Definitions

  • the present invention relates to the field of unipolar or bipolar electrical switches, of various kinds and various sizes, and which are used in electrical and electronic apparatus, as well as in household appliances. More specifically the invention relates to switches intended to operate in environments of high humidity and/or in the presence of liquid.
  • the purpose of the present invention is to furnish an electrical switch protected against dust, humidity, and water spraying with means of protection integrated into the switch unit, more precisely, molded along with the unit properly speaking.
  • this switch unit has the advantages of not having to produce and install separate elements; of reducing the production costs; of having free choice in the shapes and in the appearance of the manufactured product; of guaranteeing a degree of tightness and protection comparable, if not even better, than that achieved by the more customary elements with respect to the current standards.
  • a switch unit mounted in a panel, where the switch includes a first or front part with a perimeter flange positionable adjacent the panel and an inner piece defining a central opening.
  • a control element movably mounted on the first part between a first and second position.
  • the control element includes a stem extending into the central opening.
  • a second part is connected to the first part, and the second part includes a plurality of fixed electrical contacts.
  • a mobile contact is connected to the stem of the control element, and the mobile contact element electrically connects and disconnects two or more of the fixed electrical contacts depending on a position of the control element.
  • a panel seal means is positioned on the perimeter flange of the first part and seals a junction between the first part and the panel.
  • the panel seal means includes a soft flexible material molded with the first part.
  • a stern seal means is connected to the first part at the central opening. The stem seal means surrounds the stem of the control means and seals a junction between the inner piece and the stem.
  • the switch illustrated comprises a unit 11 of the type comprised of a front part 12 and a rear part 13.
  • the front part 12 is of rigid material and presents a front peripheral flange 12' and an inner piece 12" converging to a center, where it defines an opening.
  • the rear part 13 of the unit also rigid, has a bottom wall 13' bearing fixed contacts 14 for at least one electrical circuit and presents two clamping tabs 13" at the two opposite sides.
  • the front part 12 of the switch unit bears a control key 15, swiveling on an axis defined by pins 15' housed in sockets produced in the sides of the part, as shown in Fig. 2.
  • the key has a stem 15", rigid or with an elastic part, which fits in the opening defined by the inner piece 12" and which extends as far as a mobile contact 16, pivoting on a fulcrum 16'.
  • the mobile contact is controlled by the key to open and close the circuit(s) which lead to fixed contacts 14.
  • the inner face of the front perimeter flange 12' has a seal 17 made of soft material molded along with the front part of the unit.
  • the seal has a suitable shape to guarantee exclusion of dust and moisture between the front flange 12' and a panel 18 to which the switch is fastened for its use.
  • This seal 19 is obtained by co-molding on the inner piece 12" opposite the opening defined by it.
  • the seal 19 adheres to the stem 15" of the key without influencing its movements, but rendering inaccessible the inner chamber which is created between the front and rear parts of the unit and protecting the mobile and fixed contacts.
  • seals 17 and 19 obtained by molding along with the front part of the switch unit offer good protection against ingress of dust and water from the outside, when the switch is in operation, without adding any other element.
