Abstract

340,043. Switch contacts. KESL, K., 13, Na Slupi, Prague. Sept. 25, 1929, No. 29097. [Class 38 (v).] A contact device for electric apparatus comprises one or more spring- actuated contact fingers a each made of a single piece and fitted between the stationary contact point d of a support k and a movable contact g. Each finger is shaped at one end to form an oblique sliding contact surface for the moving contact, in the centre to form a recess adapted for co-operation with the stationary support and at the other end to form a stop d<1> and a seat for the spring e. In a modification the ends of the supports are part cylindrical in shape and have more than half of their surfaces enclosed by the fingers ; the bottom of the bearing in the fingers being recessed to ensure no contact at these points.
