The cost and complexity of an electronic pressure sensitive transducer are decreased by constructing such a transducer directly on a printed circuit board containing support electronics. Conductive traces are formed on the printed circuit board to define a contact area. A flexible substrate having an inner surface is positioned over the contact area. An adhesive spacer, substantially surrounding the contact area, attaches the flexible substrate to the printed circuit board. At least one resistive layer is deposited on the flexible substrate inner surface. In use, the resistive layer contacts at least two conductive traces in response to pressure applied to the flexible substrate to produce an electrical signal indicative of applied pressure. |

A method of manufacturing a movable contact unit includes manufacturing a movable contact, sticking the movable contact to a base sheet made of insulating resin, and applying demagnetization to the movable contact so that the residual magnetic flux density is smaller than the operation magnetic flux density of the magnetic sensor. In manufacturing the movable contact, elastic metal plate material is processed into a downwardly opening dome shape to form the movable contact. In a method of manufacturing a switch panel, the movable contact unit is overlaid on a wiring board having a contact, including pair an outer fixed contact and a central fixed contact, that corresponds to the movable contact so that the lower end of the outer periphery of the movable contact is mounted on the outer fixed contact. |

A method for manufacturing low cost electroluminescent (EL) illuminated membrane switches is disclosed. The method includes the first step of die cutting, embossing or chemically etching the metal foil surface of a metal foil bonded, light transmitting flexible electrical insulation to simultaneously form one or more front capacitive electrodes, membrane switch contacts and electrical shunt, electrical distribution means and electrical terminations that together comprise a flexible printed circuit panel. This continuous flexible printed circuit substrate is then coupled to a precisely positioned indexing system. Next, the front metal foil capacitive electrodes arc coated with a light transmissive electrically conductive layer. Then, a layer of electroluminescent phosphor is applied to the electrically conductive layer, a layer of capacitive dielectric is applied insulating the phosphor layer, a rear capacitive electrode is then applied over the capacitive dielectric layer, thus forming an electroluminescent lamp portion. Next, a transparent dielectric coating is applied to the entire surface of the lamp and substrate with open portions exposing electrical terminations, switch contacts and shunt. A spacer is applied to surround the switch shunt, providing an isolation barrier. An intermediary material is applied to the surface of the isolated rear EL electrode thus forming a switch actuator. Finally, the illuminated switch pattern is die-cut from the substrate material, and is then folded into three layers forming the final illuminated membrane switch. |

E-Board is a pocket portable, thin, light, small digital data input device, for use primarily by PDAs, cell phones or other mobile communicating computers (MCC). It has several versions, such a one pad or multi pad, integral to or detachable from MCC or even adhered to and covering the screen of MCC. It can encompass functions such as stylus, scroll, handwriting pad, etc., freeing much needed space for a larger screen. It can act also as MCC cover. Several techniques and devices are introduced that have also uses beyond MCC. |

The present invention is a flexible plastic membrane which supports embedded components such as light emitting diodes and plastic pressure switches, and conductors on a plastic ribbon which connects the embedded light emitting diode and plastic pressure switch to a connector. The flexible plastic membrane supports an adhesive which enables it to be stick to the surface of the module faceplate. The inventive structure is more economical to build and install than presently used mechanical spring loaded push switches and light emitting diodes as they must be physically mounted to the face plate and hardwired when the module is manufactured. In addition, the inventive structure can be replaced in the field when a fault develops without disturbing or disconnecting the optical fiber connected to the front or rear of a module. |

A remote control device for remotely controlling an AV (audio visual) device includes an analog switch (30) formed of an operating element (31 or 41) and a pressure-sensitive resistor (35) which outputs a signal with various levels depending upon a pressing force applied to the operating element (31 or 41). By employing the analog switch (30 ) in a control button of the remote control device, it becomes possible to output a signal having various levels depending upon a pressing force applied to the control button (31 or 41). This allows a single control button to be used for a plurality of functions. Thus, it is possible to reduce the number of buttons, and a user can easily operate the remote control device in a simpler fashion. |

A key device for a computer keyboard has a rigid printed circuit board, a flexible printed circuit board, and a key structure. The rigid printed circuit board has two adjacent but unconnected conductive ends electrically connected to two wires respectively. The flexible printed circuit board, fixed over the rigid printed circuit board, has a conductive segment installed above the two conductive ends, and an isolation layer installed around the conductive segment to form a gap between the conductive segment and the two conductive ends. The key structure is moveably fixed on the flexible printed circuit board in an up and down manner. When the key structure is pushed downward, the bottom of the key structure will touch the conductive segment of the flexible printed circuit board, and the conductive segment will touch the two conductive ends of the rigid printed circuit board to electrically connect the two conductive ends and the two wires. |

An inside case made of rubber is mounted in an outside case, a substrate integrally provided with an engine stop switch circuit and a switch electrode of an engine stop switch unit is assembled in the inside case, and its lower side is filled with curable insulating base material to be sealed. Further, a switch contact opposed to the switch electrode is formed of pressure sensitive conductive rubber, and a reversal spring is further interposed on the pressure sensitive conductive rubber. As a result, wirings are eliminated, a decrease in the size of the entire apparatus and simplification can be realized, and a metal contact is eliminated to improve durability. |
