Abstract
463,604. Mechanical switches without quick action; two-part couplings. NAAMLO.OZE VENNOOTSCHAP PHILIPS' GLOEILAMPENFABRIEKEN. Aug. 5, 1936, No. 21576. Convention date, Aug. 8, 1935. [Class 38 (v)] [Also in Group XXXVI] A multiple change-over device particularly for wireless sets and for use with different voltages comprises a number of main contacts a<1>, a2 . . . a<6> arranged at the corners of a regular polygon, an equal number of auxiliary contacts b<1>, b<2> ... b<6> or c<1>, c<2> ... c<6> &c. arranged round each main contact and a rotary member 2 carrying conducting bridges h, j, k, l, m, n adapted to connect the main contacts to selected auxiliary contacts. In the form shown, the main and auxiliary contacts are in the form of pins extending through to both sides of an insulating plate 1 and the member 2 is mounted on a bolt so as to be movable away from and towards the plate 1 as well as rotatable about the bolt. The bridges h, j . . . n, terminate in sleeves 5 which are adapted to fit over the pin-like contacts. Fig. 2 shows one position of the device in which the bridges connect the main contacts to auxiliary contacts b<1>, c<1>, d<1> &c. Withdrawal of the member 2, rotation through 60‹ and return towards the member 1 will cause the bridges to assume the dotted position in which other auxiliary contacts are engaged.
