Abstract: The invention relates to a method for controlling an electrical switching module which can be displaced between an entry position and an exit position. The switching module comprises switching contacts of vacuum switching tubes; an isolating element which can be also be displaced in the switching module and comprises isolating contacts which can be connected to, and disconnected from, corresponding mating contacts inside an enclosed switchboard section, as required; and connector contacts and mating connector contacts in the low voltage range. The switching contacts of the vacuum switching tubes support the closing and opening processes, under the control influence of a closing spring which can be influenced by a closing catch (EK) and an opening spring which can be influenced by an opening catch, and prominent functional positions of the isolating position.

Abstract: A locking device of an electrical switch which can be moved between a disconnected position and an operating position with the switching states of the electrical switch. A first strip has a control contour which extends in a first direction and has a ramp which interacts with a control rod which can be moved in certain states of the electrical switch.

The switching contacts of the vacuum switching tubes support the closing and opening processes, under the control influence of a closing spring which can be influenced by a closing catch (EK) and an opening spring which can be influenced by an opening catch, and prominent functional positions of the isolating element are represented by an “operating position” and by an isolating position.

Abstract: An actuating mechanism for a vacuum-type interrupter with a contact spring. The actuating mechanism of a vacuum-type interrupter has a pivotally positioned two-armed lever and a spring which holds the contact force ready and which engages with the lever. The two-armed lever is guided with limited displacement in a bearing in a direction which runs approximately parallel to the actuation direction of the interrupter. While enabling, the two-armed lever pivots about a bearing bolt around the end of the bolt guiding until the contact elements engage each other. The further pivoting of the lever takes place around a linkage assembly between the two-armed lever and the actuating impact rod. The two-armed lever can be formed from two parallel split levers with a clearance such that the spring can engage between the split levers. The actuating mechanism is suitable for one or multiple vacuum circuit breakers, e.g., for use in gas insulated switchgear.
