Accordingly, the amount of energy applied to the circuit breaker may be reduced, and a breaking function of the circuit breaker may be enhanced. Furthermore, since a contact pressure between the moveable contact and the fixed contact has a constant change, a reliability on a conductive state of the moveable contact and the fixed contact may be enhanced. | 07-21-2011 |

The switch also includes a latching track with at least two latching notches, which are spaced from each other along the directions of movement. At least two switch units are arranged one beside the other for simultaneous actuation by the slide. A latching cam is movably guided on the slide perpendicular to its directions of translational movement and is urged towards the latching track by a compression spring. One of the latching notches in cooperation with the latching cam defines a rest position of the slide, in which the slide does not actuate the switch units. Another latching notch in cooperation with the latching cam defines an actuating position of the slide, in which the slide has actuated the switch units. The antagonistic springs force the slide to move into the respective other position, when the latching cam slides over an apex between the latching notches. | 08-20-2009 |

| 20100288610 | INERTIAL CATCH FOR AN AUTOMATIC TRANSFER SWITCH POWER CONTACTOR - A catch assembly coupled to the operating mechanism of the ATS is provided. The catch assembly is structured to arrest movement within the operating mechanism when the operating mechanism moves at more than the speed for which it was designed. That is, the catch assembly does not engage when the operating mechanism is stationary, or moving at a standard speed, i.e. the speed at which the operating mechanism was intended to move. When there is a strong over-current, such as during a withstand test, a magnetic field causes a movable contact to separate from a fixed contact assembly which, in turn, causes the operating mechanism to move at a speed that is faster than the standard speed. The catch assembly is structured to engage and arrest the motion of the operating mechanism when the operating mechanism moves at a speed that is faster than the standard speed. | 11-18-2010 |
