Title:
開閉接触子装置
Document Type and Number:
Japanese Patent JP4173006
Kind Code:
B2
Abstract:
A switching contact includes a rocker-type leaf spring as a contact force spring in order to produce the contact force required for a contact lever A drag bearing thereof is disposed between the point of rotation of the contact lever on a contact carrier and a contact-making end piece of the contact lever. Preferably, the drag bearing is formed by a bend of the contact force spring and a sliding surface disposed on the contact carrier. The drag bearing of the contact force spring can be displaced without a fixed link along the sliding surface according to the tension of the contact force spring. If the switching contract arrangement has several contact levers (multiple contact arrangement) all of the associated contact force springs can be combined to form a one-piece leaf spring.
