A harness assembly includes a plurality of individual wires and a restriction mechanism. The restriction mechanism has a sleeve member surrounding each of the plurality of individual wires in order to prevent longitudinal movement of each of the plurality of individual wires with respect to each other. Each of the plurality of individual wires has a helical-shaped portion located internal with respect to the sleeve member, thereby allowing each of the plurality of individual wires to engage the sleeve member.

A terminal is provided for an electrical switchgear. The terminal includes: a housing arrangement including an electrically insulating material and having an inner surface defining a cavity; and a first terminal electrical contact contained in the housing arrangement for making an electrical connection with an electrical component insertable into the cavity. The first terminal electrical contact is located in a first recess formed in the inner surface, the first terminal electrical contact being flush with the inner surface.

The present invention provides a switch having a small longitudinal size of movable contacts and reduced size. The switch includes a base, a pair of fixing terminals standing on an upper surface of the base, an insulating wall section integrated with at least one of the fixing terminals, a push button arranged to be upward and downward movable in the axial direction, and a slider movable upward and downward with the push button. The slider has elastic arm sections in both ends thereof, the elastic arm sections being provided with movable contact portions to be brought into sliding contact with the fixing terminals or the insulating wall section while pressing the fixing terminals or the insulating wall section from one side The switch is configured to enable the movable contact portions to connect to and separate from the fixing terminals based on operation of the push button upward and downward.

A lever switch has a base member, a first switch knob member, a first moderation mechanism, a substrate having a first contact member, and a first slider. The base member has a first supporting surface formed along an outer peripheral surface of a column centered on a rotational axis of the first switch knob member and a second supporting surface formed on one side across the rotational axis. The first switch knob member includes a first supported surface and a second supported surface, and the second supported surface is provided with a first cam portion. The first supported surface is rotatably supported on the first supporting surface, the second supported surface is rotatably supported on the second supporting surface, and the first slider is held on a side opposite to a side where the second supporting surface is provided across the rotational axis.

A lever switch includes a case, a lever, a wiring board, a sliding body, and a movable contact. The wiring board has fixed contacts and is disposed at an opposite side to the lever with respect to the case. The sliding body has a sliding part and a second arm part having a supporting portion, and is disposed between the case and the wiring board. The movable contact is mounted to the sliding part and has an end to be brought into contact with the fixed contact. A first arm part of the lever extends from the main body part through the case and the wiring board. The second arm part extends from the wiring board through the sliding part. The holding portion and the supporting portion are engaged with each other at an opposite side to the case with respect to the wiring board.

A slide switch is provided that is more excellent in reliability than conventional techniques. A slide switch senses an extracted state and an inserted and engaged state of an object. The slide switch includes a body, a slider, a terminal, and an armature. The slider is slidably held in the body and is pushed by insertion of the object to slidingly move. The terminal is provided with a fixed contact point disposed on a surface, facing the slider, of the body along a sliding movement direction. The armature is attached to the slider and is provided with a moving contact point that slides on a fixed contact point disposition surface of the body in association with sliding movement of the slider. In the entire range of the sliding movement, the body and the slider cover all around the fixed contact point and the armature.

A portable electronic device (10) is provided. The portable electronic device includes the keypad assembly (20). The keypad assembly includes key buttons (30 or 60). Each key button includes a key portion (32 or 62), a supporting portion (34 or 66), a switching portion (35 or 64), a pad portion (36 or 67), and a circuit board portion (38 or 68). The supporting portion defines a first through hole (344 or 664). The switching portion includes at least one switching elastic sheet (354 or 644). The pad portion includes a base body (362 or 672) and a protruding portion (364 or 674). The circuit board portion includes a first contacting point (3821 or 6821), a contacting sheet (384 or 684), and at least one second contacting point (3822 or 6822).

A contact structure for a sliding switch includes a conductive stationary contact disposed on a base and a conductive movable contact for electrically contacting the stationary contact. The movable contact is movable along a path between a non-contact position and a make-contact position with respect to the stationary contact, and at least one of the contacts has a protruding portion that provides an electrical interface for discharge of arcing as the movable contact breaks from the stationary contact. As a result, the invention prevents or substantially reduces degradation in switch performance which might otherwise be caused by debris accumulation associated with arcing.

A pushbutton switch is disclosed which may be used, for example, in a camera. The switch has multiple positions which can be easily sensed by the operator as a point of resistance which is felt at each position. The switch may have an axially moveable spring biased switching rod at a defined electrical potential with an insulated region. A plurality of spring biased electrical contacts bear radially against the switching rod. A plurality of spring biased stops extending radially toward the path of axial movement of the switching rod correspond to the respective electrical contacts. Axial movement of the switching rod brings the contacts into successive contact with the conducting portion of the switching rod. The spring biased stops bear against the end of the switching rod at approximately the points of axial movement at which their corresponding contacts make contact with the conducting portion of the swiching rod, thereby generating a counterpressure which may be sensed by an operator of the switch. The stops may be deflected from the path of axial movement of the switching rod through axial movement of the switching rod, allowing the successive switch positions to be attained.

A manual switch (2) has a switching plate (9), which can be tilted to several sides and is mounted on a mounting (10). This switching plate (9) can move with star-shaped actuating arms that correspond to the contact arms of a contact spring (7) in the direction of a printed circuit board (6), so that it can close a circuit by means releasably, lockingly engaging the selected actuating arm against a respective contact arm and an electric contact on the printed circuit board. At any switch position one can switch back directly into the zero position by pressing an adjusting arm (13) which moves the switching plate (9) back into its non-tilted position.
