A switch device includes an actuation unit, a movable unit, a first base, and a second spring, which is a torsion coil spring that acts between the actuation unit and the movable unit. The movable unit is movable with respect to the base. The second spring applies a force to the actuation unit when the actuation unit is at a third position in a direction that is not parallel to a direction in which the torsion coil spring applies a force to the actuation unit when the actuation unit is at a fourth position.

A power generation device including a rotation member rotatable by an operation force and a supporting member supporting the rotation member by attracting the rotation member with a magnetic force, the power generation device inducing a current to a coil by a magnetic flux of a magnet caused by rotation of the rotation member, and where, when the operation force is applied in a first state in which the rotation member is supported by the supporting member by being attracted to a first and second portions of the supporting member at respective first and second positions, the rotation member transitions to a second state by rotating with the first position of the supporting member as a first supporting point, and further transitions to a third state by rotating with a position of the supporting member different from the first position as a second supporting point.

Power generation device, transmission device, switching device

A switching device that causes a force to act on an arc to diffuse the arc, has a magnet that generates a magnetic field in a direction orthogonal to a direction of the arc, the arc being generated at moment at which a movable member is brought into contact with or separated from a contact of a fixed member to switch between electric conduction and electric cutoff. The magnet is a plastic magnet in which metal is exposed to a surface of the magnet.

Switching device

An input device has a housing having an operation hole formed therein, an operation member supported in a slidably moving manner in multi-directions within the operation hole, and at least two magnetic sensors, arranged at a periphery of the operation member, for detecting change in magnetic property by displacement of the operation member. The operation member includes a holder having a circular ring-shaped magnet incorporated in a fit-in hole and a central push button having a disc plate made of magnetic material integrated at a lower surface. The central push button is fitted in the circular ring-shaped magnet to adsorb, in a separable manner, the disc plate to the circular ring-shaped magnet and position-regulate the central push button.

An operation input device includes a base, a printed circuit board which has a plurality of pushbutton switches and Hall elements mounted on its upside and which is stacked on and united with the base, an operation plate which is supported on the base so as to be vertically movable on the printed circuit board, and a disc type operation dial in which an annular magnet with N-poles and S-poles arranged alternately is assembled on the underside of this operation dial and which is turnably assembled on the upside of the operation plate. Here, the disc type operation dial is turned, thereby to sense the changes of the magnetic fluxes of the annular magnet by the Hall elements and to detect a turning direction, while the disc type operation dial is depressed, thereby to operate any of the pushbutton switches through the operation plate. The operation dial is prevented from becoming rickety in a horizontal direction, and it ensures a smooth turning operation, thereby to afford a good operation feeling.

A rotating and pressing operation type electronic component has a reduced size, but without lowering workability, reliability of contact, and operability, wherein an inner contract formed of a tubular conductor and formed by extending, parallel with each other; a plurality of extension parts from an opening edge part along the axis thereof at specified angular pitches is inserted into a rotating operation body and formed integrally therewith. The elastic contact parts of two contact pieces are disposed on the inner peripheral surfaces of the extension parts of the inner contact so as to contact these inner peripheral surfaces, and the elastic contact parts of a common contact piece are disposed on the inner peripheral surfaces of the inner contact excluding the extension part so as to be always brought into contact with the inner peripheral surfaces.

In the supporting structure of fixed contact terminals, a pair of fixed contact terminals with respective fixed contacts provided on their free ends are supported by fixed contact bases and the both ends of a movable contact piece contact with and separate from the pair of the fixed contacts. Cut-off grooves are provided on the surfaces of the fixed contact bases at each position near the fixed contacts, and they are formed in a converted T shape on a cross section, partitioning the pair of fixed contact terminals.

Supporting structure of fixed contact terminals

An electromagnetic relay has an iron core having a protruding shaft and a magnetic pole portion. The protruding shaft is penetrated through a through hole provided on a metal case, and coil is wound around the protruding shaft. A voltage is applied to the coil for magnetization and stopped for demagnetization, hence to drive a contact mechanism with a movable iron piece that is attracted by and separated from the magnetic pole portion, thereby causing a reciprocating motion of the movable iron piece. The relay can prevent generation of eddy current.
