Abstract

552,793. Regulating switches. WEST, W., and GEIPEL, Ltd., W. Feb. 7, 1942, No. 1660. [Class 38 (v)] The contacts 1 of a regulating switch are arranged in pairs, the contacts of a pair having faces 1a inclined towards one another, to form a V-shaped recess in which the moving contact, for example a roller 8, can rest. Preferably alternate contacts project more than the intervening contacts so that the roller &c. can only rest in contact with the two elements of a pair. The contacts may be arranged to have the moving contact engaging their outer edges as shown, or with the inner edges of the circularly arranged studs. Preferably the roller is borne by a box-form arm, the other end of which may have an insulating roller.
