| 20100282579 | ELECTRICITY METER CONTACT ARRANGEMENT - At least one electrical contactor is provided that includes a fixed contact and a movable contact. The fixed contact includes a center leg and first and second arms that extend in opposite directions from the center leg. The movable contact associated with each fixed contact includes first and second blades positioned on opposite sides of the center leg. The first and second blades extend parallel to the center leg of the fixed contact such that when current flows through the electrical contactor, the current flow creates a force to push the first and second blades into the first and second arms of the fixed contact. The electrical contactor includes an actuating arrangement having a pair of cam members. The movement of the cam members causes pegs on each of the first and second blades to travel within the cam channel, thus opening and closing the contactor arrangement. | 11-11-2010 |

| 20160163478 | ELECTRICAL PUSHBUTTON SNAP SWITCH - An electrical snap on switch includes a pair of associated contact elements, the contact elements include a fixed contact element and a movable contact element arranged facing the fixed contact element and that may come into contact with the fixed contact element for establishing a first conductive path. The snap on switch may also include a snap-action switching device that includes a tilting driving member pivotally mounted around a horizontal axis between an upper position and a lower position. The movable contact element is a movable portion of an elastically deformable conductive blade. The driving member includes a cam, which cooperates with a cam follower portion of the blade to deform or relax the blade, to cause the movable contact to come into contact, or out of contact, with the fixed contact element, therefore to realize switching. | 06-09-2016 |
| 200273000 | Rotary | 5 |
| 20100243415 | SWITCH - A switch includes a blade-type moving contact that extends in a radial direction from a turning center and reciprocates such that its free end draws a turning locus, and a fixed contact that moves toward and away from the moving contact in a turning range of the moving contact. The blade-type moving contact and the fixed contact are accommodated a tank. The moving contact is supported by the movable-side support conductor. The fixed contact is supported by the fixed-side support conductor. An opening through which the moving contact enters is arranged to be opposed to a turning center of the moving contact. The movable-side support conductor and the fixed-side support conductor are arranged substantially on a same straight line extending along a center axis of the tank. | 09-30-2010 |
| 20120325632 | MOVEABLE CONTACT CLOSING ENERGY TRANSFER SYSTEM FOR MINIATURE CIRCUIT BREAKERS - An energy transfer system absorbs impact forces and/or energy from a moveable conductive blade directly attached to a moveable contact in a circuit breaker. The energy transfer system includes a rotatable member and a biasing member. The rotatable member has an axis of rotation about which the rotatable member is rotatable between a first position and a second position. The rotatable member further includes a protrusion. The protrusion has an initial curved engagement surface portion, a planar engagement surface portion next to the initial curved engagement surface portion, and a final curved engagement surface portion next to the planar engagement surface portion. The biasing member biases the rotatable member towards the first position. The movable conductive blade impacts the initial curved engagement surface portion to cause the rotatable member to begin to rotate about the axis of rotation such that the moveable conductive blade then contacts the planar engagement surface portion and then the final curved engagement surface portion. | 12-27-2012 |
| 20160111235 | SWITCH DEVICE FOR AN IGNITION SYSTEM - The present invention relates to a switch device for ignition systems and, more particularly, for use in cooking equipment or heating systems in general, such as to obtain the electrical contact necessary to generate the spark for activating the burner. More preferably, the present invention includes innovative functional and technical aspects capable of promoting the electrical contact necessary to activate the burner, but principally to increase the levels of safety in relation to movement of the controls of cooking equipment/heating equipment, principally in connection with the return movement of said control. Therefore, the present switch device comprises a casing formed by a lower structural body and another, upper structural body, which engage with one another in such a manner as to accommodate, within, flexible contact blades and a rotary core, the structural bodies having contact surfaces provided with at least one projecting portion; furthermore, an axially moveable commutator ring is engaged on said rotary core. | 04-21-2016 |
| 200274000 | With support | 2 |
| 20100219053 | SWITCH - A fixed contact includes a pair of conduction members that are arranged opposedly and in parallel to each other such that tip ends of the conduction members are oriented toward an opening, a support frame (pedestal member) that tiltably supports bases of the conduction members, a leaf spring (pressurizing member) that biases the conduction members in a direction in which the tip ends of the conduction members approach each other, and an outer frame (shielding member) that covers peripheries of the conduction members and the leaf spring and shields them from an outside electric field, the leaf spring is arranged on an outer side of the opposed conduction members, and the outer frame is engaged with the tip end of the conduction member, thereby maintaining an opening width between the tip ends of the conduction members at a predetermined width. | 09-02-2010 |
| 20110214970 | Resistance Device For High Voltage Switch Assembly - A resistance device for an electrical switch assembly includes a housing having a base and first and second support brackets extending outwardly therefrom. The base receives first and second conductive blades of the electrical switch assembly. A cam member is movably connected to the first and second supporting brackets. First and second spring members are connected between the base and the cam member and bias the cam member away from the base. The amount of force required to open and close the switch assembly is increased by having to overcome the resistance force imparted by the first and second spring members on the cam member during rotation of the conductive blades. | 09-08-2011 |
