A plurality of switchable contacts are provided on a relaying printed circuit board for centralized relaying of signals between a vehicle per se and a switch unit; a plurality of contact change-over members for connecting and disconnecting the switchable contacts are mounted on this printed circuit board; a drive member oscillatable from outside to inside of a box-shaped housing is fitted to each end of the housing in a lengthwise direction; the printed circuit board is fixed to an outer part of an under face of the housing to cause the contact change-over members to face the inside of the housing; the drive members and the contact change-over members are engaged with each other to oscillate the drive members; and the switchable contacts on the printed circuit board are thereby changed over.

Composite switch unit for vehicle use provided with swingable drive members at both ends in lengthwise direction of box-shaped housing

The turn signal switch device is provided with: a housing; an operating lever rotatably supported by the housing; a first cancel lever which is rotated by abutting a cancel protrusion on a steering wheel side; and a second cancel lever rotatable in interlock with the first cancel lever, wherein a protrusion shaft or an elongated hole of the second cancel lever is inserted in an elongated hole or the protrusion shaft provided in a bottom plate of the housing, and wherein in order that both ends may be exposed in the elongated hole, the protrusion shaft is caught between both ends of the second spring mounted to the bottom plate or the second cancel lever to be held at a central position of the elongated hole.

Turn signal switch device for automatically restoring operating lever from operating position to neutral position

A rotatable connector in which a moving body provided with first and second openings are rotatably arranged within a storage section defined between a stationary housing having an outer cylindrical wall and a movable housing having an inner cylindrical wall; and the width W,of the first opening and the width W,of the second opening are set as W,<W,. The first and second flat cables with both ends thereof fixed on the peripheral surfaces of the outer cylindrical wall and the inner cylindrical wall are wound within the storage section. The turned-back portions of the flat cables are routed through the first and second openings, with the inner end of the first flat cable directly wound around the peripheral surface of the inner cylindrical portion and with the inner end of the second flat cable also wound on the inner cylindrical portion through about one turn of the flat cable, thereby changing the winding diameter of the flat cables in relation to the inner cylindrical portion.

Rotatable connector

A rotary connector including a moving member (5) provided with first and second openings (14, 15) which is disposed in a holding space (10) formed between a fixed housing (1) having an upper case (6) and a movable housing (2) having a lower case (7) such that the moving member coaxially rotates with the movable housing (2) relative to the fixed housing (1). A width (W.sub.1) of the first opening (14) is made smaller than a width (W.sub.2) of the second opening (15) (i.e., W.sub.1 &lt;W.sub.2). First and second flat cables (3, 4) are wound in the holding space (10) and have both ends thereof respectively fixed to the peripheral surfaces of the upper case (6) and the lower case (7), and reversal portions (3a, 4a) of the flat cables (3, 4) are passed through the first opening (14) and the second opening (15). The first flat cable (3) is directly wound on the cylindrical section (9) of the first flat cable (3), while the second flat cable (4) is wound on the first flat cable (3) so that the flat cables (3, 4) have different winding diameters relative to the inner cylindrical section (9).

Rotary connector

A rotary connector which prevents separation of a resilient tongue from a flexible cable so as to prevent buckling. The rotary connector includes first and second housings rotatably connected together and forming an annular space therebetween. A flexible cable and a movable member are received in the annular space. The movable member includes a turntable having a stationary cylinder and a reversing roller, the stationary cylinder including a guide projection. The flexible cable is wound in opposite directions on opposite sides of the movable member and includes a U-shaped reverse portion extending through a gap between the stationary cylinder and the reversing roller. A resilient tongue having a free end portion substantially formed in a linear shape in an unloaded condition is affixed to an inner surface of the flexible cable and to an inner cylinder portion of the second housing. An amount of deformation of the free end portion when it is bent between the stationary cylinder and the reversing roller can be reduced, thereby preventing separation of the tip of the resilient tongue from the flexible cable.
