Abstract: A multiple switching apparatus comprising two spring-like switching members disposed in a tandem array with each integral with its metallic support base. The central area of each of the switching members is defined by a plurality of slots formed in the support base with the length and displacement of the slots defining the force-displacement characteristics of each switching member and, accordingly, of the tandem array. The top switching member moves downward until it produces a first switching function, with further movement of the top switching member effecting movement of the second switching member such that a second switching function is produced.

Abstract: A circuit interrupter having at least two sets of contacts that are electrically connected in series such that when the at least two sets of contacts are opened, they are opened simultaneously. This functions to increase the distance between the sets of contacts as the distance is additive for the series connected sets of contacts, which increases the arc voltage for breaking any arc that may form between the individual sets of contacts more effectively.

Abstract: The disclosure relates generally to key assemblies employed in electrical switch operating keyboard devices and more particularly to the improved assembly of parts forming an individual depressible key on such a keyboard. Each key assembly is comprised of parts cooperatively interfitting to provide both audio and tactile feedback for the keyboard as well as a bifurcated electrical contact provision. Included in each key assembly is a spring having a buckling beam member with two end supports that will resist a key depression, a hermetic rubber pad that will also resist key depression and a pair of spring straddling members depending from the key assembly for conveying forces employed to depress the key to the switch associated with the assembly to effect closure of the same as well as for substantially reducing if not eliminating a detrimental contact bounce encountered in the operation of such assemblies. The force transmitting pair of depending members cooperate with the straddle spring to provide a rocker or teetering motion in conjunction with the desired bifurcated action for assuring closure of the contacts.

Abstract: A tactile switch plate for a keyboard comprises a non-conductive member sandwiched between a pair of conductors, the member having a planar body portion provided with a plurality of outwardly deformed carrier portions corresponding in number and spacing to the number and spacing of the keys of the keyboard. Each of the carrier portions is resiliently flexible for movement toward the plane of the body and each carrier portion carries a preferably elastomeric switching member that is adapted to bridge the conductors and establish an electrical circuit between the conductors. The plate and switching members preferably are produced by a molding process and the elastomeric switching members are cured by heat generated by an electrical current.

Abstract: A low profile electromechanical keyboard switch, displaying very low electrical bounce. The switch key top bears against a generally cylindrical plunger which has a depressed flat portion on its side engageable with a tactile ball biased by a spring nested in the switch housing. Upon application of a force to the key top which exceeds a threshold value, the tactile ball is displaced from the flat and over the shoulder defined between the depressed flat and the cylindrical portion of the plunger. Sudden, positive movement of the plunger against an underlying contact leaf ensues. The contact leaf is branched into multiple contact fingers, and arranged with respect to an underlying contact plate so that wiping contact occurs between fingers and plate. The switch housing is configured to carry sufficient diodes and resistors to assure full control and encoding functions in the keyboard in which such switch may be mounted.

Abstract: A switch assembly and method of operation comprises a housing having top and bottom ends spaced about a longitudinal axis and a selectively movable knob coupled to a plunger arrangement having a shaft that extends from inside the housing to couple to the knob. The switch assembly also comprises a printed circuit board having at least one wiper for engaging a contact extending from the plunger arrangement. A step shaft projects from the shaft of the plunger arrangement such that when a maintained mode of operation is desired by the switch assembly, the step shaft engages a retaining assembly formed by a portion of the housing, and when a momentary mode of operation is desired by the switch assembly the step shaft is positioned such that is free from engaging the retaining assembly.
