Designing a diaphragm for a low pressure air switch.

I need a diaphragm for a low pressure switch. The diaphragm must be electrically conductive, between 5-10mm diameter, which deflects/distorts when subject to an air pressure of 1kPa. Please see attached sketch. The degree of distortion is not particularly important as the distance between the contact and the diaphragm is adjustable. The diaphragm must be able to withstand pressures of 10kPa without breaking. It will be used at room temperature and will only be exposed to normal air. It will be a differential pressure switch. The diaphragm must be quick to respond (<[url removed, login to view]) to both an increase of pressure >1kPa and a drop <1kPa. I have already experimented with some conductive silicone but it was too slow to respond and unpredictable. I think a metal diaphragm would be better. Hopefully you will be able to manufacture the diaphragm, but if not I will need to be able to take the design to a manufacturer for production.
