A pressing device includes a base board, an upper board unit that is disposed over the base board, and an intermediate unit that is disposed between the base board and the upper board unit. The upper board unit includes a panel, a circuit board, and a tact switch. The intermediate unit includes a middle portion that corresponds in position to the tact switch, a surrounding frame member, and a plurality of interconnecting board members. When the upper board unit is pressed, at least one of the interconnecting board members is deformed, and the middle portion is driven to convert the tact switch from an initial state to a triggered state.

A rotational operation unit includes a rotational operation member that is rotatable, an annular magnet configured to integrally rotate with the rotational operation member, and a magnet holding member configured to rotatably hold the magnet and including an undulated portion configured to generate a click sense as the rotational operation member rotates. The magnet includes a positioner configured to determine a position relative to the magnet holding member.

A switch assembly including a socket, a top cap, and an intermediate cart located in the socket. The intermediate cart is slidable with the socket. The top cap is in a spherical or pivot engagement with the intermediate cart. An activation force of the sliding movement is lower than an activation force of the spherical or pivot movement.

A lever switch which is capable of preventing loud operating noise from being generated during stepwise operation of an operating lever. The lever switch has a case, a click feeling generator placed inside the case, and a switch moving body placed inside the case and rotated with respect to the case by operating the operating lever. The click feeling generator has trough portions that abut against a convex portion of the switch moving body. Click feelings are given by the convex portion of the switch moving body sequentially abutting against the trough portions in response to stepwise operations of the operating lever. The convex portion of the switch moving body is urged toward the click feeling generator. The click feeling generator and the case are placed away from each other with a space left between them in a direction in which the first case is urged.

The present disclosure provides an intelligent lighting control system for temporarily opening a circuit in the system. The lighting control system includes a light switch module including a switch control circuit. The switch control circuit includes a processor configured to modulate the flow of electrical energy to the lighting circuit via a dimmer circuit to produce a plurality of lighting scenes by varying the illumination of the light bulb. The processor is, in response to receipt of a control command to discontinue illumination of the light bulb, configured to cause, for a first pre-specified period of time, the amperage of the current flowing from an alternating current power supply to the power circuit to be reduced, and open, for the first pre-specified period of time, the electrical connection between the switch control circuit and an electrical connector.

A keyboard includes a plurality of keyswitch structures and an adjusting plate movably disposed under the keyswitch structures. Each of the keyswitch structures includes a tactile feedback member. The adjusting plate includes a plate body and a plurality of adjusting bars protruding from the plate body toward the keyswitch structures and respectively corresponding to the tactile feedback members of the keyswitch structures. When the adjusting plate moves relative to the keyswitch structures, the adjusting bars drive the tactile feedback members to change tactile feedback of the keyswitch structures.

The present invention provides a micro tactility-simulating sensing device, including: a chip including a first top surface and a first inductor, wherein the first top surface has wiring through holes configured to allow an external circuit to connect to the first inductor, and the first top surface is a flat surface except the wiring through holes; a magnetic rigid body coupled with the first inductor to allow the first inductor to sense a magnetic flux passing therethrough, and configured to receive a tactile load; and a polymer configured between the chip and the magnetic rigid body to have a characteristic distance therebetween, wherein the characteristic distance and the magnetic flux have a functional relationship. The micro tactility-simulating sensing device of the present invention can effectively increase the magnitude of the measured signal and provide two different ways to read the signal.

A multi-directional input device includes an operation knob, a plurality of direction setting switches, and a sensation generation unit. The operation knob is configured to be operable in multiple operation directions. The plurality of direction setting switches are configured to be turned on by being pressed when the operation knob is operated. The sensation generation unit is configured to generate different operation sensation from operation sensation generated by the direction setting switches. Sensation is generated by the sensation generation unit after at least one of the plurality of direction setting switches has been turned on in a predetermined operation direction out of the multiple operation directions.

Provided is a lever switch with an improved operation feeling. In the lever switch, a clicking surface of the click feeling generator abuts with an end portion of a switch moving body turning about a turn fulcrum in response to an operation of an operation lever, and generates a click feeling by causing a reaction force against the operation of the operation lever. A region of the clicking surface forms a shape of a curved face convex toward the turn fulcrum, where the region ranges between a first position where the reaction force starts to decrease from the peak and a second position where the reaction force becomes zero, in a stroke in which the switch moving body turns from a first angle to a second angle. The radius of curvature of the region is the maximum at a portion adjoining the first position in the region.

A keyboard includes a base, a keycap, and a connecting assembly. The keycap is located over the base. The connecting assembly is located between the base and the keycap and includes a first connecting member and a second connecting member connected to each other. Each of the first and second connecting members is connected to the base and the keycap. Two connected members of the base, the keycap, and the first and second connecting members are fixedly connected. When the keycap is pressed toward the base, at least one of the first and second connecting members elastically deforms to store elastic potential energy. When the keycap is released, said at least one of the first and second connecting members elastically recovers to return the keycap to its original position.
