A primary movable contact blade and a secondary movable contact blade are supported by these first and second neutral contacts, respectively, for seesaw motion. The operation of a lever causes the primary movable contact blade and the secondary movable contact blade through a pushrod to move in a seesaw motion in such a manner that a secondary movable contact provided on one end of the secondary movable contact blade contacts with an associated secondary fixed contact before a primary movable contact provided on one end of the primary movable contact blade contacts with an associated primary fixed contact, whereas after the primary movable contact of the primary movable contact blade is separated from the primary fixed contact, the secondary movable contact of the secondary movable contact blade is separated from the secondary fixed contact.

Abstract: An electric rocker switch is disclosed having a gull wing shaped rocking contact. The rocking contact pivots on a center terminal between a pair of upright blades. A centering protrusion disposed on a lower surface of the rocking contact rests between the uprights blades of the center terminal when the rocking contact is in a center position, thus preventing lateral movement of the rocking contact beyond the limits of the upright blades. First and second rocker contacts are located on opposite sides of the rocking contact. The first and second rocker contacts face toward first and second fixed contacts, respectively. Thus, the first rocker contact touches the first fixed contact when the rocking contact rocks to one side and the second rocker contact touches the second fixed contact when the rocking contact rocks to the other side. Positioning surfaces and top inside edges of the upright blades serve as pivots for the rocking contact as it rocks from side to side.

Abstract: Disclosed is an improved switch structure having forcedly opening-and-locking mechanism installed therein. It is responsive to the sticking of the movable and stationary contact elements for forcedly breaking an associated heavy-current carrying circuit which otherwise, would remain closed through the stuck contact elements. The forcedly opening-and-locking mechanism comprises an auxiliary contact section spring-biased to retain the stationary contact element in conductive condition to the associated circuit. It is responsive to the sticking-and-rising of the movable and stationary contact elements for allowing the stationary contact element to be apart from the conductive position to the associated circuit by yielding the rising force of the stuck contact elements until the locking position is reached, in which position the stationary contact element is kept in non-conductive position.

These curves can also help to improve the switching behavior of the switch with respect to the switching process and contact-making.

Stationary contacts are formed electrically common out of a single member having the stationary contact of one pole formed to be disposed below the rocking contactor and the stationary contact of the other pole formed to be disposed above its respective contactor.
