Abstract: The invention relates to as witching apparatus for closing and/or opening an electric circuit. It has an actuating unit (3, 5, 22)and a bistable mechanism(6). The actuating unit (3, 5, 22) is linearly movable between a first end position in which the switching apparatus is in a closed state and a second end position in which the switching apparatus is in an open state. The linear movement defines an axis. The bistable mechanism is arranged to ensure that the actuating unit (3,, 22) is held in either of the end positions. According to the invention,the bistable mechanism includes a cam means (7a, 7b) mechanically connected to the actuating unit (3, 5, 22) and at least one cam follower (8). The invention also relates to a use of the invented apparatus.

Abstract: The present invention relates to an electrical insulator 1 comprising: a first connector 2 of an electrically conducting material; a second connector 3 of an electrically conducting material; and an electrically insulating material 9 being arranged between the first connector 2 and the second connector 3, insulating said connectors from each other; wherein a part 11 of the first connector 2 extends past a part 12 of the second connector 3, partly enveloping said part 12 of the second connector. The invention also relates to a surge arrester arrangement, to a use of an electrical insulator 1 for insulating a surge arrester, and to a method for production of such an electrical insulator 1.
