Dash Switches.
Discussion
Im in the process of having a new dash designed and cut from stainless steel.(again)
I was initially going to have 'c' shapes cut in the steel which would be flexible enough to bend when pushed, allowing them to touch a pressure switch behind, giving a smooth finish to front of dash.
This is proving hard as i cant find suitable pressure switches for the back..
So i have thought of using Piezo switches, which will give a touch screen style feel to the dash.
Has anyone on here used this style of switch or do you have any thoughts ?

Never seen them in the flesh but just had a browse on there website and they certainly look up to the job. For anyone else thats interested inthe specs http://www.piezoswitch.com/about_switches.html
Do you know if they will fit in without having to modify much?...What would be nice would be a dash with the warning light images cut out. Then you could get rid of bracket that holds the whole row of switches and warning lights...replace the switches with piezo ones in just the whole in dash and then make something to hold the leds for warning lights which would be easy with some of the small leds you can get hold of today.
Like these ones
G series
and these the F series

I have changed the dash already to a carbon one, so i have got lights and switches fitted.
I wanted a touch only style dash to try to make it a little modern in look.
With the piezo switch i think i will have to get relays on each switch, then something to convert the one press to a prolonged action, like the on off light buttons.
The press on, release off is ok for central locking and boot but will need adapting for the lights.
At present the removal of the light brackets at the back have not caused any problems with connections, but im worried about shorting the power if i have an alloy only dash..any ideas on how to avoid shorting every time i go over a bump ?

Hi there
I replaced my switches with momentary switches i.e the contacts are only closed whilst the switch is pushed.
I then needed to build a latching circuit that held a relay closed until the button was pressed again.
Had to build one latching circuit for each switch - side lights, main lights, fogs, hazards, fan overide.
Put all the circuits onto one board mounted in a box behind the dash.
Also wired in some toggle swiches for the lights as a backup in case the elctronics failed
I should imagine that piezo switches will need a similar setup
Give me a shout if you want any more info
Cheers Andy

Thanks for that, can you give me an idea of the circuit diagram you have worked with please..I replaced my switches with momentary switches i.e the contacts are only closed whilst the switch is pushed.
