes a1 and a2.
  • the switch 1 is a modular electrical device having the function of a two-way switch, utilizable, for example, for switching the lines of domestic installations.
  • the device is fixed to a supporting frame (not shown), usually with joint-type couplings.
  • prominences 17 are provided on the walls 14, 15 of the container 2 and are shaped in such a way as to fit into complementary rebates of the frame.
  • the push-button 42 Prior to every switching of the switch, the push-button 42 is in its rest position at a certain distance from the supporting structure.
  • the pressure-transmission means 8 is likewise in its rest position, its plane of symmetry coinciding with the plane, indicated by the reference number 28, containing the axes of rotation a1, a2 and a3, due to the elastic action of the foil spring 22, which, in this particular embodiment of the invention, integral with the foil spring 10.
  • the block 6 of the control element 47 and the jumper element 4 are inclined in one of their two stable angular positions. For example, as shown in Figure 3a, when the block 6 is inclined towards the left, the jumper element 4 is inclined towards the right and the mobile contact 5.1 is pressed against the fixed contact 3.1.
  • the transverse thrust causes the block 6 to rotate even further in the clockwise direction around its axis of rotation a2, until it eventually snaps it into its second stable position ( Figure 3d) in which it is inclined towards the right.
  • the pin 7 slides on the jumper element 4 from one end of the rounded profile to the other, causing the jumper element to rotate about its axis a1, that is to say, around the edge 26 of the L-shaped bar 27, until it eventually snaps it into its left-hand stable position, in which the mobile contact 5.2 is pressed against the fixed contact 3.2.
  • the spring 10 brings the push-button 42 elastically back into its rest position, the pressure-transmission means 8 reacquires its rest position, while the block 6 and the jumper element 4 remain in the new positions they have assumed.
  • the elastic element that maintains the pressure-transmission means 8 in position is constituted by two counterposed lamellae 22' that are symmetrical with respect to the plane of symmetry 28 and form an integral part of a structural element of the push button 46.
  • the elastic element is constituted by two counterposed foils forming an integral part of the pressure-transmission means 8 that rest with their ends against the internal surface of the push-button 46.
  • the switch described herein can be employed both as a one-way switch and as a diverter switch, i.e. as a two-way switch, and, with the sole addition of an elastic means, like the spring 50, that keeps a mobile contact (5.1) and a fixed contact (3.1) apart from each other, also as a traditional push-button.
