<p>The present invention relates to an electric current measuring tongs with magnetic circuit which opens by a combination of linear and rotary movements, wherein the magnetic circuit accommodated in a housing (12) consists of two elements (1, 2), of which one (2) is mounted pivotably on the housing whereas the other (1) is adapted to be moved in a linear movement relative to the first element so as to permit the pivoting of the element (2) to open the circuit. The facing plane faces (3, 4; 5, 6) of the constituent elements (1, 2) of the magnetic circuit consists of plane oblique sections intended to come into close contact during the closure of the magnetic circuit.</p> |
