Abstract: A pressure actuated switching device is made by applying at least a first layer of fluid conductive polymeric coating material to a surface of a sheet of green rubber material. The conductive polymeric coating is solidified to form an electrode, and the sheet of green rubber material is vulcanized. Two strips of green rubber may be simultaneously processed and then joined such that the respective layers of conductive coating are in spaced apart opposing relationship. The conductive polymeric coating may optionally be formulated with green rubber. Optionally, a blowing agent may be included in the conductive coating formulation so as to provide a cellular polymeric foam piezoresistive material from which the electrode is constructed. The green rubber sheets may be processed by a continuous rotary method or by a linear method using a clamping press having opening and closing dies for heating and joining the strips of green rubber.

Abstract: In a multiple-direction input device, when the operation body is tilted, a push portion having a substantially spherical shape at the bottom of a operation body pushes a resistor element and detects a tilting direction and a tilting angle of the operation body from a resistance at a pressing point. Thus, the input device may operate in multiple directions in entire directions of 360null. The device can detect the pressing point of the push portion pressing the resistor element in accordance with the tilting direction and the tilting angle. The multiple-direction input device using less number of parts is capable of continuously detecting the tilting directions and the tilting angles.

Abstract: The present invention relates to a membrane switch which is not subject to stress relaxation at contacts and is resistant to the reduction in actuating force even if the ambient temperature of the switch becomes high. A first flexible insulating substrate having a first contact pattern and a second flexible insulating substrate having a second contact pattern are disposed in facing relation via a spacer member having an opening at an area in which the first contact patterns face each other; wiring patterns conductive-connected to corresponding contact patterns are provided on at least one of the first flexible insulating substrate and the second flexible insulating substrate; and the first and second contact patterns are conductive-connected by pressure applied to a contact comprising the first and second contact patterns. The wiring patterns are conductive layers containing resin made of a mixture of conductive powder and binder resin, and a part of the second contact pattern includes a layer containing resin that is more rigid than the binder resin.

Abstract: A switching apparatus which includes a rubber keypad (32, FIG. 2) with a rubber cap (36) that can be depressed by a person's finger to snap a snap dome (52) that connects contacts (21, 22) of a first switch (70), provides increased tactile feedback to the person's finger. A keycap (42) of rigid material includes a cover (44) lying on top of the rubber cap and also includes a stem (54) that projects down through a hole in the cap, with a lower stem end (60) lying above the snap dome to snap down the dome when a person's finger depresses the cover. The tactile snap feedback is transmitted directly through the rigid material of the stem to the rigid material of the cover, to the person's finger to indicate that the switch has been closed. The cap has a radially outer part (84), and an electrically conductive element (82) is mounted on the outer part to engage contacts (23, 24) of a second switch (80) to close it, before the snap dome is snapped to close the first switch. The coupling portion (38) is designed to not produce a tactile response, and the conductive element is preferably of conductive elastomeric material to avoid a tactile feedback that would falsely indicate that both switches were closed.
