Abstract: An adjustable circuit breaker portion of a multiple contact secondary contact assembly for mating with spaced, non-adjustable contact terminals of a circuit breaker enclosure, which includes a mounting rail and at least two contact modules. The contact modules a disposed on the mounting rail so that the contact modules align with the contact terminals.

Abstract: An electric rocker switch is disclosed having a gull wing shaped rocking contact. The rocking contact pivots on a center terminal between a pair of upright blades. A centering protrusion disposed on a lower surface of the rocking contact rests between the uprights blades of the center terminal when the rocking contact is in a center position, thus preventing lateral movement of the rocking contact beyond the limits of the upright blades. First and second rocker contacts are located on opposite sides of the rocking contact. The first and second rocker contacts face toward first and second fixed contacts, respectively. Thus, the first rocker contact touches the first fixed contact when the rocking contact rocks to one side and the second rocker contact touches the second fixed contact when the rocking contact rocks to the other side. Positioning surfaces and top inside edges of the upright blades serve as pivots for the rocking contact as it rocks from side to side.

Abstract: A vehicular input device is disclosed whose mounting posture can be adjusted freely in conformity with the physical constitution and form of an operator and which is superior in both versatility and operability. A transfer plate is connected to a ball screw through a nut so as to be moved forward and backward by a first motor. A rotary shaft, which is rotated by a second motor, is mounted on the transfer plate, and a housing of the vehicular input device is fixed to end portions of the rotary shaft. The first motor is rotated forward or reverse by operating a manual operating unit provided in the vehicular input device, thereby causing the housing to move forward or backward respect to a dash board. Likewise, the second motor is rotated forward or reverse by operating the manual operating unit, thereby causing a front end portion of the housing to turn upward or downward with respect to the dash board.

Abstract: The setting of a sensitivity of an acceleration detection device is performed by regulating the characteristics of a compression coil spring such as an initial load or a spring constant of the compression coil spring and by regulating the dimension of a mass body in an axial direction of a slide shaft. Further, a compression coil spring is used which has non-linear deflection-load characteristics.

Abstract: A fused mechanical interlock in an electrical switching device precludes a fuse access door from being open when the switching device is energized. The fused mechanical interlock optionally cooperates with a plug interlock mechanism which prevents the switching device from being energized unless a plug is properly inserted in a receptacle.

Abstract: A flexible shunt in the form of a flexible member made up of a stack of electrically conductive laminations each of a thickness of no more than about 0.002 inch (0.051 mm) has a moveable end secured by a moveable mount to a moveable contact support of an electric power switch for movement along a linear path. A fixed mount secures the fixed end of the flexible member to a fixed conductor termination spaced laterally from the moveable end along a neutral axis perpendicular to the linear path of the moveable end by an offset distance such that the installed length of the intermediate section between the fixed and moveable ends is less than the free length of the intermediate section. With this arrangement the stroke of the moveable end along the linear path can be up to at least ⅓ and even ½ of the free length of the intermediate section of the flexible member and with very low operating forces.

Abstract: A push button switch of the invention has base rubber having actuator portions, a resin molded portion attached to the base rubber, and a permeable film formed on the surface of the resin molded portion. More preferably, a flange portion of the film is disposed so as to avoid a region just above thick portions such as base plate supported portions of the base rubber. A push button switch capable of preventing peeling of coating or the like and intrusion of water can be therefore provided. A push button switch and a switching device which have satisfactory touch and can be thinned can be provided.

Abstract: An acceleration-sensing mass/magnet is positioned about the center activation region of a reed switch. Motion of the acceleration-sensing magnet in either direction along the reed switch causes the reed switch to close. A first mechanism for sensing shock in a first direction is contained between a flange and a lid connected by a cylindrical wall. The flange and lid ride a plastic tube that contains the reed switch. The acceleration-sensing magnet travels between the flange and the lid on the tube. A second mechanism for sensing shock in a second opposed direction is formed by positioning a second mechanism about the magnet and the first mechanism. The second mechanism for sensing shock has a spring that biases the lid of the plastic sleeve against an abutment formed by a portion of a plastic capsule that encloses the entire shock sensor.

Abstract: A push-button switch with overload protection and automatic reset is disclosed. The switch comprises a housing, a conducting unit, and an actuating unit. The conducting unit comprises several terminals, a normal-opened first conducting leaf and a thermally deformed bimetal sheet. The bimetal sheet is of a U shape having a working end and an opening end. The working end can deform to an overload position from a normal position in response to overload occurred in the conducting unit. The actuating unit comprises a stem, a locating cantilever, a rocking lever, an enabling rest, a cantilever pusher, and a lever reseating member. By means of the above structure, even though the stem is jammed, a trip action is still exactly performed in case of overload. Moreover, the switch of this invention will automatically reset when overload occurs by virtue of the cantilever pusher.
