  • Toggle switch having improved moulded sealing component, and assembly with such a toggle switch and a support panel
    Patent number: 10128066
    Abstract: A toggle switch includes a hollow base, a switch mechanism, a cover, a bushing extending from the cover, a toggle lever, and a one piece resilient sealing component. The sealing component includes a lever seal surrounding the toggle lever and covering the inner wall of the bushing for sealing a space between the toggle lever and the bushing. A cover seal forms a lower closed sealing ring compressed between the cover and the base for sealing the cover to the base. The one piece resilient sealing component also includes an upper closed sealing ring surrounding the bushing and extending on a portion of the upper surface of the cover for cooperating with a panel for mounting the switch.
