Abstract
Encapsulated switches are disclosed which substitute non-toxic gallium alloy for mercury. In one embodiment, wetting of the interior surfaces of the housing is prevented by coating the surfaces with an electrically insulative inorganic non-metallic material, such as alumina or boron nitrate. According to another embodiment, a perfluorocarbon liquid is employed as the anti-wetting agent.
