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.

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.

A circuit breaker with a circuit breaker housing that includes a switch-on button hole and a switch-off button hole, a button mechanism that includes a switch-on button and a switch-off button, the switch-on button including a switch-on button operating end slidably arranged in the said switch-on button hole, the switch-off button including a switch-off button operating end slidably arranged in the switch-off button hole. While the switch-on button operating end is being pressed toward the inside of the circuit breaker housing to enable the circuit breaker to switch on, the switch-off button operating end moves toward the outside of the circuit breaker housing, and while the switch-off button operating end is being pressed toward the inside of the circuit breaker housing to enable the circuit breaker to switch off, the switch-on button operating end moves toward the outside of the circuit breaker housing.

A plug-in circuit breaker that includes a circuit breaker housing, and a locking mechanism, an unlocking mechanism, and a button mechanism all arranged inside the circuit breaker housing, and an operating mechanism connected to the button mechanism, to drive the circuit breaker to switch on/switch off; the locking mechanism includes a first locking member with one end protruding outside the circuit breaker housing, and the circuit breaker housing comprises a locking member opening co-operated with the first locking member; the unlocking mechanism includes an independent pulling member drivingly co-operated with the first locking member, when the circuit breaker is in the switch-off state, one end of the first locking member protrudes outside the circuit breaker housing from the locking member opening, and pulling the pulling member enables the first locking member to retract into the inside of the circuit breaker housing.
