ARRANGEMENT OF PUSHBUTTON SWITCHES WITH A PROGRAMMABLE DISPLAY

Description

Field of the art

[0001] The present invention relates to an arrangement of pushbutton switches with a programmable display, in particular a display with OLED (short for "organic light-emitting diode") diodes included in the push-button head and supported on a push-button actuator member having limited linear shift play inside an enclosure body that has an affixed micro switch, which is activated by said linear shift when the push-button is operated.

[0002] The invention provides, to that effect, a support structure of a plurality of pushbutton switches that are coupled to a printed circuit board forming a functional arrangement, so that any of the pushbutton switches of the arrangement may be easily replaced without the need of handling connection cables.

[0003] Each of the pushbutton switches further comprises an enclosure body made of a light-conducting material that is associated in said support structure to lighting LED diodes so as to provide lighting to a frame of said enclosure body. Said LED diodes may in turn be connected via said printed circuit board to a control unit for their dynamic activation, generating movement effects in the luminous aureole provided.

State of the prior art

[0004] Switching devices that include a display in their head are known from documents EP-A1-1347363 and EP-A1-1589551.

[0005] Patent applications EP-A1- 2110833 and EP-A1- 2211361 describe such pushbutton switches with and OLED display.

[0006] US-B1-8410383 describes, as prior art, a plurality of pushbutton switches grouped together in a unit via a support structure according to the general characteristics defined in the preamble of claim 1, i.e. formed by an assembly panel, a printed circuit board and a shielding plate fixed to one another in a sandwich arrangement, but where each pushbutton switch is coupled to the support structure through auxiliary boards and support frames attached to the printed circuit board, so that when there is a need of removing one of the pushbutton switches, for example in order to substitute it because of malfunctioning, such a substitution task is a very laborious task, because in order to carry it out it is necessary, first, uncoupling the whole support structure so that the assembly panel can be removed and, then, individually uncoupling the damaged pushbutton switch from its respective support frame.

[0007] In connection with the latter background art, the invention proposes a support structure and integration means of a plurality of push-buttons in an assisting and/or connecting printed circuit board (it may include local control units) that involve a remarkable simplification with respect to said background art and an improvement of the capabilities, especially with respect to the mentioned substitution of a damaged pushbutton switch, being possible to perform such a task in a simple manner without having to uncouple the whole support structure but only individually the pushbutton switch.

[0008] Document US 2008073190 A1 discloses a push button switch for use in an amusement or gaming machine and an arrangement of such push button switches. The push button switch includes an enclosure body to which a micro switch is affixed, an actuator member having limited linear shift play inside the enclosure body, the micro switch being activated by said linear shift when the push button is operated, and a lamp or a programmable display attached to the enclosure body for illuminating the actuator member. The micro switch and the lamp or programmable display are fixed to terminals projecting from the enclosure body. The enclosure body has a bezel and immobilizing means. The arrangement of push button switches includes an assembly panel having a plurality of openings for arranging therethrough the enclosure body of each push button switch, and a printed circuit board including control elements for controlling the micro switch and the lamp or programmable display of each push button switch and connection elements to which the terminals of each push button switch are connected. The enclosure body of each push button switch is attached to the assembly panel by the immobilizing means and with the bezel supported on the assembly panel.

[0009] According to what has been set forth above, the invention is intended for grouping an arrangement of pushbutton switches with a programmable display in an operating unit or block, each of which comprises a display, visible from outside, installed in an actuator member of the push-button that exhibits limited linear shift play inside an enclosure body that has an affixed micro switch, which is activated by said linear shift when the push-button is operated. Said display is covered by a lens and by a transparent cover.

[0010] In order to group a plurality of pushbutton switches with a display and even other standard pushbutton switches, a support structure has been provided comprising:

• an assembly panel with a plurality of openings for arranging there through the enclosure body of each pushbutton switch of the arrangement, with the support of a bezel on the sides of said opening, on said panel;

• a shielding plate of said printed circuit board; and
• separating or spacing columns and attachment means linking said panel, printed circuit board and plate in an overlapping arrangement.

[0011] According to the proposal of this invention, the enclosure body of each pushbutton switch comprises, in turn:

• an appendix intended to be arranged through through-openings defined in said panel, printed circuit board and plate, said through-openings facing each other (for example being vertically aligned) in said support structure; and

[0012] the enclosure body includes, attached or integrated thereto, a first insertion connector that is opposite to and engaged with, in an assembled situation, a second connector provided and arranged in said printed circuit board for connecting the corresponding display and the micro switch.

[0013] In addition, removable immobilizing means of said appendix with respect to said shielding plate have been provided, through which each enclosure body is attached to said support structure. According to a preferred embodiment, said immobilizing means comprise a nut with a coupling configuration to be coupled to said tubular shaft by a respective complementary coupling configuration integrated with or attached to the tubular shaft, so that said nut is tight against said shielding plate, suitably securing the pushbutton switch. Said coupling configurations are, for a preferred embodiment, bayonet coupling configurations, although, for other embodiments, less preferred, other kind of coupling configurations are possible, such as those formed by complementary screw threads.

[0014] The printed circuit board includes one or several LEDs that, in an assembled situation, are close to walls of said enclosure body of each of the pushbutton switches, said enclosure being made of a light-conducting material so that the lighting of said LEDs is transferred through the enclosure body to said bezel above the panel.
