The present invention relates to a contactor device for high voltage applications, an energy storage system comprising the contactor device and a corresponding method for controlling the contactor device. A contactor device (100) comprises at least one fixed contact (106), at least one moveable contact (108), which is configured to move between an open position and a closed position, wherein in the closed position, the at least one moveable contact (108) electrically contacts the at least one fixed contact (106), and at least one first actuator (110, 120), which is configured to reversibly move the at least one moveable contact between the open position and the closed position. The contactor device (100) further comprises at least one second actuator (202) which is configured to move the at least one fixed contact (106) into a fired position, wherein in the fired position, the at least one fixed contact (106) is permanently disconnected from the at least one moveable contact (108).

A gear structure and a dimmer and speed control switch, wherein the gear structure includes a plurality of positioning grooves and a gear switching component, and the plurality of positioning grooves are sequentially spaced apart on the housing; the gear switching component is movably Installed on the housing, it includes a positioning component and a biasing component connected with the positioning component. The positioning component has a first position that is positioned and matched with the positioning groove and a second position separated from the positioning groove. The biasing component applies a biasing force on position component that moves it toward the first position, the gear structure mentioned above can ensure accurate gear positioning during the operation of the dimmer and speed control switch, and is not prone to misoperate, which is convenient for users, and coordinated positioning grooves and positioning parts have the advantage of simplified structure.

A circuit breaker with quick response and separation and a quick response and separation method for the circuit breaker. The circuit breaker comprises a breaking contact group and a joint contact group. The breaking contact group comprises a movable breaking contact. The joint contact group comprises a movable joint contact. A movable contact limiting device used for limiting moving positions of the breaking contact and/or the joint contact is arranged between the breaking contact group and the joint contact group. The quick response and separation method for the circuit breaker comprises a breaking and opening step, wherein the breaking contact moves in a reverse direction and is separated independently ahead of the joint contact, or the breaking contact and the joint contact both move in a reverse direction and are separated at the same time.

A switching assembly intended to be joined onto a control assembly provided with an actuation member, the switching assembly comprising a body, an electrical circuit comprising two fixed contacts, the electrical circuit being able to be controlled both by a control switch of a normally-closed type and by a monitoring switch of a normally-open type, linked in series with the control switch. The monitoring switch makes it possible to monitor the correct secure attachment of the switching assembly onto the control assembly by keeping the electrical circuit open as long as the control assembly is mechanically disconnected from the switching assembly.
