ABSTRACT:
An electrical device consisting of a package 10 comprising a base 11 and a lid 15 and an operation element 17 contained within the package. A particle getter 19 is disposed on the lid 15 for entrapping and retaining foreign particles contained within the package 10. A method for protecting the operational element 17 of such an electrical device from the particles is disclosed wherein a polysiloxane material is partially cured with less than about 9 parts of a suitable curing agent to 100 parts of polysiloxane resin to a non-flowing, particle entrapping and retaining condition and the partially cured material is secured within the package.
