摘要： Electrical contact system with a first and a second contact (1, 5), each having a contact surface (4, 8). The first electric contact (1) has a mesostructured electric contact portion (14) with a plurality of slots (15) and ridges (16) formed between neighboring slots (16) of the plurality of slots (16). These slots (15) and ridges (16) extend in a direction running transversely to said switching plane (X-Z) form a plurality of current paths (16). The current paths (16) are inclined to the first contact surface (4) at a first angle (17) measuring less than 60 degrees such that an interruption current (12) flowing through the mesostructured electric contact portion (14) and through an electric arc (11) extending in between the first contact surface (4) after lifting the first contact surface (4) off the second contact surface (8) pushes said electric arc (11) in the direction of the apex of said first angle (17) from a first position (18) to a second position (19).

摘要： The present invention relates to a rotary switch. In particular, the rotary switch includes a main contactor having a main contact carrier and a main cam, a shaft rotatably journaled in the main contactor and extending axially through the main contactor, and an auxiliary contactor. When the switch is rotated from the ON position to the OFF position, the shaft rotates to break open auxiliary contacts before main contacts break open upon further rotation of the shaft.

摘要： In order to reduce the breaking energy of a high-voltage or medium-voltage circuit-breaker, the interrupting chamber (10) contains two contacts (12, 14) mounted to move in opposite directions, and actuated via a single device (20). The two contacts (12, 14) are surrounded by an insulating casing (18) of tubular shape, coupled in fixed manner to the main contact (12). The contacts (12, 14) are actuated by a device having a lever (24) in which each lever arm is coupled to a link, one of the links (32) being secured to the insulating casing (18) and the other link (34) being secured to the second contact (14). The guiding of the drive tube (18) on the main contacts (12b, 14b) makes it possible to improve breaking by keeping clean gas between said main contacts.
