-Fixed submission scale to the correct mm rather than inches
-Basically the same as my other entry with polish and stack-up fixes.

"The winning electromechanical pressure switch design will accomplish the following:
- Diaphragm activated momentary switch, normally open and normally closed options." Y
- Design enables efficient automation process and eliminate manual assembly with minimal changeover to alternate configurations. Y
- Differential, vacuum and positive pressure options. Y
- Electrical Connection options: Both male quick connect (4,7 X 0,5 mm) and Pin configurations Y
- Automated calibration enabled to adjust pressure set point at testing. Y
- Ports interface for 8mm flexible tubing diameter maximum. Y
- Pressure ranges: 15 to 40 Pa (low) and 30 to 160 Pa (high). Theoretically Y
- Maximum body size envelope: 25 X 25 X 7mm.
- Preferred body size envelope: 14 X 14 X 7mm. Main body is within 14x14x7 mm volume. All other parts withing 25x25x7mm minus 8mm air nozzle violates 7mm limit but only because it was specified in requirements. Nozzle can be shrunk to any dimension or replaced

- Highlights core manufacturing technologies (injection molding, stamping, assembly, tooling, machining, insert molding, and automation). With a bonus of heat-staking.
- Utilizes accelerating manufacturing technologies and materials. Y
- Cost effective design with least amount of materials. Y

Development of a diaphragm operated vacuum/pressure micro-switch.
Switch allows setting sensitivity and normally open or closed operation for either vacuum or pressure via adjustment screws.

Diaphragm is made of "Metal Rubber" elastomer that has been doped to be conductive. (https://en.wikipedia.org/wiki/Metal_rubber) Which can have a resistance a low as 1/10 of an ohm. The common quick connect makes direct contact with the rim of this diaphragm.

Reduced parts count to 6 unique components (8 physical) two of which are screws down from 13 shown in drawing. Eliminated rivets in favor of heat stake fastening all components including what i assume is a % glass-fill body.

End notes:
Weight of product is not possible as I don't have the density of the materials that Microtechnologies Inc. has decided on.
Model still needs draft and radii put in before molding, these also effect weight. I left these out because they are much easier to add than to take out when model tweaks are desired.

Screws and air nozzle are mainly place holders and should be replaced with what Microtechnologies Inc. uses commonly.

Diaphragm thickness will need adjusted once better data is available on elastic properties of "Metal Rubber".

Switch would fit well into some sort of snap mount cradle. Plug everything into place air etc then snap switch in place.
