Contact Arrangement Or Composition Patents (Class 335/97)
  • Patent number: 8237523
    Abstract: The relay has a movable first contact, a second contact, and an actuating element operatively connected with an armature of the relay. The first contact is movable toward the second contact by the actuating element and dependent on a supply of current to the relay. A snap action spring connects the second contact to a housing of the relay. The second contact is positioned between two arrangements by the snap action spring.

  • Patent number: 7843289
    Abstract: An improved electromechanical switch designed to operate at frequencies from DC through microwave has terminal probe tips that are formed from an alloy of noble metal and contoured with a pattern of peaks and valleys in order to provide better contact wiping operation and capture of wear debris. The switch incorporates damper elements to reduce switching contact bounce, thus providing increased contact life as well as higher quality signal switching.

  • Patent number: 7642480
    Abstract: In order to reduce the breaking energy of a high-voltage or medium-voltage circuit-breaker, the interrupting chamber (10) contains two contacts (12, 14) mounted to move in opposite directions, and actuated via a single device (20). The two contacts (12, 14) are surrounded by an insulating casing (18) of tubular shape, coupled in fixed manner to the main contact (12). The contacts (12, 14) are actuated by a device having a lever (24) in which each lever arm is coupled to a link, one of the links (32) being secured to the insulating casing (18) and the other link (34) being secured to the second contact (14). The guiding of the drive tube (18) on the main contacts (12b, 14b) makes it possible to improve breaking by keeping clean gas between said main contacts.

  • Patent number: 7492244
    Abstract: A code switch for an electrical appliance comprises triggering magnets at specific points in a rotatable rotor. Stationary opposite contacts are disposed in the housing of the code switch and wipers are provided with contact heads assigned to said opposite contacts at a disconnecting distance. When a triggering magnet is moved above an opposite contact by rotating the rotor, the contact head is pulled upward by magnetic force towards the opposite contact and the contact is closed.

  • Patent number: 4564827
    Abstract: In a programmable control means for switching timers or chronometers, a magnetic field sensor having a ferromagnetically alloyed wire is disposed on a program carrier. A coil is brought into the proximity of the wire. A permanent magnet adjacent thereto has a magnetic field which influences the core polarity of the wire such that the coil emits voltage pulses given polarity changes therein for the control of an electric or of an electronic switch. According to the invention the sensor wire is releasably disposed on the program carrier.
