  • Patent number: 4112274
    Abstract: An electrical control for providing a graduated change in the magnitude of electrical energy transferred from a source of electrical energy to a device driven thereby including a mount, a plurality of load contacts disposed in fixed relation on the mount, a movable power contact engaging certain of the plurality of load contacts, a movable transition contact associated with the movable power contact first engaging each of the load contacts engaged by the movable power contact to provide an alternate full load current path through each of the load contacts engaged by the movable power contact prior to engagement by the movable power contact, thus providing a transition between the load contacts engaged by the movable power contacts which are connected to differing magnitudes of impedance substantially without arcing; and a third movable contact may be provided for selectively engaging other of the plurality of load contacts for effecting a switching function.
