Abstract
447,253. Switch and fuse contacts. HOPE, V., Upton Hall, Macclesneld, Cheshire. Dec. 31, 1935, No. 36027. [Class 38 (v)] In a switch, fuse or like contact having bent over portions adapted to be engaged by a movable contact member such as a blade, the bent over portions consist of two parts 1, 2, separated from each other bv slits and situated at different distances from the base so that the blade parts company successively with the parts 1, 2 and the part 2 alone takes the spark. Fig. 6 shows such a contact engageable by a blade, and Fig. 7 another form in which the parts 1, 2 are bent over outwardly and are engaged by portions B of the movable switch arm. Fig. 5 shows a blank from which a contact somewhat similar to that of Fig. 6 is formed, slits 3 separating the parts 1, 2 and the folds of these parts taking place along the lines la and 2a.
