Definitions

  • the present invention relates to a two-pole integrated switch.
  • Two-pole integrated switches to be used typically in electrical household appliances are known and widely used.
  • Such integrated switches are normally constituted by a base or socket with which a fixed connector block is associated; in the case of two-pole switches, such block is constituted by two pairs of fixed contacts.
  • Such pairs of fixed contacts can be mutually connected by moving a respective moving contact which can be actuated by a control button.
  • Switches of this type have, depending on their template defined on the appliance for which they are intended and within which they are to be associated, sockets having different shapes and dimensions.
  • circular sockets with a diameter of 25 mm in which the two pairs of fixed connectors are angularly spaced along circular arcs formed at the edge of the socket, or rectangular sockets which have a length of 19 mm and a width of 13 mm are used.
  • the two pairs of fixed connectors face each other and are side by side along the longer sides (the 19-mm sides) of the socket.
  • the aim of the present invention is to provide a two-pole integrated switch which has a socket whose dimensions are smaller than those of currently available switches.
  • an object of the invention is to provide a two-pole integrated switch which is capable of bearing currents whose intensity is substantially equal to 16 amps but can be associated with extremely small-diameter circular templates.
  • Another object of the invention is to provide a two-pole integrated switch which has an extremely simple structure, so as to allow quick and easy assembly of its components.
  • Still another object of the present invention is to provide a two-pole integrated switch which has a competitive production cost, so that its use is advantageous also from an economical standpoint.
  • an integrated two-pole switch which is provided with a socket which supports two pairs of fixed contacts and is associated with a containment body for a movable connection device actuated by an actuation button, characterized in that the perimetric portion of said socket has two elongated portions which are substantially straight and mutually parallel and are associated with said two pairs of fixed contacts and are mutually connected by means of two connecting portions, at least one of said two connecting portions comprising a blending portion which has a substantially convex outward shape.
  • a two-pole integrated switch generally designated by the reference numeral 1, comprises a socket or base 2, which supports a fixed connector block 3 provided with two pairs of fixed contacts 4a, 4b and 5a, 5b.
  • the socket 2 is associated with a containment body 6, inside which there is a movable connection device of a per se known type, which can be actuated by an actuation button 7.
  • a pair of moving contacts is moved which constitutes the movable connection device and is designed to open/close the electrical contact between the two pairs of fixed contacts 4a, 4b and 5a, 5b.
  • the socket 2 has a perimetric portion 2a, which comprises two elongated portions 8a and 8b, which are substantially straight and mutually substantially parallel.
  • the two elongated portions 8a and 8b are associated with the two pairs of fixed contacts 4a, 4b and 5a, 5b so that, as also shown in the figures described above, the fixed contacts of the same pair are arranged in front of each other at a respective elongated portion 8a, 8b.
  • the pairs of respective fixed contacts 4a, 5a and 4b, 5b are mutually side-by-side.
  • the two elongated portions 8a, 8b are mutually connected by means of two connecting portions 9a, 9b.
  • At least one of the two connecting portions 9a, 9b comprises a blending portion 10, which is substantially convex outwardly.
  • At least one and preferably both connecting portions 9a, 9b to have a respective blending portion 10 which is substantially convex outwardly.
  • the blending portion or portions 10 comprises or comprise an intermediate portion 10a, which is substantially straight and runs along a direction which is substantially perpendicular to the main longitudinal direction of the two elongated portions 8a and 8b.
  • Two end portions 10b lie between the intermediate portion or portions 10a and the respective elongated portions 8a and 8b, are arranged on opposite sides with respect to the respective intermediate portion 10a, and are substantially inclined with respect to the intermediate portion 10a and the respective elongated portion 8a or 8b to which they are connected.
  • the end portions 10b comprise a curved portion which has a convex outward shape: conveniently, the center of curvature of said curved portions is located at the center of the socket 2.
  • a socket 2 which has a footprint ranging from 19 to 22 mm, preferably from 19.5 to 20.5 mm, so that it is possible to insert, as clearly shown in the sequence of Figures 1 to 3, said switch 1 in a template 11 which has a circular shape and a diameter of substantially 20 mm.
  • the two-pole integrated switch described above allows to reduce space occupation considerably.
  • the materials used, as well as the contingent shapes and dimensions may be any according to requirements.
