Abstract

755,782. Electromagnetic switches; contacts. ETABLISSEMENTS MERLIN & GERIN SOC. ANON. June 14, 1954 [June 16, 1953], No. 17383/54. Class 38(5) The flat contact surface between the contacts 3, 4 in a high-voltage switch is divided into two portions by a recess 5 provided in the contact face of at least one of the contacts and lying parallel to the axis of rotation of the movable contact assembly 2, 4, and each contact 3, 4 is provided with a slit 6, 7 lying parallel to the contact face and placed to divide the current path into two parallel paths F1, F2, having the same direction and flowing in each contact between the recess and the slit: Contacts 3, 4 may comprise the stationary and moving arcing contacts, 1 and 2 being the main contacts. The stationary contact 3 is. pivotally mounted on frame 8 by means of guides 10. 12. Guides 10 terminate in hooks 10a which act as stops for pin 11 integral with contact 3, and guide 12 has a slot in which an extension 13 of contact 3 slides. Contact 3 is urged outwardly by spring 14. As the contacts are closed the upper parts of the contacts 3, 4 meet, the upper part of contact 3 is pushed inwardly against spring 14 until the lower parts of the contacts meet. The inward movement of contact 3 continues until main contacts 1. 2 engage.
