Definitions

  • the present invention relates to a switch.
  • switches used in electrical devices are often constituted by a box-like body which has a base, or shoe, which is associated with at least one connector which supports, at its respective ends, two moving contacts; the base is further associated with a respective pair of fixed contacts.
  • rocking of the key causes, due to the interposition of kinematic connection means between the key and the connector (or connectors), oscillation of the connector, with the result of ensuring selective contact of one of its moving contacts with a respective fixed contact.
  • some of these switches have kinematic connection means constituted by a fork for accommodating a respective spring designed to engage an engagement pin, which protrudes from the connector at its oscillation axis.
  • the aim of the present invention is to eliminate or at least reduce drastically the drawback noted above in the types of switches described above.
  • an object of the present invention is to provide a switch that has a very simple structure, so that it is advantageous also from an economical standpoint.
  • Another object of the invention is to provide a switch which can be used also as a button.
  • a switch comprising a box-like body which has a lateral containment portion and an intermediate closure element which has a through opening and forms, with said lateral containment portion, an upper or actuation portion and a lower or containment portion, said box-like body being associable, at said lower portion, with a shoe which supports at least two fixed contacts and at least one connector, which is mounted so that it can move between a first stable condition and a second stable condition and is functionally connected to an actuation element provided with a respective spring element, which is accommodated within a containment recess, and is functionally connected to said connector and has, on the opposite side with respect to said containment recess, an abutment body which is accommodated substantially at said through opening, means being provided for forming a seal between said abutment body and said intermediate closure element, said abutment body having a receptacle for a pin supported by a key, characterized
  • a switch generally designated by the reference numeral 1, is provided with a box-like body 2, which comprises a lateral containment portion 3 and an intermediate closure element 4.
  • the intermediate closure element 4 is provided with a through opening 5 and forms, with the lateral containment portion 3, an upper or actuation portion 6 and a lower or containment portion 7.
  • the first stable condition can be associated with an active or functional condition, in which the moving connector closes an electrical contact in order to supply current to an electrical device, while the second stable condition can be associated with an inactive condition, in which therefore the electrical contact is open.
  • first and second stable conditions prevents the first and second stable conditions from being associated with two active conditions, so as to allow to supply a first electrical device in the first stable condition and a second electrical device in the second active condition.
  • the connector 11 is functionally connected to an actuation element 12, which is provided with a respective spring element 13 accommodated within a containment recess 14 provided on the actuation element 12.
  • the actuation element 12 has, on the opposite side with respect to the containment recess 14, an abutment body 15, which during use is arranged substantially at the through opening 5.
  • sealing means which comprise a sealing element 100, which protrudes from the edge of the through opening 5 and is elastically deformable in order to press against the abutment body 15.
  • the abutment body 15 has a receptacle 17 for a pin 18 supported by a key 19.
  • the key 19 is articulated to the box-like body 2 by means of two rotation pivots 101, which are supported by the key 19 and are designed to be moved to engage a respective rotation seat 102 provided at the lateral containment portion 3 of the box-like body 2.
  • both the rotation pivots 101 and the respective rotation seats 102 are arranged at the oscillation axis of the key 19.
  • the abutment body 15 can be substantially shaped like a spherical dome, so that the sealing element 100 can be substantially annular.
  • the sealing element 100 is provided monolithically with the intermediate closure element 4.
  • the intermediate closure element 4 may have at least one abutment element 22 for a spring 30, which is designed to act by pushing against a pusher portion 23 supported by the key 19, so as to be able to use the same switch structure 1 also as a button.
  • the spring element 13 is functionally connected by resting against an actuation protrusion 26, which protrudes from the connector 11 toward the intermediate closure element 4.
  • the shoe 8 supports at least one pair of fixed end contacts 10a and at least one intermediate contact 10b.
  • the connector 11, in this case, is constituted by a lamina which is mounted so that it can oscillate with respect to the intermediate contact 10b and has, at its longitudinal ends, two contact pads 25, which as a consequence of the rotation of said lamina, are designed to connect selectively a respective fixed end contact 10a.
  • the shoe 8 can be constituted by a lateral element 8a, which is designed to face a lower portion of the lateral containment portion 3, and by a lower frame 8b, which is designed to rest against the lower edge 3a of the lateral containment portion 3.
  • the lateral containment portion 3 may have, at the upper or actuation portion 6, at least one discharge opening 40.
  • Such discharge openings 40 allow to evacuate any liquids or dust from the upper or actuation portion 6, so as to ensure correct mobility of the key 19.
  • said switch allows to protect simply and effectively the contacts against dust or water.
  • the switch is to be used as a button, it is sufficient to insert a spring.
  • the materials used, as well as the contingent shapes and dimensions may be any according to requirements.
