An electrical switch for providing power from a power source to a component may include a voltage supervisor having an input and an output, a voltage divider, electrically coupled between the input of the voltage supervisor and ground, an RC filter electrically coupled to the output of the voltage supervisor, and a field-effect transistor having a first terminal coupled to the RC filter and a second terminal coupled to an output of the switch, the output configured to be electrically coupled to the component. A switch may additionally or alternatively include a light source electrically that emits light when power is provided from the input of the switch to the component, the light source arranged proximate a fuse so as to illuminate the fuse.

A lens, a vehicle lamp, and a corresponding vehicle, the lens including a lens portion with a touch area and an antenna portion including a flange portion, the antenna portion being electrically conductive and at least partially opposite to the touch area. When the touch area of the lens provided with the antenna portion is touched, the capacitance of a capacitor formed by the antenna portion will change.

A distributed induction-controlled solar lighting system comprises a first light, second lights and an inductive switch. Each light comprises a first sensor and a sub-controller used for controlling the brightness of the light. The inductive switch is spaced apart from the first light and can trigger the brightness of the first light within its preset range to increase when sensing that a pedestrian or an animal passes by. The first sensor can trigger the brightness of the first light and/or the second light within its range to increase when sensing that a pedestrian or an animal passes by. The solar lighting system can sense a signal in advance when a pedestrian or an animal passes by, such that the situation where the lights will not be turned on or brightness will not be increased until a pedestrian or an animal passes by is avoided; each light has a brightness adjustment function and can adjust the brightness of its own according to a sensing signal of the adjacent lights, a special master controller is not needed, unnecessary lighting power is avoided, and the endurance and reliability of the lights are improved.
