Patent number: 7368672Abstract: A push-on switch includes a movable contact which has a projecting segment permanently connected with an outer contact and which is accommodated in a recess of a switch enclosure. A sheet with a center through hole for the movable contact is placed on the switch enclosure. The push-on switch also includes a metal cover with a cover terminal. The metal cover is attached to the switch enclosure such that a pressing segment faces a disc segment of the movable contact corresponding to the position of the center through hole with a predetermined vertical gap between the pressing segment and the disc segment. When a very low and weak force is applied on the pressing segment, the pressing segment comes into contact with the disc segment to change the state of a first-stage switch.Type: GrantFiled: August 2, 2006Date of Patent: May 6, 2008Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Yasunori Yanai, Hisashi Watanabe

Patent number: 7057128Abstract: A first stationary contact (i.e., center stationary contact) has a center contact point exposed at the center on the bottom of a recess in a square-shaped switch base as viewed from the above. The first stationary contact is disposed to the bottom of the recess with its lead paths extended along one of diagonal lines of the square-shaped switch base from the center contact point toward both side edges of the switch base. Second stationary contacts (i.e., outer stationary contacts) are arranged at positions along an outer brim of the recess in a line-symmetrical manner about the one of the diagonal lines in areas opposite each other along the other diagonal line. The first stationary contact and the second stationary contacts are arranged in this manner and secured into embedment by means of insertion molding in the bottom of the recess in the switch base of an insulation resin.Type: GrantFiled: November 28, 2005Date of Patent: June 6, 2006Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Shingo Oyagi, Yasunori Yanai, Yoshikazu Yagi, Hisashi Watanabe

Patent number: 6664491Abstract: In a switch, an elastic member made of elastic material includes a bar section, a conical section at its upper portion functioning as a first deforming section, and a second deforming section at its lower portion. A movable contact in a switch case is pushed with the lower end portion of the second deforming section. A bar section of an elastic element projects through a central hole of a cover fixed to the switch case. In this switch, a pushing force applied to the elastic element deforms the first deforming section elastically, and then the second deforming section deforms elastically, and thus, the switch operates. The switch can absorb fluctuations due to combination of components of an electronic appliance, and stabilize its manipulation feeling through eliminating looseness of an operation button of the appliance.Type: GrantFiled: October 22, 2002Date of Patent: December 16, 2003Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Yasunori Yanai, Hisashi Watanabe
