Abstract

668,900. Switch contacts. ETABLISSEMENTS MERLIN & GERIN. Dec. 23, 1949. [Dec. 30, 1948] No. 32932/49. Class 38 (v). To prevent the welding together of heavycurrent air-break switch contacts to a degree sufficient to preclude their opening by the operating mechanism, the co-operating contact surfaces axe grooved or fluted, the grooves of one contact making an angle with those of the other to produce a number of small quadrilateral engaging surfaces. The grooves may be of rectangular, trapezoidal, triangular, or circular cross-section.
