    Abstract: A tactile snap-action element for use in keyboards, the element comprising an arcuately shaped invertible first dome and a second dome shaped actuating protrusion extending from the invertible second dome, the actuating dome protrusion being integral with the invertible dome and being non-invertible. The element is operated by an actuation force which acts directly or indirectly through the non-inverting second dome to invert the first dome and to provide tactile feedback. The keyboard includes a plurality of keys, each key comprising an element, a conductive circuit associated with the first dome and movable with the inversion of the first dome to electrically contact a second conductive circuit associated with the element.

    Abstract: A push button switch has a spring contact plate and a circuit board in superposed position. The spring contact plate has one or more switch positions, each switch position comprising a prestressed domed portion surrounded by a flat sheet portion. The domed portion includes a central portion and radial webs connecting the central portion to the flat sheet portion. Spring contacts extend radially from the central portion, each contact between a pair of webs. The domed portion is prestressed to assume a stable position offset upwards from a plane coincident with the flat sheet portion, and the webs each have an upwardly bent portion at the junction with the flat sheet portion. A push button acts on the central portion and pressure on the push button causes the central portion to snap through the plane of the flat sheet portion, with the spring contacts contacting contact areas on the circuit board. Release of the push button enables the domed portion to snap back to the stable position.

    Abstract: Disclosed is a keyboard encoder capable of directly encoding decimal input information into electrical binary code. The electrical encoding of the information appears at the output terminals of the encoder when the key representing the information to be encoded is depressed. The depressed key causes the selective shorting together of certain ones of a group of encoding conductors which are connected to the output terminals.

    Abstract: A switching device for breaking an electric current including a main contact carrier, movable and stationary main contacts, the movable contact attached to the main contact carrier, an arcing contact carrier, a movable and stationary arcing contacts, the movable arcing contact attached to the arcing contact carrier and the stationary arcing contact arranged in parallel with the stationary main contact, and an actuating unit for the main and arcing contact carriers between open and close position at an actuating distance, wherein there are separation distances between the stationary and movable contacts of the main and arcing contact units respectively when the current is interrupted. The switching device further includes a first rack and a first gear for actuating the arcing contact carrier so that, when interrupting the current, a separation distance between the arcing contacts is longer than a separation distance between the main contacts.
