A lighting device and system having a faceplate and a backplate. The faceplate or the backplate may have an arm or a set of arms having electrical conductors to connect or couple to the electrical contact points of an outlet, plug, or switch. The operational modes may be in an emergency lighting mode and a nightlight mode. The voltage source can be connected to a light source or sensor through the control circuit or the switch, and the light source may be activated based on the output of the sensor. A controller is connected to the sensor can send or receive wireless signals through a wireless module.

An engine starting device includes a board on which a pin header serving as an on-board component is mounted, a case member that has a tubular shape and that is disposed so as to surround the board, and an antenna coil that is disposed in the case member and that is electrically connected to an antenna terminal partly embedded in the pin header serving as an on-board component.

The disclosure provides a keyboard including a bottom plate, a key unit and a shielding layer. The bottom plate includes a through hole. The key unit is disposed on the bottom plate. The shielding layer covering a portion of the bottom plate includes a main part and an extension part extending from the main part toward the through hole. The shielding layer is provided with a black surface, and an orthographic projection of the key unit on the shielding layer overlaps the black surface.

An electrical switch shield includes a base extending along a lateral axis and a longitudinal axis. The electrical switch shield includes a plurality of legs extending from the base along a vertical axis. The electrical switch shield includes a first clip and a second clip at opposing lateral sides of the base and spaced from each along the lateral axis.

An enclosure adapter for a circuit breaker that converts a panel mounted circuit breaker to a flat surface mounted circuit breaker. The enclosure adapter has a housing with a top end, an open bottom end, and sides defining an interior. The open bottom end allows for insertion of a circuit breaker into the interior. The top end has an opening to provide access to controls on the circuit breaker and has openings for attaching the circuit breaker to an interior side of the top end. Mounting members are formed at the bottom end of the enclosure adapter to mount the enclosure adapter to a flat surface. The sides form corners which are indentations into the interior of the enclosure adapter and the mounting members are formed in the indentations, wherein the indentations facilitate mounting the enclosure adapter to a flat surface. Removable tabs create openings for electrical connections.

An enclosure assembly for isolating an electrical interface includes a cover plate adapted to frame the electrical interface or a box form having an open end leaving open access to the electrical interface, and a dome cover dimensionally and geometrically adapted to connect to the cover plate or box form via a pair of materially flexible, locking tabs having thicker interfacing edges and thinner tab bodies spaced-apart and aligning with a pair of connector through slots on the cover plate or box form, the cover dome lock able to the cover plate or box form.

A power switch including a contact configured to selectively electrically connect a line input to a load output, a switch configured to selectively control the contract, and an indicator. The contact has a closed position in which the line input is electrically connected to the load output, and an open position in which the line input is not electrically connected to the load output. The switch has an on position wherein the contact is controlled to be in the closed position, and an off position wherein the contact is controlled to be in the open position. The indicator provides a normal on status, a normal off status, and an error on status.
