Definitions

  • the present invention relates to a display system for operating positions of an electrical switch.
  • An industrial or household electrical appliance such as a washing machine, a dishwasher usually comprises one or more operating control switches.
  • a visualization of the position of engagement or tripping of this or these switches facilitates a check of correct operation of the device and contributes to ensuring safety in the use of it.
  • the known systems for displaying the operating positions of electrical switches are often indication systems such as On-Off, systems with a light signaling device or systems with a colored signal element.
  • the aim of the present invention is to avoid these drawbacks, which makes it possible to produce an economical system for displaying the operating positions of an electrical switch, which has a simple, solid structure, formed of component parts which are easy to manufacture and to assemble without independent mechanical means fixing or holding.
  • a system for displaying the operating position of one or more associated electrical switches is characterized in that it comprises at least one support, an operating lever, and a descriptive element constituted by interlocking parts by interlinking. mechanical.
  • the invention is applicable to position display systems of one or more associated electrical switches of a known type with push-button with locking engagement fitted to industrial or household electrical appliances such as washing machines, dishwashers, etc.
  • the electrical switches of the known type with push-button with locking engagement 1 schematically and partially shown in FIGS. 3, 4, 5, 6, 7 are switches usually having a control axis of the push-button type 2.
  • their engagement is obtained by axially pushing their axis 2 from its rest position inwardly of these switches to its engagement position where it is mechanically retained in place.
  • their axis 2 is pushed axially towards the inside of these switches beyond its engagement position to cause its release and its automatic return to its initial rest position towards the outside of these switches, by a known device with return spring.
  • a system for displaying the operating positions of one or more associated electrical switches of the push-button type with locking engagement comprises at least one support, an operating lever and a descriptive element constituted by interlocking parts by interlinking. mechanical, in other words, maintaining their assembly does not require independent mechanical fixing means.
