Embodiments disclosed herein describe a base, an operation unit that moves in a contacting/separating direction with respect to the base in response to an external force, and a pair of link members turnably coupled to each other by a coupling portion and configured to guide movement of the operation unit in the contacting/separating direction. The pair of link members includes a first curved portion and a second curved portion that are supported on the base, and a first rotary spindle and a second rotary spindle that are supported on the operation unit. When the operation unit moves in the contacting/separating direction with respect to the base, the first curved portion and the second curved portion slide with respect to the base in a direction substantially perpendicular to the contacting/separating direction and in a direction substantially perpendicular to a turning shaft of the pair of link members.

Switch and keyboard

A key switch device includes a base, a button mounted on the base so as to be contactable and separable, an elastic body disposed between the base and the button and configured to urge the button in a direction away from the base, and a linear reinforcement member provided on the button and configured to prevent the button from being inclined when the button is operated in a direction toward the base. An outer surface portion of the button includes a recessed support portion in which a part of the linear reinforcement members is disposed.

Key switch device

A key switch device includes a base including an opening in a central part thereof; a light guide including an elastic body receiving portion, the light guide being supported by the base to be disposed in the opening; a button attached capable of approaching and separating from the base to cover the light guide; an elastic body disposed between the elastic body receiving portion and a lower surface of the button, the elastic body biasing the button in a separating direction where the button is separated from the base; a fixed contact piece including a fixed contact, the fixed contact piece being attached to the base; and a movable contact piece, which is attached to the base, including a movable contact to be brought into contact with the fixed contact when the button is moved toward the base in an approaching direction where the button approaches the base.

A switch has a base, an operation unit disposed on the base and moving in a contacting-separating direction with respect to the base in response to an external force, and a link member configured to guide movement of the operation unit in the contacting-separating direction and support the operation unit on the base. The base includes a base-side latching portion. The operation unit includes an operation-unit-side latching portion configured to be latched to base-side latching portion at an end of an allowable movement range for the operation unit in a separating direction in which the operation unit is separated from the base. The base-side latching portion and the operation-unit-side latching portion are latched to each other to inhibit the operation unit from moving in the separating direction beyond the separating-direction end of the allowable movement range.

Push button switch with operation unit latched to base

A switch has a base, an operation unit disposed above the base and moving in a contacting-separating direction with respect to the base in response to an external force, a pair of link members configured to guide movement of the operation unit in the contacting-separating direction, and a coupling portion configured to turnably couple the pair of link members to each other. Each of the pair of link members each includes a coupling-portion-side supported portion supported on one of the base and the operation unit and an end-side supported portion supported on the other of the base and the operation unit. One of the base and the operation unit on which the coupling-portion-side supported portion is supported includes a wall surface provided with a movement space.

Keyboard switch link member configuration

A push button switch includes a housing made up of a base and a cover, a first plunger mounted on the cover so as to be pushed down, a movable contacting piece configured to be driven by a push-down operation on the first plunger, a movable contact provided in the movable contacting piece, and a fixed contact disposed so as to come into and out of contact with the movable contact. Specifically, the movable contacting piece includes a movable contact piece provided with the movable contact, and an operation tongue piece disposed on at least one side of the movable contact piece and coupled with the movable contact piece so as to rotate integrally. The operation tongue piece is operated by the operation body of the first plunger to bring the movable contact into and out of contact with the fixed contact.

Push button switch

A power-generating module has a base, a power-generating unit that is placed in the base, a plunger that is placed in the base and that vertically reciprocates, and a drive section that interlocks with the reciprocation of the plunger and starts up the power-generating unit. The drive section is biased to a boost-up position where the plunger is boosted up. The drive section has at least two links that turn between the boost-up position and a press-in position where the power-generating unit is started up. Both ends of one of the links are turnably supported by the base. Both ends of another link are turnably supported by the plunger. The links turn in an interlocking manner by coupling to each other.

Push switch

An aspect of the present invention provides an electric magnet device, in which a smooth movement of an armature is ensured and, even if a vibration or an impact is applied, an attraction state between a yoke and the armature is maintained to prevent a malfunction, and a switch provided therewith, where the electric magnet device includes: a coil adapted to insert through an armature and a yoke so as to attract surfaces of the yoke and the armature, which are opposed to each other, to receive a voltage, to excite for separating the surfaces of the yoke and the armature; the armature disposed on one end side of the coil; and the yoke disposed on the other end side of the coil and adapted to oscillate, such that an oscillation angle of the yoke is greater than that of the armature.

Electric magnet device and switch provided therewith

A push button switch has a housing formed by a base in which a fixed contact is disposed on a bottom face of the base and a cover assembled to the base, an operating member slidably inserted in the housing parallel to the bottom face of the base, a guiding part formed on the cover, extending obliquely inwards from a ceiling face of the cover, wherein a tip of an operating piece of the operating member is operable to slide along the guiding part, and a movable contact disposed in the housing and operable to be pressed against the fixed contact, thereby opening a circuit. The guiding part and a reinforcing part extending from the ceiling face of the cover at least on one side of the guiding part are formed at an edge of a through hole formed in the ceiling face of the cover. The movable contact has a thin dome shape.
