In an arrangement and a method for driving a movable contact of a vacuum interrupter in a high-voltage circuit breaker, an actuating rod forms an element of a kinematic chain of the high-voltage circuit breaker. A lever element can rotate about an axis and can be mechanically connected to a drive via a connection element. A coupling element is configured to mechanically movably couple the actuating rod and the lever element. The actuating rod and the coupling element each have a longitudinal axis. The longitudinal axes are situated substantially on a common axis at a point in time when a separating action of the vacuum interrupter occurs.

An electrical switching device with separable contacts includes a switching apparatus including a fixed electrical contact and a mobile electrical contact that can be moved between a closing position and an opening position; a control lever mechanically coupled to the mobile electrical contact, the control lever being rotatable, about a first axis of rotation, between a first position and a second position; an anti-rebound lever arranged so as to move from a rest position to an opened-out position when the control lever reaches the second position. The anti-rebound lever engages a stop when it is in the opened-out position thereof and when the control lever is in the second position so as to prevent the control lever from leaving the second position.

A drive mechanism is for a vacuum switching apparatus. The vacuum switching apparatus has a stationary contact and a movable contact structured to move into and out of engagement with the stationary contact in order to connect and disconnect power, respectively. The drive mechanism includes a drive rod structured to drive the movable contact into and out of engagement with the stationary contact, the drive rod being movable along a longitudinal axis, and a number of toggle assemblies each having a component and a biasing element coupled to the component. The component is coupled to the drive rod. The biasing element is structured to bias the drive rod in a direction not coinciding with the longitudinal axis.

A multifunctional switch manipulator is provided. The manipulator includes a first switch unit, which is curved to be convex at the upper surface thereof, a second switch unit, which is disposed at a first side of the first switch unit and which extends radially in a first direction, and a third switch unit, which is disposed at a second side of the first switch unit and which extends radially in a second direction opposite the first direction. Each of the second and third switch units includes a housing that has an opening and a rotary knob disposed at the housing to be rotatable in a direction in which the opening extends, and at least one surface of the rotary knob is exposed to an outside through the opening.

The electric switch comprises at least one key (4) that pivots about a pivoting axis (5) and a base (2) provided with at least one electric connection and disconnection actuation point (3), so that the pivoting of the key 4 causes the application of pressure to at least one actuation point 3 and causes the electric connection or disconnection, and it is characterized in that the base (2) comprises at least one pivoting actuator (6). A low-cost mechanical type electric switch is obtained which automatically returns to its rest position, and which for the user has the same sensation as an electronic type electric switch.

A contactor module is adapted to detect a switching state of a contactor. The contactor module includes a movable element that is arranged to transmit the movement of a switching element of the contactor to the contactor module; and a deflection lever attached to the movable element. The deflection lever is arranged to indicate the switching state.
