Abstract: A movable contact body and a switch using the same are provided to prevent deterioration in a feeling of clicking by using a base sheet made of polyurethane resin. A movable contact body comprises a base sheet(1), a movable contact(3), and a pressurizing protrusion(4). The base sheet, made of thermoplastic polyurethane resin, has the first side and the second side which is opposite to the first side. The movable contact, dome-shaped, is formed at the first side, or the bottom surface of the base sheet. The pressurizing protrusion, formed at the second side of the base sheet, is located at a position corresponding to the summit of the dome shape of the movable contact. The movable contact body comprises an adhesive layer(2). The adhesive layer, installed on the first side of the base sheet, adhesively maintains the movable contact.

Abstract: A pressure sensing conductive sheet and a panel switch using the same are provided to prevent a change of a resistance value between fixed contacts by dispersing a soft particle and a hard particle inside a resistor layer. A pressure sensing conductive sheet(16) includes a substrate(11) and a resistor layer. The resistor layer includes a low resistor layer(12) and a high resistor layer(13). The low resistor layer is formed on a bottom surface of the substrate. The high resistor layer is formed on a bottom surface of the low resistor layer. A soft particle(14) and a hard particle(15) are dispersed inside the high resistor layer. An average particle size of the soft particle is larger than an average particle size of the hard particle. A plurality of fixed contacts(6A,6B) is arranged on a bottom surface of the pressure sensing conductive sheet.

Abstract: A movable contact unit includes a base sheet made of polyurethane resin, a domed movable contact made of thin metal sheet, and a pushing protrusion. The movable contact is held on a first face side of the base sheet. The pushing protrusion is formed on a second face of the base sheet at a place corresponding to a domed top of the movable contact.
