Bridging Contacts Patents (Class 200/243)
  • Patent number: 10987751
    Abstract: Apparatus for allowing a welder to control the output power of a welding machine, and thus its arc power by applying force to a surface of a force sensing transducer assembly. The force sensing transducer assembly generates a force signal based upon the force applied, for example by reducing the resistance within the force sensing transducer assembly. A control interface module then receives the force signal and controls the welding machine power output based upon the force signal. The welder may set the range of force to change the arc power by setting a minimum amount of force to actuate the welding machine and a maximum force that increases the output power of the welding machine (force below the minimum does not actuate the welding machine and force above the maximum does not increase the welding machine power above a certain level).

  • Patent number: 8119940
    Abstract: The present invention includes a contact block for a safety switch that has a support structure and a pair of electrical contacts that are fixed in position on the support structure. The contact block includes a contact block plunger provided with a bridging contact. The bridging contact extends through the contact block plunger, from one side to another, and protrudes from the sides of the contact block plunger. The contact block plunger is moveable in-between the fixed pair of electrical contacts to move the bridging contacts into and out of contact with the fixed pair of electrical contacts. A contact block guide extends along the support structure and between the pair of fixed electrical contacts and cooperates with the contact block plunger such that the contact block plunger is restricted to movement along the contact block guide.

  • Patent number: 8058574
    Abstract: An auxiliary contact block is disclosed for expanding a switching device and to a switching device having at least one auxiliary contact block. A compact auxiliary contact block, i.e. a block requiring little wiring and space, for a switching device is disclosed, and a switching device having at least one auxiliary contact block. In at least one embodiment of the auxiliary contact block, the auxiliary contact block includes auxiliary contacts disposed in a plane, the contacts having contact bridges and associated fixed contact pieces, and at least one contact slider, which can be equipped with at least one auxiliary contact pair. The configuration of the auxiliary contacts in a plane as described herein allows a very small installation size and very little wiring complexity of the auxiliary contacts in a simple manner. The actuating unit can, for example, be configured as a slider that couples the contact slider and the switching device with each other.

  • Patent number: 7990239
    Abstract: 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.
