No fitting Switch available
« on: September 24, 2012, 03:54:13 PM »
Hi

In Kuopio we decided, that the puzzlepieces will be fixed with the switches. The only problem is, that no switch has a screw as long as we need it (10mm plate + cover + desk + nut = min. 20mm).
But I think, fixing the plates is not necessary. The box has to have little angels at the side, that the plates cannot slide away, that's all. During transportation they are fixed by the foam. If you cannot imagine, I can add a little drawing of my intention. In this way I can choose a cheap switch, that looks good.

Who (which country/school) is producing the box?

kind regards
Friedrich

Hi Friedrich,
I think that Swedan (Mattias) is producing the box. Send him an e-mail. It will be tha fastest way to arrange that

Hi Friedrich/Goga

Yes Mattias is making the Desk.
But puzzle piece = 10mm + cover = 2mm + desk = 2.5mm (Total = 14.5 say 15mm)
Maplin do a switch with an 18mm thread (see attached)

I think one thing he needs to know is the depth of the box.
It looks a bit deep. Does it have to hold a battery or transformer? What size?
The thinner the better I think.

Regards
John

Hi

@John:
Sorry, too late. The switches are already ordered and delivered.
We (the students and me) also don't think, it is not a good idea, to use switches with a square shape. It will not look good, when even not all of them are in a correct position. It will be more easy for us (-> KISS) to use a round one. The one, that Maplin will offer, has a price of 7,50, that is to much. This ones we have now: Conrad. It is a round one and the price is half of Maplin.

@Mattias
500x500 will fit. Maybe you can make something like angles, two sides a little fexible, so we can jam the whole puzzle. I think, this will be enough of fixing. Please also think about the holes for the cables. I think, a diameter 12mm will be enough. The positions of the holes you can take from the drawings of the puzzlepiece, where our boys have shown the position and dimensions of the slot, the switch and the engraving. Here you have the pdf-File. The ACAD-File is somewhere here in this forum.

@all
The cover is cellular rubber in black and 3mm thick. I have got it from a company in Vienna for free! It looks very good and the pieces will not slide until an angle of ~35.

Let the sun shine
Friedrich

Hello Friedrich,

the control group needs to know the type of switches you have ordered.  ???
In particular they need to know if the switches are normally open or normally closed. In other words, if the lamp turn on when the button is pushed then the switch is normally open, otherwise if the lamp turn off when the button is pushed then the switch is normally closed.

We are waiting for an answer asap.

King regards

Michele

Hi Michele

The switches (correct: I think the english word is pushbuttons) are NO (normally open).
