A switch that includes an illumination structure that extends at least partially around a perimeter of the switch. The illumination structure being illuminated based on the status of the switch. The switch also including a switch surface that includes a transparent or translucent material that can be illuminated based on the status of the switch. The switch being adapted for use in a wet or damp environment.

Methods, systems, and devices are disclosed for implementing a fiber-waveguide evanescent coupling. In one aspect, a device having integrated photonic components includes a substrate, a waveguide formed on the substrate to include a terminal waveguide portion that terminates at one side of the substrate, and a fiber including a fiber core and fiber cladding surrounding the fiber core, in which at least a portion of the fiber cladding is removed at or near a fiber terminal end to enable optical evanescent coupling via a side surface of the fiber core at the or near the fiber terminal end, the fiber core at the or near the fiber terminal end is placed over the one side of the substrate to be above and to overlap with the terminal waveguide portion of the waveguide to enable optical evanescent coupling via side surfaces of the fiber core and the waveguide.

A overload protection switch with a reverse restart switching structure that has a seesaw lampshade provided with a protruding block which extending downward from the outside of the seesaw lampshade to ensure that the seesaw lampshade and the moving rod are accurately positioned in the ON and OFF positions in the housing to form a three-stage switching type with bidirectional positioning and forms an overload protection switch that can continuously maintain sufficient insulation distance and does not reduce the insulation distance due to fatigue decay of the binary alloy conductive plate.
