A keyboard includes a base plate, a key module, a light source and an insulation layer. The base plate has a first side and a second side opposite to the first side. The key module is disposed on the first side of the base plate. The light source module includes a first light source and a second light source disposed on the second side of the base plate. The insulation layer is disposed between the base plate and the light source module. The base plate has an opening, the first light source is covered by the base plate along a lifting direction of the key module, and the second light source is disposed at a position corresponding to the opening of the base plate.

The invention relates to an electrical switching device including a nominal contact arrangement, an arcing contact arrangement defining an arcing volume in which an arc-quenching medium is present, an exhaust system including a first exhaust opening connected fluidly to a tank volume, an exhaust channel for dissipating hot medium from the arcing volume into the tank volume, the exhaust system further including a piston arranged in a compression guide and defining on its side opposed to the arcing volume together with the compression guide a compression chamber. An inlet channel is fluidly connected to the compression chamber and extends to an inlet opening fluidly connected to the tank volume, wherein the inlet channel and the exhaust channel are fluidly separated from each other.

An electrical device such as, for example, a battery-powered electrical switch is disclosed. The battery-powered wireless switch includes one or more mechanisms arranged and configured to provide simplified access for servicing (e.g., replacing) the batteries located within the wireless switch. In one embodiment, the wireless switch is arranged and configured so that the batteries may be accessed by reconfiguring the wireless switch from a first closed position to a second opened position to access the batteries. Thus arranged, removal of the wireless switch from a wall-box or a surface of a wall is not required, the user may only need to remove the wall-plate in order to reconfigure the wireless switch. In one embodiment, at least a portion of the wireless switch is pivoted from the first position to the second position to provide access to the batteries.

A keyswitch structure includes a baseplate, a keycap disposed over the baseplate and configured to be movable relative to the baseplate, a membrane switch disposed between the keycap and the baseplate and configured to have one or more buffer portions with two open edges opposite to each other, and a first linking bar connected to the keycap and disposed between the keycap and the membrane switch. The first linking bar has a first long side and a first short side connected to each other. When the keycap moves relative to the baseplate, the one or more buffer portions provide buffer to the first short side and/or an end section of the first long side.

A multi-stage key structure includes a circuit board, a reflective optical component, a base plate and a keycap. The reflective optical component includes a light emitter and a light receiver that are disposed over the circuit board and separated from each other. The base plate is disposed over the circuit board and has at least one first through hole accommodating the reflective optical component. The keycap has a light-blocking reflective member facing the light emitter and the light receiver of the reflective optical component, in which the light emitter is configured to emit a light beam toward the light-blocking reflective member, and the light-blocking reflective member is configured to reflect the light beam to the light receiver.

A switching unit for a power control unit is disclosed, comprising at least one power supply node for connection to a power supply, at least one load node for connection to a load, an electrical current path configured to connect the at least one power supply node to the at least one load node, and a plurality of switches disposed on the electrical current path. Each switch is configured to be independently connected to a controller implementing control logic configured to independently trigger each of the switches to transition between an open-circuit state and a closed-circuit state to modify the continuity of the current path. The plurality of switches are arranged into at least one configurable switch set, each configurable switch set comprising at least two of the plurality of switches, wherein the switches comprised in each configurable switch set are configured to be set into either of a parallel configuration or a series configuration with respect to the electrical current path. A circuit package comprising the switching unit is also disclosed, together with a method of operating a switching unit for a power control unit. In some embodiments, the circuit package is included in an aerosol provision device.
