Abstract
The present invention relates generally to methods and apparatus for the manufacture of binary switches for use in the medical monitoring field and membrane switches for use in a variety of contexts. More particularly, the instant invention involves the construction, manufacture, and operation of pressure sensitive patient sensors of the sort commonly used in medical settings which can be used, for example, to detect when a patient has exited a chair or a bed. The instant application additionally teaches the construction of membrane switches for use in, for example, electronic instrument control panels. Both the binary switches and membrane switches taught herein are preferably formed from alternating layers of polyester and polyethylene.
