Hi there I would like to buy a button for a project I am working on.

The button I have in mind is a momentary button housed inside a 3 or 4 inch long by 3/4 inch cylinder, with the button at the top and the wires comming out the bottom.

I believe I have seen a similar button in movies where the user is holding down the normally red button as some sort of dead man switch.

This is not my intention. Infact it is quite the opposite. Last year my father passed away after suffering a broken back above his diaphragm, because it was above the diaphragm he was unable to cough and clear his lungs. Sadly the only solution to this problem was a breathing tube and the subsequent binding of his arms to prevent the removal of the tube. As a result he was not able to communicate with us or the nurses. I believe his inability to communicate was the cause of him falling into a psychosis that eventually caused his passing.

I would like this button to use as part of a system I am building that will make use of Assistive Context-Aware Toolkit (ACAT) made by Intel and used by Stephen Hawkins.

I am aware that the environment supports cameras and there are other more useful buttons but my knowledge and finances are limited and I just want to make a very simple tool that will help the next poor soul that finds themselves in a similar situation to my Dad's.

Thanks.
