  • Patent number: 6586695
    Abstract: In a key switch device, an outer wall of an engagement member of a key top is interposed between a pinch shaft and an upper shaft of a first link member, while an outer wall of an engagement member of the key top is interposed between a pinch shaft and an upper shaft of a second link member. When the key top is pulled up, the pinch shaft and the upper shaft of the first link member cooperate with each other to pinch the outer wall of the engagement member, and the pinch shaft and the upper shaft of the second link member cooperate with each other to pinch the outer wall of the engagement member. Thus, when the key top is pulled up, the key top is removed together with the first and second link members, thereby facilitating reassembly and maintenance of the key switch device.

  • Patent number: 6576855
    Abstract: A switch, especially for heavy duty vehicle applications, utilizes solid state circuitry and a low voltage, low current touch pad switch, where the switching occurs directly on a printed circuit board and bulky wire terminations are eliminated. The switch includes a rocker, which pivots at its center point fulcrum causing the switch lever, housed inside the switch and attached to the rocker, to move in a particular direction. The configuration of the lever is such that the extending ears on opposite sides press against the elastomer seal and move a carbon contact against the integrated circuit traces on a printed circuit board, completing an electrical circuit. This condition occurs for either directional movement of the rocker. Housed within the lever is a spring-loaded plunger fitted with a roller (wheel) at its end. The roller rests on a predesigned detented ramp located as an integral part of the switch insulator.

  • Patent number: 6571457
    Abstract: A control panel for electronic equipment that satisfies the requirements of hermeticity, clearness of indication and operability and yet allows a cost reduction. A sheet made of a commercially available light-transmitting thermoplastic synthetic resin material is used as a substrate. Sheet recesses are formed on the sheet so that each print layer formed on the surface of the sheet is located on the inner side of the bottom of a sheet recess. The sheet recesses are filled with a synthetic resin material to form pushbuttons. A contact surface of a case cover and a contact surface of a pushbutton outer skin are kept in close contact with each other during injection molding. Therefore, there is no possibility of the resin material flowing between the contact surfaces. It is unnecessary to insert a mold member into the clearance between each pushbutton and the associated opening in the case cover. Because the clearance can be minimized, it becomes easy to achieve a size reduction and so forth.

  • Patent number: 6566619
    Abstract: A rocker switch with a shaft (30) that can be pivoted clockwise or counterclockwise from a neutral position, which reliably returns to the same neutral position without “play”, and which is of simple design. A coil spring (25) which extends around the shaft, has front and rear opposite coil end portions (24, 26) with corresponding spring ends (27, 29), and which has a spring middle (28). Arms mounted on the shaft include a first arm (39′) engaged with the front spring end and a second arm (39) positioned to engage the spring middle. When the shaft is turned clockwise from the neutral position, the arms turn the first spring end (27) and spring middle (28) clockwise while loading only the rear coil end portion (26). When the shaft turns counterclockwise, the spring middle (28) is prevented from turning by a spring center support (43), so only the front coil portion (24) is loaded.
