Abstract: The switch has an axis (A) by which an axial coordinate (z) which runs parallel to the axis and a radial coordinate (r) which extends perpendicular to it are defined. An arcing contact piece (1), a current conducting element (2), and an arc-resistant element (3a) are provided. The arcing contact piece (1) has a hole (6) for directing an axial flow (4) of a gas (4) that is heated by an arc (5) which is based on the arcing contact piece (1) if applicable. The arcing contact piece (1) forms a planar contact (F) along with the current conducting element (2) in order to conduct a fault current (I) that flows through the arcing contact piece (1) and the current conducting element (2) during the time the arc (5) burns. The current conducting element (2) is shielded from the flow (4) near the planar contact (F) with the aid of the arc-resistant element (3a). The current conducting element (2) has an axial area (2a) in which a radial inner dimension (d2) of the current conducting element increases step by step or continuously as the distance from the planar contact (F) increases parallel to the axis (A). The axial area (2a) accommodates the arc-resistant element (3a).

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.
