Those portions of an upper surface of a bottom wall ( ) of the lower casing ( ), opposed respectively to switch-mounting portions ( to ) of the upper casing ( ), are defined by flat surfaces, respectively, and electronic parts ( ) are mounted in a concentrated manner on those regions of the FPC ( ) disposed respectively on the flat surfaces ( ) of the lower casing ( ).

Switch unit with membrane type, flexible printed circuitry

In a vehicle ceiling-mounting electric equipment assembly of the invention, an FPC ( ) is welded by heat to a casing ( ) of a lamp unit ( ), and an FFC ( ) for external connection is electrically connected to the FPC ( ) by press-clamping or welding. Switches ( ) and lamp socket holes ( ) are provided at the FPC ( ). An end portion of the FPC ( ) is folded to be inserted into a fitting portion ( ) of a recess-shape in which an optional member ( ) can be mounted, and a circuit pattern is exposed to a side surface of the fitting portion ( ) to form a connection portion. Therefore, the compact, lightweight design can be achieved, and parts, such as a connector, are unnecessary, thus reducing the number of the component parts.

Vehicle ceiling-mounting electric equipment assembly

A standard circuit unit for controlling standard electronic equipment (such as a power window drive mechanism), mounted on a door trim , is separate from an optional circuit unit for controlling an optional electronic equipment (e.g. a power seat-adjusting mechanism) optionally mounted on the door trim. A switch circuit board is integrally formed in a predetermined pattern on an extension of an input/output signal conductor portion of an FPC body of each of the two circuit units and First and second electric connectors and , provided respectively at distal ends of the input/output signal conductor portions and , can be combined together with a one-touch operation, and operating signals are inputted from a door control unit via these electric connectors so as to output switch signals for effecting the on-off control of the electronic equipments. When the kind of car is changed, only the optional circuit unit is easily exchangeably combined with the already-mounted standard circuit unit

Circuit connection structure of automobile door

A switch unit is provided, which includes: an operative body being swingingly operably provided; a pair of first switch portions being abuttable on respective end portions of the operative body when the operative body is swingingly operated so as to output signals to raise and lower, respectively, a window glass; a pair of second switch portions arranged apart from a line connecting the pair of first switch portions and nearer a longitudinal middle portion of the operative body than the first switch portions and being abuttable on the operative body when the operative body is swingingly operated so as to output signals to raise and lower, respectively, the window glass; and a pair of supporting portions arranged opposite to the pair of second switch portions with respect to the line, wherein the supporting portions abut on respective portions of the operative body when the first switch portions abut on the respective end portions of the operative body.
