Abstract
An electrical switch having a plurality of means adapted to be movable generally sequentially for switching power through the electrical switch. A plurality of means are adapted to be conjointly and relatively movable disposed in cascaded articulated relation between the switching means at least some of the movable means being conjointly movable relative to at least some of the others thereof for effecting the sequential operation of the switching means. Methods and a system for generally effecting sequential operation of the switching means are also disclosed.
Claims45
In an electrical switch having a plurality of means adapted to be movable generally sequentially for switching power through the electrical switch;
- and a plurality of movable means adapted to be conjointly and relatively movable and disposed in cascaded articulated relation between the switching means, at least some of the movable means being conjointly movable relative to at least some of the others thereof for effecting the sequential operation of the switching means.
An electrical switch comprising a plurality of means adapted to be generally sequentially movable for switching power through the electrical switch, a plurality of means disposed generally in articulated cascaded relation between the switching means and movable for actuating them generally sequentially, and means for applying a force of varying magnitude under preselected conditions onto the actuating means to effect the switching means actuating movement thereof.
A method of generally sequentially actuating a plurality of means for switching power in an electrical switch comprising the steps of:
- a. disposing a plurality of means generally in cascading articulated relation between the switching means for actuating them;
- and
- b. applying a force established in response to a preselected condition to the actuating means for articulating them in a manner to distribute at least a portion of the force to each of the switching means for effecting the generally sequential actuation thereof.
A method of actuating a pair of sets of a plurality of means under preselected conditions for respectively switching power generally in sequence in an electrical switch comprising the steps of:
- a. establishing a variable force in response to the occurrence of at least one of the preselected conditions;
- and
- b. distributing the variable force for sequentially actuating the plurality of switching means in one set thereof prior to sequentially actuating the plurality of switching means in the other set thereof.
In a system having a plurality of separate circuits, and a plurality of means for respectively making the separate circuits to energize them generally sequentially;
- the combination therewith comprising means for establishing a generally increasing force under preselected conditions, and a plurality of means disposed in cascaded articulated relation with each other and driven in response to the increasing force for predeterminately distributing at least portions thereof to preselected ones of the circuit making means thereby to effect the generally sequential energization of the circuits.
