Abstract

361,625. Heavy current and oil-break switches ; switch contacts. KESL, K., 13, Na Slupi, Prague. Nov. 26, 1930, No. 35583. Addition to 340,043. [Class 38 (v).] In a contact device for large currents of the kind described in the parent Specification, having jaws B, C, between which the knife D enters, each jaw comprises two or more narrow contacting portions, e.g. B<1> .. B<4>, a spring a is arranged between each pair of contacting portions and the pairs are held apart from each other by partitions E<1>, E<2>, E3 which have turned-over portions F which limit the outward swing of the contacts. The cavity N may be filled with a plastic mass which damps the movement of the contacts and protects the springs from corrosion. In a modification, Fig. 5, adapted for oil switches the blade spring a is replaced by a coil spring a arranged in two telescoping tubes the inner of which has an aperture through which oil can pass, thereby damping the movement.
