A system includes a frame and a camera coupled to the frame. The camera includes a switch having an on position and an off position. The switch coupled to the frame wherein when the switch is in an off position a portion of the switch covers the lens and the camera is disable and when the switch is in an on position the portion of switch does not cover the lens and the camera is enabled.

A push-button switch member includes: a movable contact and an operation key disposed facing the protruding side thereof, and in contact therewith or spaced therefrom. The movable contact includes: an upper contact portion disposed directly under a key body; an outer fixed portion in the upper contact portion or more outward therefrom in the radial direction, and fixed more outward in the radial direction than the key body; and a non-contacting outer portion provided more outward in the radial direction than the upper contact portion, and disposed to face in a non-contacting state another contact so as to be able to contact another contact which is disposed on an outer side in the radial direction and contacted by the upper contact portion when pushed by the key body. The non-contacting outer portion has a bottom portion for a line contact or a surface contact with another contact.

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.

An information capturing device includes a housing, a rotary knob, a magnetic ring, a circuit board, a video recording unit, a control unit and a Hall sensor. The rotary knob is rotatably provided on the housing. The magnetic ring is located between the housing and the rotary knob, and includes plurality of magnetic poles, wherein magnetic poles of two different polarities are in a staggered arrangement along a ring shape. The circuit board is located in the housing. The video recording unit is provided on the circuit board and is embedded on the housing. The control unit is located in the housing and provided on the circuit board, and is coupled to the video recording unit via the circuit board. The Hall sensor is located in the housing and located on the circuit board correspondingly to the magnetic ring, and is coupled to the control unit via the circuit board.

A pressing switch mechanism includes a housing, a board that is accommodated in the housing, a switch portion that is fixed to the board and generates a click feeling according to pressing a pressed portion in a direction approaching the board, and an operation plate which includes a bowl-shaped recessed surface that is recessed from a surface of the housing, of which an outer peripheral edge is supported by the housing, which is displaceably bent in the direction approaching the board, and in which a bottom wall portion of the recessed surface protruding inward the housing is in contact with the pressed portion.

A light structure for an electronic device includes a first portion permitting user access to a button of the device; and a second portion surrounding the first portion, wherein the second portion permits light from a light source to pass through. The light passing through the second portion varies according to a condition of the electronic device.

A camera-assisted collimated beam alignment system for aligning first, second and third insulators of an electric power disconnect switch. An emitter stage including an emitter is temporarily attached to the first insulator. An aperture stage including an aperture plate with alignment aperture is temporarily attached to the second insulator. A target stage including an alignment target is temporarily attached to the third insulator. A camera is positioned to capture an image of the aperture plate displays an alignment indicator projected by the emitter onto the aperture plate. A camera viewer spaced apart from the camera displays the image captured by the camera to assist a technician when adjusting alignment of the insulators.

An electronic apparatus includes a first operation unit and a second operation unit each operable by a user. The first operation unit is configured to change a state of at least one switch when operated. The second operation unit is configured to change a state of a first switch according to a first operation, and a state of a second switch according to a second operation following the first operation, with an operating force greater than that of the first operation. A maximum value of the operating force for the second operation with the second operation unit is different from a maximum operating force for operating the first operation unit.

An operation device includes a dial and a dial lock member including a recessed portion. The dial includes: a lock lever member that is movable in an extending direction of a rotational center line of the dial and includes a button portion and a projecting portion, the button portion being configured to be pressed down by a user, the projecting portion being configured to engage with the recessed portion of the dial lock member to bring the dial into a non-rotatable locked state when the button portion is pressed down; and an alternate mechanism configured to moves the lock lever member so as to bring the dial into a rotatable unlocked state in which engagement between the projecting portion and the recessed portion is released after the button portion in the locked state is pressed down by a user.
