| 1 | Magnetically operated electrical switch | US45372274 | 1974-03-22 | US3863182A | 1975-01-28 | LAPOINTE LLOYD J |
| An electrical switch has a freely movable magnetic ball contact maintained in a first position out of engagement with at least one of a plurality of stationary electrical contacts by a permanent magnet. The ball contact is movable to a second position wherein it engages all of the contacts in response to magnetic influence exerted thereon by an iron rod carried by a reciprocally movable push button and disposed within a flux path of the magnet. The rod exerts greater magnetic influence on the ball contact than magnet during only an initial portion of push button travel toward a fully depressed position whereby to cause the ball contact to return to its first position in response to magnetic influence of the magnet before the push button reaches its fully depressed position.

| 2 | Multiple circuit control switch having articulated cascaded operating mechanism | US433593 | 1974-01-15 | US3931483A | 1976-01-06 | Paige W. Thompson |
| 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. | ||||||
