<p>The purpose of the invention is to create such protective electric switch, which should upon integration thereof into each desired electric circuit interrupt such circuit either in the case of thermal overloading or also in the case, when a short circuit current would occur, wherein in particular in the presence of short circuit current interruption of the circuit should be executed essentially quicker and more reliable as by currently known switches. Such switch comprises a casing (1), in which a stationary contact member (2) and movable contact member (3) are available, wherein said movable contact member (3) is controlled by means of interrupting mechanism (5), which is triggered by means of actuator (4) and connected with a switch lever (6). The movable contact (3) is conceived as an uniform lever, which is pivotally around its pivot point (30) embedded within the casing (1) and is allowed to be pivoted from its first stable position, in which it is rest onto the fixed contact (2), into its second stable position at certain distance apart from said fixed contact (2), and which is adapted to cooperate with the disconnecting mechanism (5), namely either with the disconnecting lever (51) or with the actuating lever (52) thereof.</p> |
