How to 'disable' button
speedyxjs - 23/10/09 at 10:29 AM

Reading rgrs's post in this thread (p2), i was wondering how to disable the button so it might magically, re-able itself post IVA?

Make an ali cube, just so that it fits over, use a weak glue, so you can pull it off post test?

can you mount it behind the dash so the buttons are covered?

No. Iv already made the dash and dont really want to make another one. I like the ali cube though. Would it be seen as perminant?

well, I suppose that would depend on the glue you used. And its sort of 50/50 wether the tester will give it a tug...?

Can you get inside the casing? If so, you might be able to slip a bit of thin plastic into the switch to deactivate it temporarily - the tester can push it as much as he likes but nothing would happen.

Alternatively, can you make something that fits behind the unit (ali or stainless sheet) that curves under the base and stops the button being pushed? If you put a bit of effort into it you can make it look 'permanent'.

I had the same issue with my veypor VR2. I made an ali plate so it covered the buttons and some vinyl covering it.
Can't have been fixed properly because it and the steering pad it was sunk into came off very quickly after sva. Pretty strange realy

In the past I've disabled similar buttons (like the ones on telephones) by slipping thin bits of plastic between the buttons and the contacts on the PCB behind them. Works for the type of button where the back of the rubber / plastic bit has a bridging contact on and the PCB bit is just two metal contacts... Would mean opening up the speedo but hey...

From the title of this thread I thought you were proposing to nobble the F1 World Champion

Unfortunately the design of the button prevents you from physically placing something in the switch path.

The rubber buttons cover a long shaft switch.

On mine i opened the unit and cut the track on the pcb to disable the button for my re-test.

Somehow shortly after sva a small blob of solder fell into the unit and re-joined the track..

However this would ovbiously invalidate any warantee.
