Island switch

摘要

A magnetically actuated pushbutton switch has individual switch modules pre-assembled as standalone subassemblies. Each subassembly has a platform with a cavity on its underside. A portion of the platform is magnetized. A metallic armature is held in the cavity by the magnetic attraction of the platform. The switch subassemblies are mounted on a substrate that has switch contacts thereon. The armature is movable into and out of shorting relation with the contacts. A major spacer on the substrate has openings aligned with the switch contacts for receiving the subassemblies. An overlay film covers the subassemblies and major spacer. The armature may have a lens therein for transmitting backlighting. The platform can be magnetized at the time of installation on the substrate.
