A power tool includes a tool-main-body part, an electric motor as a drive source, a grip part, which extends downward from the tool-main-body part and is configured to be gripped by a user, and a power-supply unit at a tip of the grip part. The power tool includes a controller configured to control the operation of the electric motor, the controller being located on the power-supply unit, and a display controlled by the controller and configured to indicate an operating state of the electric motor. The controller and the display each have a flat-plate shape and are disposed along a surface direction with respect to one another, and the display includes a first portion that overlies the controller and a second portion that projects beyond an end edge of the controller.

A push-button switch may include a housing, an operation unit, a lock lever unit, and a biasing portion. A lever support portion may be connected to the operation unit so as to be movable together with the operation unit when a lever body is positioned at a second position. The housing may have a deformation portion that, when the operation unit is pulled in an opening direction when the lever body is positioned at the second position, deforms the lever body so as to be capable of releasing the pressing to the lever body by a holding unit.

The invention relates to an electric switch defining a front surface and including at least two rocker keys, which rock about a corresponding rocker axis, and at least one base provided with at least two operating points for electrical connection and disconnection located at a point corresponding to the center of the corresponding key, where the rocking of the keys presses on the corresponding at least one operating point and causes the electrical connection or disconnection, wherein the key comprises has two sections separated by the rocker axis, a first transmission section of the operating force and a second section that does not transmit the operating force to the operating point, and in that the rocker axes of the at least two keys are parallel to each other.

The keyboard device includes a substrate, a key, a first elastic member, and a second elastic member. The substrate includes a top surface having an assembly area. The assembly area has a pivoting base including a standing portion and an extension portion extending from the standing portion. The key is liftably disposed over the assembly area. A pivoting hook is extending from the bottom of the key toward the assembly area, and one end of the pivoting hook includes a pivoting portion. The first elastic member and the second elastic member are disposed on the assembly area and elastically abutted against the bottom of the key, so that the pivoting portion is abutted against and pivoted to the extension portion, and a liftable distance is maintained between the extension portion and the bottom of the key.

A key module including a base, a circuit layer, at least one light-transmission key body, and a display panel is provided. The circuit layer is disposed at the base and has at least one input portion. The light-transmission key body has an abutting end and a pressing end opposite to each other. The abutting end abuts the base, and the light-transmission key body is adapted to be pressed downward by taking the abutting end as a rotation axis, such that the pressing end presses the input portion. The display panel is disposed at the base and has at least one display region, the display region is aligned with the light-transmission key body, and an image displayed on the display region by the display panel is changeable.

Voice responsive in-wall devices are provided. In one example implementation, a power switch includes a housing mountable on or at least partially within a surface. The housing can have a front panel. The power switch can include an interface element disposed on the front panel and operable to receive a user input. The power switch can include a power interrupter operable to control power delivery to the powered load based at least in part on interaction with the interface element. The power switch can include one or more microphones operable to obtain audio input. The power switch can include one or more speakers configured to provide audio output. The power switch can include a communications interface operable to communicate data associated with the audio input over a communication link.

A lever switch includes a lever main body and a rotary operation element rotatably provided at a tip end portion of the lever main body. The rotary operation element is provided with a light ON switch position at which an instruction to cause head lights and small lights to be on at all times is issued, an automatic light switch position at which an instruction to set an automatic light mode, in which a turned-on state of the head lights and the small lights is controlled based on the intensity of illumination in the vicinity of the vehicle, is issued, and a light OFF switch position at which an instruction to turn the head lights off is issued, the light ON switch position, the automatic light switch position, and the light OFF switch position being arranged in an order along a rotation direction.

An electrical control mechanism having a support. A central body that is movable in rotation about a central axis of rotation (AXROTC) carries a button that is movable in rotation relative to the central body about an offset axis of rotation (AXROTD) parallel to the central axis of rotation (AXROTC). First return means are interposed between the central body and the button, with second return means being interposed between the central body and the support. Two primary electric switches are interposed between the button and the central body on either side of a plane containing the central axis of rotation (AXROTC) and the offset axis of rotation (AXROTD). Two secondary electric switches are interposed between the support and the central body on either side of the plane.

An input device includes a base plate and a push button rotatably provided on a top surface of the base plate. The base plate has a bearing part protruding from the top surface. The push button has an operation surface part receiving a push down operation and a positioning part rotatably supported by the bearing part. The positioning part positions the push button in the plate thickness direction of the bearing part by an abutting part abutting on a first face of the bearing part and a pushing part resiliently biased toward and pushing a second face of the bearing part.

Electrical switch devices are installed at in-wall electrical boxes of a building. Each device features a switch module with multiple electrically controlled switches for respective connection of multiple load circuits. A control panel with a user interface is mountable over the electrical box and is connected or connectable to the switch module. A communications transceiver of each device is operable to transmit and receive communications to and from each of the other devices. The control panel has a touch-screen display, and is configured to display virtual on-screen switches, including at least one virtual switch whose output is assigned to a respective one of the electrically controlled switches of the other devices. The at least one virtual switch at one device is thereby operable to control at least one load at another of said devices. User selected names are assignable to the switches, and used to label the virtual switches.
