CONTACT DEVICE WITH LIMITING ELEMENT, WHICH LIMITS DEVIATION OF MOVABLE CONTACT-PART Russian patent published in 2011 - IPC H01H31/28 

FIELD: electricity.

SUBSTANCE: invention relates to contact device of grounding switch (4, 5) or splitter with the first and second contact parts (7, 9), which move relative to each other along trajectory of motion. At least one contact part (7, 9) is equipped with a complying limiting element (12), which limits deviation of contact part (7, 9) across motion trajectory. Limiting element (12) joins the second contact part (9) with bearing element (6) in closed condition. Besides, the first contact part (7) is located at one end of movably installed bearing element (6), and in closed condition of contact device, the limiting element (12) rests bearing element (6) against the second contact part (9) and/or retention element (10) of the second contact part.

EFFECT: provides for reliable contact of movable arcs of contact parts relative to each other and prevention of contact interruption in complicated conditions and without additional mechanical load at finger elements.
