A safety switch includes a detection unit, an output unit, an input unit; and a display unit. The detection unit is configured to detect presence or absence of abnormality. The output unit is configured to output an abnormality detection signal indicating a detection result of the presence or absence of the abnormality. The input unit is configured to input a display control signal. The display unit is configured to perform display based on the display control signal.

To improve toughness of a non-contact type safety door switch. A safety switch includes a metallic casing integrated as a first part of an enclosure, having an opening in a front side, a cover integrated as a front part of the enclosure, covering the opening, the cover having a surface as a front surface of the enclosure, a wireless means, a determination means, an output means, circuit substrates provided inside the metallic casing and the cover, on which the wireless means, the determination means and the output means are mounted, and attachment holes on a side surface of the metallic casing, the side surface being adjacent to the front surface of the enclosure for attaching the casing.

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.

To ensure omnidirectional visibility of a proximity sensor with high luminance using a single light emitting element. A proximity sensor (1) includes a substrate (14) on which a control unit (20) is formed and in which a normal direction of the substrate is perpendicular to an axial direction of a coil section (13), a light emitting element (15) which emits light in the axial direction on the substrate, a light diffusion section (16a) which diffuses emitted light in a direction other than the axial direction, and a light guide section (16b) which guides diffused light to a display section (21) on a side surface.

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.

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.
