Patent number: 7442895Abstract: An electrical switch has a common contact body and a first selective contact body and a second selective contact body. A contactor is connected mechanically and in an electrically conducting manner to the common contact body. The contactor comprises an elastic, electrically conducting material. It is formed originating from the basic form of a leaf spring into a multifunctional part having a clamping area, a deformation area and a stiffened actuating area. The pre-tension of the contactor causes the contact fingers to be positioned against the contact surfaces of the first selective contact body. Pressure on the actuating area elastically deforms the contactor, and the actuating area pivots with the contact fingers so that the contact fingers switchingly enclose the contact surfaces of the second selective contact body.Type: GrantFiled: July 12, 2006Date of Patent: October 28, 2008Assignee: Cherry GmbHInventors: Guenter Bauer, Eduard Ruff

Patent number: 5973284Abstract: A push-button switch for use in electronic devices is provided which reduces stress on contact parts. A C-shaped elastic member is secured at one end to a bottom wall of a switch casing and engages a movable member at its other end. The movable member in turn pivotably engages a contact member having movable elastic arms which abut non-conducting inclined surfaces on the bottom wall of the casing when the switch is open. To close the switch, a knob disposed slidably within the casing is depressed, bringing a bottom surface of the knob into engagement with an end of the movable member and deforming the C-shaped elastic member by bringing its ends closer together. Further, the contact member is caused to pivot about the movable member and move toward the bottom wall of the casing. Consequently, the movable elastic arms of the contact member slide off the inclined surfaces and into electrical contact with stationary contacts in the bottom wall of the switch casing to form a conductive path.Type: GrantFiled: June 5, 1998Date of Patent: October 26, 1999Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Takuo Takenaka, Yasuchika Kudo

Patent number: 4894499Abstract: The electric push-button switch comprises a housing portion and a linearly moveable push-button portion. Guide columns at the housing portion and the push-button portion attain accurate linear guiding and rotational positioning of the push-button portion. These guide columns mutually interact or interengage and are in multiple line contact with one another. This multiple line contact extends in the direction of movement of the push-button portion. The length of such line contact is variable between a rest position and an operating position of the push-button portion. This line contact is greatest when the push-button portion assumes its operating position. A contact surface of a fixed counter contact comprises a planar slide surface for resilient contact arms carried by the push-button portion. The friction arising during the forced sliding movement of the resilient contact arms over the contact surface produces self-cleaning of the contacts and damping of contact chatter movements.Type: GrantFiled: September 26, 1988Date of Patent: January 16, 1990Assignee: Contraves AGInventors: Hans Beck, Heinz Waser, Peter Bettschart
