The invention relates to an operating mechanism for opening and closing at least one contact, which operating mechanism comprises, a base frame, a bridge body movable relative to the base frame between a closed position and an opened position, a rod mechanism of a first and a second link, a cam arranged on a shaft, a locking lever fixedly arranged with one end to the first link and moves with the first rod between a locked position and an unlocked position, a control shaft having a D-shaft portion with a flat surface portion and a semi cylindrical surface portion, and a lock position, in which the path of the second end of the locking lever intersects with the circumference of the cross-section of the D-shaft portion.

Operating mechanism

The invention relates to a device for operating a switch having an operating lever for moving the switch between the open and closed position and an operating pin arranged to a moving part of the switch, wherein the device comprises a primary shaft, a secondary shaft arranged coaxially with the primary shaft, a coupling arranged between the primary shaft and the secondary shaft, a spring, a control lever extending in a radial direction from the primary shaft, a latch having a disengage lever extending in a radial direction from the primary shaft and a roller movable into the path of the disengage lever to limit rotation of the primary shaft in the first rotational direction; and, a reset lever extending in a radial direction from the secondary shaft.

Operating mechanism for a switch

An operating mechanism for operating at least one contact is provided. The operating mechanism includes a base frame and an operating rod that is linearly guided in the base frame for connection with at least one contact. The operating mechanism further includes a contact spring for urging the operating rod to the open position and a rod mechanism having two links, and each link has a first end and a second end. The operating mechanism also includes a cam follower arranged at the middle hinge of the rod mechanism, a cam arranged on a cam shaft, a cam shaft lock for lacking the shaft, and a closing spring. The opening section of the cam is configured such that the cam follower follows the profile of the opening section when the operating rod moves from the closed position towards the open position.

Operating mechanism for operating at least one contact

An operating mechanism for opening and closing at least two contacts simultaneously is provided. The operating mechanism includes a base frame and a bridge body having an elongate contact surface with a length and a width. The elongate contact surface is configured to extend in a length direction over and be in contact with operating rods of the at least two contacts. The operating mechanism further includes a first reaction arm extending substantially parallel to the length of the elongate contact surface and a second reaction arm extending parallel to the first reaction arm and at a distance of the first reaction arm in the direction perpendicular to the elongate contact surface. The operating mechanism also includes a rod mechanism of two links and a cam arranged on a shaft.
