  • Patent number: 4766278
    Abstract: The sealed toggle action switch comprises an operating lever having a front operating arm projecting out of the front component of the casing. The lever has a rear arm, projecting into the casing and carrying a contactor plate for relative sliding and swinging movement. A coil spring is received around the rear arm and is compressed between the contactor plate and the front sealing flange of a soft resilient sealing boot, such sealing flange being compressed against the operating lever. The boot has a rear, outwardly projecting sealing flange which is retained between the front and rear casing components. The contactor plate has a pair of J-shaped flanges which are slidably engageable with first and second fixed contacts having forwardly projecting protuberances, affording a detent action with the J-shaped flanges. In one position of the operating lever, the J-shaped flanges of the contactor plate engage both of the first and second contacts.

  • Patent number: 4730090
    Abstract: The switch includes a rotatable electrically insulating carriage having first and second contactors mounted thereon and facing in opposite directions from the path of the carriage, for a sliding engagement with first and second sets of fixed contacts. The contactors are biased in opposite directions, toward the contacts, by an electrically insulating switch assembly, mounted in a cylindrical opening in the carriage, and comprising a cup-shaped insulator having a cylindrical portion slidably mounted in the cylindrical opening. The insulator having a cup-shaped spring nest therein, for receiving one end of a coil spring. Biasing forces are exerted against the contactors by an end portion of the insulator and the opposite end of the coil spring. The cup-shaped insulator guides and locates the coil spring while obviating any electrical connection between the first and second contactors.

  • Patent number: 4679588
    Abstract: A single rotary shaft connected to a single rotary carriage operates a vacuum selector valve and two rotary electrical switches, in a casing having rear and front components. The valve comprises a valve carriage, slidable along a linear channel in the rear component. A gear rack on the valve carriage meshes with a pinion gear on the rotary carriage. The valve carriage is slidably retained in the valve channel by the switch contact plates of the first rotary switch. Such contact plates have terminal portions retained between the front and rear casing components. The contactors of the two switches face in opposite directions on the rotary carriage and are biased by a single coil spring, insulated from one of the contactors by a cup-shaped insulating member. The contact plates of the second switch are mounted on the front casing component and have terminals extending outside of the rear casing component through slots therein.

  • Patent number: 4556764
    Abstract: An electrical switch is disclosed, including contact plates having fixed contact portions which are slidably engageable by at least one movable contactor. At least one plate has a submarining crossover portion bent into a U-shape and extending across an overlapping portion of another plate but in a different plane to obviate any electrical contact between the submarining crossover portion and the overlapping portion. The plates may be mounted on an insulating casing wall having a recess for receiving the submarining crossover portion. The plates may have first end portions formed as L-shaped hooks inserted into slots formed in the casing wall. At their opposite ends, the plates may have second end portions formed as L-shaped terminal portions including terminal flanges and terminal prongs. Such prongs may be received in notches formed in a casing end wall, and may be retained in such notches by tooth-like projections on a casing cover.
