<p>The invention is in the field of electrical switching. The contactor includes a control member (5) which moves in translation and is placed between two bars (12) and (13) made from an electrically conducting material. The control member includes a monobloc part interposed between the two bars and has bearing surfaces (5', 5'') enabling the control of the pivoting of the bars about axes perpendicular to the translation axis of the control member (5), to produce a sequential opening or closing of one set of pairs of contacts (8, 11) and of another set of pairs of contacts (9, 10). The invention is applicable to the control of the electrical powering of a pump to maintain the pressure of a fluid within a predetermined range.</p> |
