In the figure, 5 is a movable contact, 5a is a movable contact, 6 is a movable arm, 12 is a lower link, that is, the first link, 13 is a fredle, 14, 15, 26 is a shaft, 16 is an insertion handle, 17
is a toggle spring, 27 is an upper link, that is, a second link,
28 is a spring hanging shaft, 29 is a toggle link mechanism, 30 is a fixed contact, and 30a is a fixed contact. Note that the same reference numerals in the figures indicate the same or equivalent parts.

Claims

[Scope of utility model registration request]

(1) A movable contact provided so as to be able to move toward and away from the fixed contact, a first link connected at one end to the movable contact, and rotatably supported by the other end of the first link. and an operation of driving and moving the movable contact through a second link whose one end is pivoted to a support point, and the second link at a position other than the line connecting the pivot point and the support point, and both links. An electric switchgear equipped with a toggle spring stretched between the handle and the handle.

(2) Utility model registration claim No. (1) characterized in that one end of the torge spring is suspended near the pivot point.
Electrical switchgear as described in section.

(3) Utility model registration claim (2) characterized in that the line connecting the pivot support point and the support point and the line connecting the pivot support point and the tension point of the toggle spring are shaped like an abbreviation. Electrical switchgear as described.

(4) Any one of claims (1) to (3) of the claims for utility model registration, characterized in that one end of the second link is pivoted to a fredle that is normally locked to a tripping mechanism. The electrical switchgear described in .
