Abstract: The invention relates to a switch provided with self-cleaning contacts used, in particular for actuating a horn for a steering wheel of a motor vehicle. The inventive switch comprises at least two opposite contacts one of which is movable and touches the opposite contact by means of an actuating element. The self-cleaning of the contacts is carried out by the reciprocal sliding thereof, the contact associated with the actuating element is fixed to a supporting element which is embodied in such a way that it is elastic and fixed to an end, an opposite end being free and moveable. Said invention is characterized in that the supporting element from the fixing side outward has an inclined line with respect to the direction of actuation in the direction of said actuating element, and subsequently in the direction of the free end thereof. A line is also inclined in the direction of the free end thereof with respect to the direction of actuation starting from the actuating element.

Abstract: In an elastic sheet member of the present invention, a silicon rubber sheet is supported by a fixed member. A wire group functioning as contacts is disposed at either one of the silicon rubber sheet or the fixed member. In other words, electrical continuity paths, which were conventionally provided at a printed circuit board, are basically provided at the elastic sheet member which is formed of a non-conductive material. In accordance with the present invention, there is no need for the printed circuit board to cover a range at which all rubber contacts are disposed, as in conventional art. Accordingly, the printed circuit board can be made compact, space required for placement thereof can be reduced, and degrees of freedom in design are increased.

Abstract: A key assembly comprising a base; a manually operable key secured to, and mounted above the base by, a resilient key mat having an upstanding wall. The key is moveable against the resilience of the upstanding wall towards the base. A guide assembly extends between the base and the key to guide movement of the keys. A membrane is supported on the base and carries a pair of electrically insulated first contacts, each first contact of the pair being connected to a respective electrical track supported on the membrane and extending to a connection location. A second contact is provided on the underside of the key or the key mat and has a size and position such that movement of the key towards the base causes the second contact to engage both first contacts and thereby electrically connect the first contacts.

Abstract: A "membrane"-type keyboard includes a resilient foam layer having an array of holes therein with the layer being sandwiched between first and second flexible membranes having electrical conductors thereon which are arranged to complete a circuit associated with a hole when the first and second membranes are moved toward each other. Embodiments including dome-shaped areas in the first flexible membranes provide for "tactile feedback" and additional foam layers enhance the operating characteristics of the embodiments. The method generally entails determining the operating parameters of a desired keyboard and simply changing the relative density and/or thicknesses of various layers and flexible membranes in the keyboard to obtain radically variable paremeters, as for example, the location of the "makepoint" of the switch at various positions between the start and end of "key travel."

Abstract: Provided is a contact device in which all of three movable contacts can be securely brought into contact with fixed contacts. The contact device includes a fixed terminal 37 that has a fixed contact 35, a movable terminal 28 that moves toward and away from the fixed terminal 37 and has three movable contacts 31a, 31b, and 31c that are brought into contact with the fixed contact 35, and a pressing spring 33 that presses the movable terminal 28 and brings the movable contacts 31a, 31b, and 31c into contact with the fixed contacts 35 at a predetermined pressing force. The point of application of the pressing spring 33 is located in a triangle formed by internal tangents of the three movable contacts.
