ABSTRACT:
A sealing device and method are disclosed for use in connection with a switch mounted upon a panel by a panel nut engaged with a threaded bushing projecting from the panel. A boot member of a resiliently flexible elastomeric material is placed over the switch and is secured by a mounting nut to the threaded bushing to establish a seal. An annular bearing member is interposed between the terminal end of the threaded bushing and a juxtaposed portion of the boot member so as to protect the juxtaposed portion from damage that might otherwise occur as a result of any direct contact between the terminal end of the threaded bushing and the juxtaposed portion of the boot member.
